In the current CATV system architectures, they provide one- way delivery of a common menu of entertainment to all the homes through the cable network. Through the technologies evolution, the interactive services (or two-way services) can be provided in the cable TV systems. They can supply customers with individualized programming and support real- time two-way communications. With a view to the service type changed from the one-way delivery systems to the two-way interactive systems, `on demand services' is a distinct feature of multimedia systems. In this paper, we present our work of building up an integrated multimedia system on interactive CATV network in Shih Chien University. Besides providing the traditional analog TV programming from the cable operator, we filter some channels to reserve them as our campus information channels. In addition to the analog broadcasting channel, the system also provides the interactive digital multimedia services, e.g. Video-On- Demand (VOD), Virtual Reality, BBS, World-Wide-Web, and Internet Radio Station. These two kinds of services are integrated in a CATV network by the separation of frequency allocation for the analog broadcasting service and the digital interactive services. Our ongoing work is to port our previous work of building up a VOD system conformed to DAVIC standard (for inter-operability concern) on Ethernet network into the current system.

Though intended to educate patients on the risks, benefits, side effects and alternatives within medical treatment, informed consent documents may have unanticipated consequences for patients. Patients may regard these forms as little more than a ritual to access treatment. Or patients may perceive that these forms exist to protect doctors rather than to contribute to a meaningful, patient-protective educational interaction. To rehabilitate the informed consent project, this essay considers the baggage that informed consent documents have acquired through practical use, explores patients' and providers' lived experience of informed consent, and considers whether a multimedia consent application would be a viable solution to the various difficulties that currently erode perceptions of and confidence in the informed consent process.

Speech information retrieval: a review

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hafen, Ryan P.; Henry, Michael J.

Audio is an information-rich component of multimedia. Information can be extracted from audio in a number of different ways, and thus there are several established audio signal analysis research fields. These fields include speech recognition, speaker recognition, audio segmentation and classification, and audio finger-printing. The information that can be extracted from tools and methods developed in these fields can greatly enhance multimedia systems. In this paper, we present the current state of research in each of the major audio analysis fields. The goal is to introduce enough back-ground for someone new in the field to quickly gain high-level understanding andmore » to provide direction for further study.« less

Multimedia plays a major role in medicine. Databases containing images, movies or other types of multimedia objects are increasing in number, especially on the WWW. However, no good retrieval mechanism or search engine currently exists to efficiently track down such multimedia sources in the vast of information provided by the WWW. Secondly, the tools for searching databases are usually not adapted to the properties of images. HTML pages do not allow complex searches. Therefore establishing a more comfortable retrieval involves the use of a higher programming level like JAVA. With this platform independent language it is possible to create extensions to commonly used web browsers. These applets offer a graphical user interface for high level navigation. We implemented a database using JAVA objects as the primary storage container which are then stored by a JAVA controlled ORACLE8 database. Navigation depends on a structured vocabulary enhanced by a semantic network. With this approach multimedia objects can be encapsulated within a logical module for quick data retrieval.

Eidenberger, Horst

2003-12-01

This paper describes how the web standards Synchronized Multimedia Integration Language (SMIL) and Scalable Vector Graphics (SVG) are used in teaching at the Vienna University of Technology. SMIL and SVG are used in courses on multimedia authoring. Didactically, the goal is to teach students how to use media objects and timing concepts to build interactive media applications. Additionally, SMIL is applied to generate multimedia content from a database using a content management system. The paper gives background information on the SMIL and SVG standards and sketches how teaching multimedia is organized at the Vienna University of Technology. Courses from the summer term 2003 are described and illustrated in two case studies. General design problems of SMIL-based presentations are modelled as patterns. Additionally, suggestions for improvement in the standards are given and shortcomings of existing user agents are summarized. Our conclusion is that SMIL and SVG are very well suited for teaching multimedia. Currently, the main problem is that all existing SMIL players lack some properties desired for teaching applications (stability, correctness, etc.).

This paper introduces the design and implementation of a Multimedia Data Repository served as a multimedia information system, which provides users a Web accessible, platform independent interface to query, browse, and retrieve multimedia data such as images, graphics, audio, video from a large multimedia data repository. By integrating the multimedia DBMS, in which the textual information and samples of the multimedia data is organized and stored, and Web server together into the Microsoft ActiveX Server Framework, users can access the DBMS and query the information by simply using a Web browser at the client-side. The original multimedia data can then be located and transmitted through the Internet from the tertiary storage device, a 400 CDROM optical jukebox at the server-side, to the client-side for further use.

Health consumers increasingly want access to accurate, evidence-based information about their medications. Currently, education about medications (that is, information that is designed to achieve health or illness related learning) is provided predominantly via spoken communication between the health provider and consumer, sometimes supplemented with written materials. There is evidence, however, that current educational methods are not meeting consumer needs. Multimedia educational programs offer many potential advantages over traditional forms of education delivery. To assess the effects of multimedia patient education interventions about prescribed and over-the-counter medications in people of all ages, including children and carers. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2011, Issue 6), MEDLINE (1950 to June 2011), EMBASE (1974 to June 2011), CINAHL (1982 to June 2011), PsycINFO (1967 to June 2011), ERIC (1966 to June 2011), ProQuest Dissertation & Theses Database (to June 2011) and reference lists of articles. Randomised controlled trials (RCTs) and quasi-RCTs of multimedia-based patient education about prescribed or over-the-counter medications in people of all ages, including children and carers, if the intervention had been targeted for their use. Two review authors independently extracted data and assessed the risk of bias of included studies. Where possible, we contacted study authors to obtain missing information. We identified 24 studies that enrolled a total of 8112 participants. However, there was significant heterogeneity in the comparators used and the outcomes measured, which limited the ability to pool data. Many of the studies did not report sufficient information in their methods to allow judgment of their risk of bias. From the information that was reported, three of the studies had a high risk of selection bias and one was at high risk of bias due to lack of blinding of the outcome assessors. None of the included studies reported the minimum clinically important difference for the outcomes that were measured. We have therefore reported results from the studies but have been unable to interpret whether differences were of clinical importance.The main findings of the review are as follows.Knowledge: There is low quality evidence that multimedia education was more effective than usual care (non-standardised education provided as part of usual clinical care) or no education (standardised mean difference (SMD) 1.04, 95% confidence interval (CI) 0.49 to 1.58, six studies with 817 participants). There was considerable statistical heterogeneity (I(2) = 89%), however, all but one of the studies favoured the multimedia group. There is moderate quality evidence that multimedia education was not more effective at improving knowledge than control multimedia interventions (i.e. multimedia programs that do not provide information about the medication) (mean difference (MD) of knowledge scores 2.78%, 95% CI -1.48 to 7.0, two studies with 568 participants). There is moderate quality evidence that multimedia education was more effective when added to a co-intervention (written information or brief standardised instructions provided by a health professional) compared with the co-intervention alone (MD of knowledge scores 24.59%, 95% CI 22.34 to 26.83, two studies with 381 participants).Skill acquisition: There is moderate quality evidence that multimedia education was more effective than usual care or no education (MD of inhaler technique score 18.32%, 95% CI 11.92 to 24.73, two studies with 94 participants) and written education (risk ratio (RR) of improved inhaler technique 2.14, 95% CI 1.33 to 3.44, two studies with 164 participants). There is very low quality evidence that multimedia education was equally effective as education by a health professional (MD of inhaler technique score -1.01%, 95% CI -15.75 to 13.72, three studies with 130 participants).Compliance with medications: There is moderate quality evidence that there was no difference between multimedia education and usual care or no education (RR of complying 1.02, 95% CI 0.96 to 1.08, two studies with 4552 participants).We could not determine the effect of multimedia education on other outcomes, including patient satisfaction, self-efficacy and health outcomes, due to an inadequate number of studies from which to draw conclusions. This review provides evidence that multimedia education about medications is more effective than usual care (non-standardised education provided by health professionals as part of usual clinical care) or no education, in improving both knowledge and skill acquisition. It also suggests that multimedia education is at least equivalent to other forms of education, including written education and education provided by a health professional. However, this finding is based on often low quality evidence from a small number of trials. Multimedia education about medications could therefore be considered as an adjunct to usual care but there is inadequate evidence to recommend it as a replacement for written education or education by a health professional. Multimedia education may be considered as an alternative to education provided by a health professional, particularly in settings where provision of detailed education by a health professional is not feasible. More studies evaluating multimedia educational interventions are required in order to increase confidence in the estimate of effect of the intervention.Conclusions regarding the effect of multimedia education were limited by the lack of information provided by study authors about the educational interventions, and variability in their content and quality. Studies testing educational interventions should provide detailed information about the interventions and comparators. Research is required to establish a framework that is specific for the evaluation of the quality of multimedia educational programs. Conclusions were also limited by the heterogeneity in the outcomes reported and the instruments used to measure them. Research is required to identify a core set of outcomes which should be measured when evaluating patient educational interventions. Future research should use consistent, reliable and validated outcome measures so that comparisons can be made between studies.

Obtaining informed consent from patients considering bunion surgery can be challenging. This study assessed the efficacy of a multimedia technology as an adjunct to the informed consent process. A prospective, cohort study was conducted involving 55 patients (7 males, 48 females) who underwent a standardized verbal discussion regarding bunion correction surgery followed by completion of a knowledge questionnaire. A multimedia educational program was then administered and the knowledge questionnaire repeated. Additional supplementary questions were then given regarding satisfaction with the multimedia program. Patients answered 74% questions correctly before the multimedia module compared with 94% after it (P < 0.0001). Patients rated the ease of understanding and the amount of information provided by the module highly. Eighty-four percent of patients considered that the multimedia tool performed as well as the treating surgeon. Multimedia technology is useful in enhancing patient knowledge regarding bunion surgery for the purposes of obtaining informed consent.

The paradigm of client/server computing is changing. The model of a server running a monolithic application and supporting clients at the desktop is giving way to a different model that blurs the line between client and server. We are on the verge of plunging into the next generation of computing technology--distributed object-oriented computing. This is not only a change in requirements but a change in opportunities, and requires a new way of thinking for Information System (IS) developers. The information system demands caused by global competition are requiring even more access to decision making tools. Simply, object-oriented technology has been developed to supersede the current design process of information systems which is not capable of handling next generation multimedia.

Designing high-quality interactive multimedia learning modules.

PubMed

Huang, Camillan

2005-01-01

Modern research has broadened scientific knowledge and revealed the interdisciplinary nature of the sciences. For today's students, this advance translates to learning a more diverse range of concepts, usually in less time, and without supporting resources. Students can benefit from technology-enhanced learning supplements that unify concepts and are delivered on-demand over the Internet. Such supplements, like imaging informatics databases, serve as innovative references for biomedical information, but could improve their interaction interfaces to support learning. With information from these digital datasets, multimedia learning tools can be designed to transform learning into an active process where students can visualize relationships over time, interact with dynamic content, and immediately test their knowledge. This approach bridges knowledge gaps, fosters conceptual understanding, and builds problem-solving and critical thinking skills-all essential components to informatics training for science and medicine. Additional benefits include cost-free access and ease of dissemination over the Internet or CD-ROM. However, current methods for the design of multimedia learning modules are not standardized and lack strong instructional design. Pressure from administrators at the top and students from the bottom are pushing faculty to use modern technology to address the learning needs and expectations of contemporary students. Yet, faculty lack adequate support and training to adopt this new approach. So how can faculty learn to create educational multimedia materials for their students? This paper provides guidelines on best practices in educational multimedia design, derived from the Virtual Labs Project at Stanford University. The development of a multimedia module consists of five phases: (1) understand the learning problem and the users needs; (2) design the content to harness the enabling technologies; (3) build multimedia materials with web style standards and human factors principles; (4) user testing; (5) evaluate and improve design.

Zimmerman, Alan P.

1997-02-01

Criminal offenders are increasingly administratively processed by automated multimedia information systems. During this processing, case and offender biographical data, mugshot photos, fingerprints and other valuable information and media are collected by law enforcement officers. As part of their criminal investigations, law enforcement officers are routinely called to solve criminal cases based upon limited evidence . . . evidence increasingly comprised of human DNA, ballistic casings and projectiles, chemical residues, latent fingerprints, surveillance camera facial images and voices. As multimedia systems receive greater use in law enforcement, traditional approaches used to index text data are not appropriate for images and signal data which comprise a multimedia database. Multimedia systems with integrated advanced pattern matching tools will provide law enforcement the ability to effectively locate multimedia information based upon content, without reliance upon the accuracy or completeness of text-based indexing.

Lu, Wenjun; Varna, Avinash L.; Wu, Min

2010-01-01

Digital multimedia such as images and videos are prevalent on today's internet and cause significant social impact, which can be evidenced by the proliferation of social networking sites with user generated contents. Due to the ease of generating and modifying images and videos, it is critical to establish trustworthiness for online multimedia information. In this paper, we propose novel approaches to perform multimedia forensics using compact side information to reconstruct the processing history of a document. We refer to this as FASHION, standing for Forensic hASH for informatION assurance. Based on the Radon transform and scale space theory, the proposed forensic hash is compact and can effectively estimate the parameters of geometric transforms and detect local tampering that an image may have undergone. Forensic hash is designed to answer a broader range of questions regarding the processing history of multimedia data than the simple binary decision from traditional robust image hashing, and also offers more efficient and accurate forensic analysis than multimedia forensic techniques that do not use any side information.

Toward visual user interfaces supporting collaborative multimedia content management

Husein, Fathi; Leissler, Martin; Hemmje, Matthias

2000-12-01

Supporting collaborative multimedia content management activities, as e.g., image and video acquisition, exploration, and access dialogues between naive users and multi media information systems is a non-trivial task. Although a wide variety of experimental and prototypical multimedia storage technologies as well as corresponding indexing and retrieval engines are available, most of them lack appropriate support for collaborative end-user oriented user interface front ends. The development of advanced user adaptable interfaces is necessary for building collaborative multimedia information- space presentations based upon advanced tools for information browsing, searching, filtering, and brokering to be applied on potentially very large and highly dynamic multimedia collections with a large number of users and user groups. Therefore, the development of advanced and at the same time adaptable and collaborative computer graphical information presentation schemes that allow to easily apply adequate visual metaphors for defined target user stereotypes has to become a key focus within ongoing research activities trying to support collaborative information work with multimedia collections.

Multimedia analysis has focused on images, video, and to some extent audio and has made progress in single channels excluding text. Visual analytics has focused on the user interaction with data during the analytic process plus the fundamental mathematics and has continued to treat text as did its precursor, information visualization. The general problem we address in this tutorial is the combining of multimedia analysis and visual analytics to deal with multimedia information gathered from different sources, with different goals or objectives, and containing all media types and combinations in common usage.

Multimedia based health information to parents in a pediatric acute ward: a randomized controlled trial.

2013-12-01

To determine whether multimedia based health information presented to parents of children with breathing difficulties in a pediatric acute ward, is more effective than verbal information, to reduce parental anxiety and increase satisfaction. This randomized controlled trial was conducted in a pediatric acute ward in Norway, from January to March 2011. Parents were randomly assigned to a multimedia intervention (n=53), or verbal health information (n=48). Primary outcome measure was parental anxiety, and secondary outcome measures were parental satisfaction with nursing care and health information. Parental anxiety decreased from arrival to discharge within both groups. At discharge the anxiety levels in the intervention group were no lower than in the control group. There was no difference in satisfaction with nursing care between the groups, but parents in the intervention group reported higher satisfaction with the health information given in the acute ward (p=.005). Multimedia based health information did not reduce anxiety more than verbal information, among parents to children with breathing difficulties. However, after discharge the parents were more satisfied with the multimedia approach. More research is needed to recommend the use of multimedia based information as a routine to parents in pediatric emergency care. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Access to the world wide web and multimedia content is an important aspect of life. We present a web browser and a multimedia user interface adapted for control with a brain-computer interface (BCI) which can be used by severely motor impaired persons. The web browser dynamically determines the most efficient P300 BCI matrix size to select the links on the current website. This enables control of the web browser with fewer commands and smaller matrices. The multimedia player was based on an existing software. Both applications were evaluated with a sample of ten healthy participants and three end-users. All participants used a visual P300 BCI with face-stimuli for control. The healthy participants completed the multimedia player task with 90% accuracy and the web browsing task with 85% accuracy. The end-users completed the tasks with 62% and 58% accuracy. All healthy participants and two out of three end-users reported that they felt to be in control of the system. In this study we presented a multimedia application and an efficient web browser implemented for control with a BCI. Both applications provide access to important areas of modern information retrieval and entertainment. Copyright © 2014 Elsevier B.V. All rights reserved.

Chen, C. Y. Roger; Meliksetian, Dikran S.; Chang, Martin C.

1996-01-01

In this paper we discuss how classroom instruction can benefit from state-of-the-art technologies in networks, worldwide web access through Internet, multimedia, databases, and computing. Functional requirements for establishing such a high-tech classroom are identified, followed by descriptions of our current experimental implementations. The focus of the paper is on the capabilities of distributed collaboration, which supports both synchronous multimedia information sharing as well as a shared work environment for distributed teamwork and group decision making. Our ultimate goal is to achieve the concept of 'living world in a classroom' such that live and dynamic up-to-date information and material from all over the world can be integrated into classroom instruction on a real-time basis. We describe how we incorporate application developments in a geography study tool, worldwide web information retrievals, databases, and programming environments into the collaborative system.

The Internet and education in surgery.

PubMed

Veldenz, H C; Dennis, J W

1998-09-01

The purpose of this review is to explain the developing role of the Internet and the World Wide Web (WWW) in promoting education in surgery. Internet sites relevant to surgery are appearing rapidly. Remote literature searches can query for surgery trials and results. Societies are using the WWW for transmission and review of publication materials. News groups interactively discuss current developments and trends. Surgeons are using personal and institutional sites to advertise services. Conventional slide shows migrate to the WWW for convenient downloading for surgeons and patients. Multimedia capabilities of the WWW expand the depth of information transmission, enabling education emanating from remote sites with narration and video depiction of procedures. These sophisticated tools can be demonstrated today with real online applications. One site facilitates surgical education using the WWW for program information, symposium coordination, links to regional subspecialty societies, residency cataloging, patient question and answer forums, and multimedia procedure descriptions. The principles of WWW communication used in this website can adapt to meet any educational need. The specialty of surgery is well suited to incorporation of online multimedia education over the Internet to follow new developments in our field.

Exploring context and content links in social media: a latent space method.

PubMed

Qi, Guo-Jun; Aggarwal, Charu; Tian, Qi; Ji, Heng; Huang, Thomas S

2012-05-01

Social media networks contain both content and context-specific information. Most existing methods work with either of the two for the purpose of multimedia mining and retrieval. In reality, both content and context information are rich sources of information for mining, and the full power of mining and processing algorithms can be realized only with the use of a combination of the two. This paper proposes a new algorithm which mines both context and content links in social media networks to discover the underlying latent semantic space. This mapping of the multimedia objects into latent feature vectors enables the use of any off-the-shelf multimedia retrieval algorithms. Compared to the state-of-the-art latent methods in multimedia analysis, this algorithm effectively solves the problem of sparse context links by mining the geometric structure underlying the content links between multimedia objects. Specifically for multimedia annotation, we show that an effective algorithm can be developed to directly construct annotation models by simultaneously leveraging both context and content information based on latent structure between correlated semantic concepts. We conduct experiments on the Flickr data set, which contains user tags linked with images. We illustrate the advantages of our approach over the state-of-the-art multimedia retrieval techniques.

Innovative Multimedia for Teaching Nematology

PubMed Central

Eisenback, J. D.

1993-01-01

The availability of interactive multimedia authoring software programs promises to revolutionize the teaching of nematology. These programs integrate text, hypertext, graphics, animations, video, and sound. The user interacts with the information on demand in a nonlinear fashion. Beginning students can limit themselves to the general outlines of the subject, and advanced students can explore the information to the limits of their ability. Use of interactive multimedia does not eliminate the need for effective, enthusiastic teachers but provides a mechanism for the efficient transfer of information. An interactive multimedia presentation that supplements lectures in an introductory course is presented as an example of the application of this technology for teaching nematology. PMID:19279782

To determine patient recall of specific risks associated with endoscopic sinus surgery and whether an adjunct multimedia education module is an effective patient tool in enhancing the standard informed consent process. Prospective, randomized, controlled trial. Fifty consecutive adult patients scheduled for endoscopic sinus surgery at a rhinology clinic of a tertiary care hospital were recruited for this study. Informed consent was studied by comparing the number of risks recalled when patients had a verbal discussion in conjunction with a 6-minute interactive module or the verbal discussion alone. Early recall was measured immediately following the informed consent process, and delayed recall was measured 3 to 4 weeks after patient preference details were also collected. Early risk recall in the multimedia group was significantly higher than the control group (P = .0036); however, there was no difference between the groups in delayed risk recall. Seventy-six percent of participants expressed interest in viewing the multimedia module if available online between the preoperative and procedural day. Sixty-eight percent of patients preferred having the multimedia module as an adjunct to the informed consent process as opposed to the multimedia consent process alone. There is an early improvement in overall risk recall in patients who complete an interactive multimedia module, with a clear patient preference for this method. Here we emphasize the well-known challenges of patient education and demonstrate the effectiveness of integrating technology into clinical practice in order to enhance the informed consent process. 1b Laryngoscope, 126:1273-1278, 2016. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Analysts who work with collections of multimedia to perform information foraging understand how difficult it is to connect information across diverse sets of mixed media. The wealth of information from blogs, social media, and news sites often can provide actionable intelligence; however, many of the tools used on these sources of content are not capable of multimedia analysis because they only analyze a single media type. As such, analysts are taxed to keep a mental model of the relationships among each of the media types when generating the broader content picture. To address this need, we have developed Canopy, amore » novel visual analytic tool for analyzing multimedia. Canopy provides insight into the multimedia data relationships by exploiting the linkages found in text, images, and video co-occurring in the same document and across the collection. Canopy connects derived and explicit linkages and relationships through multiple connected visualizations to aid analysts in quickly summarizing, searching, and browsing collected information to explore relationships and align content. In this paper, we will discuss the features and capabilities of the Canopy system and walk through a scenario illustrating how this system might be used in an operational environment.

To evaluate the effectiveness of an accessibility-enhanced multimedia informational educational programme in reducing anxiety and increasing satisfaction with the information and materials received by patients undergoing cardiac catheterisation. Cardiac catheterisation is one of the most anxiety-provoking invasive procedures for patients. However, informational education using multimedia to inform patients undergoing cardiac catheterisation has not been extensively explored. A randomised experimental design with three-cohort prospective comparisons. In total, 123 consecutive patients were randomly assigned to one of three groups: regular education; (group 1), accessibility-enhanced multimedia informational education (group 2) and instructional digital videodisc education (group 3). Anxiety was measured with Spielberger's State Anxiety Inventory, which was administered at four time intervals: before education (T0), immediately after education (T1), before cardiac catheterisation (T2) and one day after cardiac catheterisation (T3). A satisfaction questionnaire was administrated one day after cardiac catheterisation. Data were collected from May 2009-September 2010 and analysed using descriptive statistics, chi-squared tests, one-way analysis of variance, Scheffe's post hoc test and generalised estimating equations. All patients experienced moderate anxiety at T0 to low anxiety at T3. Accessibility-enhanced multimedia informational education patients had significantly lower anxiety levels and felt the most satisfied with the information and materials received compared with patients in groups 1 and 3. A statistically significant difference in anxiety levels was only found at T2 among the three groups (p = 0·004). The findings demonstrate that the accessibility-enhanced multimedia informational education was the most effective informational educational module for informing patients about their upcoming cardiac catheterisation, to reduce anxiety and improve satisfaction with the information and materials received compared with the regular education and instructional digital videodisc education. As the accessibility-enhanced multimedia informational education reduced patient anxiety and improved satisfaction with the information and materials received, it can be adapted to complement patient education in future regular cardiac care. © 2013 John Wiley & Sons Ltd.

Innovating information-delivery for potential clinical trials participants. What do patients want from multi-media resources?

PubMed

Shneerson, Catherine; Windle, Richard; Cox, Karen

2013-01-01

To discover whether the provision of clinical trials information via a multi-media platform could better meet the needs, preferences and practices of potential cancer trial participants. A mixed qualitative and quantitative questionnaire was delivered to 72 participants from cancer support groups to elicit views on the provision and design features of multimedia resources in delivering clinical trials information. Perceived lack of information is an expressed barrier to clinical trials participation. Multimedia resources were viewed positively as a way to address this barrier by most potential clinical trials participants; in particular by helping to align information to individual needs, promote active engagement with information, and by allowing more control of the learning experience. Whilst text remained the most valued attribute of any resource, other highly rated attributes included the resource being simple to use, easily accessible, having a clear focus, incorporating examples and visual aids, and being interactive. Provision of support for the learning resource was also rated highly. As in other areas, such as education, multimedia resources may enhance the delivery and acceptance of information regarding clinical trials. Better alignment of information may have a positive impact on recruitment and retention into clinical trials. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

To assess whether a multimedia-assisted preoperative informed consent procedure has an effect on patients' knowledge concerning cataract surgery, satisfaction with the informed consent process, and reduction in anxiety levels. Hietzing Hospital, Vienna, Austria. Prospective randomized controlled clinical trial. Patients participated in an informed consent procedure for age-related cataract surgery that included the standard approach only (reading the information brochure and having a standardized face-to-face discussion) or supplemented with a computer-animated video. The main outcome was information retention assessed by a questionnaire. Further outcome measures used were the State-Trait Anxiety Inventory, the Visual Function-14 score, and an assessment of satisfaction. The study included 123 patients (64 in standard-only group; 59 in computer-animated video group). Both groups scored well on the questionnaire; however, patients who watched the video performed better (82% retention versus 72%) (P = .002). Scores tended to decrease with increasing age (r = -0.25, P = .005); however, this decrease was smaller in the group that watched the video. Both groups had elevated anxiety levels (means in video group: anxiety concerning the current situation [S-anxiety] = 63.8 ± 9.6 [SD], general tendency toward anxiety [T-anxiety] = 65.5 ± 7.9; means in control group: S-anxiety = 61.9 ± 10.3, T-anxiety = 66.2 ± 7.8). A high level of information retention was achieved using an informed consent procedure consisting of an information brochure and a standardized face-to-face discussion. A further increase in information retention was achieved, even with increasing patient age, by adding a multimedia presentation.

MacCann, Carolyn; Lievens, Filip; Libbrecht, Nele; Roberts, Richard D

2016-11-01

People process emotional information using visual, vocal, and verbal cues. However, emotion management is typically assessed with text based rather than multimedia stimuli. This study (N = 427) presents the new multimedia emotion management assessment (MEMA) and compares it to the text-based assessment of emotion management used in the MSCEIT. The text-based and multimedia assessment showed similar levels of cognitive saturation and similar prediction of relevant criteria. Results demonstrate that the MEMA scores have equivalent evidence of validity to the text-based MSCEIT test scores, demonstrating that multimedia assessment of emotion management is viable. Furthermore, our results inform the debate as to whether cognitive saturation in emotional intelligence (EI) measures represents "noise" or "substance". We find that cognitive ability associations with EI represent substantive variance rather than construct-irrelevant shared variance due to reading comprehension ability required for text-based items.

International guidelines recommend the use of appropriate informed consent procedures in low literacy research settings because written information is not known to guarantee comprehension of study information. This study developed and evaluated a multimedia informed consent tool for people with low literacy in an area where a malaria treatment trial was being planned in The Gambia. We developed the informed consent document of the malaria treatment trial into a multimedia tool integrating video, animations and audio narrations in three major Gambian languages. Acceptability and ease of use of the multimedia tool were assessed using quantitative and qualitative methods. In two separate visits, the participants' comprehension of the study information was measured by using a validated digitised audio questionnaire. The majority of participants (70%) reported that the multimedia tool was clear and easy to understand. Participants had high scores on the domains of adverse events/risk, voluntary participation, study procedures while lowest scores were recorded on the question items on randomisation. The differences in mean scores for participants' 'recall' and 'understanding' between first and second visits were statistically significant (F (1,41)=25.38, p<0.00001 and (F (1, 41) = 31.61, p<0.00001 respectively. Our locally developed multimedia tool was acceptable and easy to administer among low literacy participants in The Gambia. It also proved to be effective in delivering and sustaining comprehension of study information across a diverse group of participants. Additional research is needed to compare the tool to the traditional consent interview, both in The Gambia and in other sub-Saharan settings.

Application-oriented architecture for multimedia teleservices

NASA Astrophysics Data System (ADS)

Vanrijssen, Erwin; Widya, Ing; Michiels, Eddie

This paper looks into communications capabilities that are required by distributed multimedia applications to achieve relation preserving information exchange. These capabilities are derived by analyzing the notion of 'information exchange' and are embodied in communications functionalities. To emphasize the importance of the users' view, a top-down approach is applied. The revised Open Systems Interconnection (OSI) Application Layer Structure (OSI-ALS) is used to model the communications functionalities and to develop an architecture for composition of multimedia teleservices with these functionalities. This work may therefore be considered an exercise to evaluate the suitability of OSI-ALS for composition of multimedia teleservices.

2012-06-01

Obtaining "informed consent" is an integral aspect of surgery that can be fraught with difficulty. This study assessed the efficacy of a multimedia education tool in improving patients' understanding when used as an adjunct to the traditional verbal consent process regarding ankle lateral ligament reconstruction surgery. A total of 56 patients (28 males and 28 females) were recruited with a mean age of 36 years. A standardized verbal discussion regarding surgical treatment was provided to each patient. Understanding was then assessed using a knowledge questionnaire. Subsequently, each patient observed a multimedia educational program following which the knowledge questionnaire was repeated. Additional supplementary questions were then given regarding the ease of understanding and satisfaction with the 2 methods of education delivery. The patients answered 75% of the questions correctly before the multimedia module compared with 88% after it (P < .001). Patients rated the ease of understanding and the amount of information provided by the module highly (9.5 cm and 9.0 cm on a 10-cm Visual Analogue Scale scale, respectively), and 61% of patients considered that the multimedia tool performed as well as the treating surgeon. Multimedia tools used in sequence after a verbal consent resulted in improved patient understanding of pertinent information regarding ankle lateral ligament reconstruction surgery.

Simon, Christian M; Klein, David W; Schartz, Helen A

2016-01-01

The potential of interactive multimedia to improve biobank informed consent has yet to be investigated. The aim of this study was to test the separate effectiveness of interactivity and multimedia at improving participant understanding and confidence in understanding of informed consent compared with a standard, face-to-face (F2F) biobank consent process. A 2 (face-to-face versus multimedia) × 2 (standard versus enhanced interactivity) experimental design was used with 200 patients randomly assigned to receive informed consent. All patients received the same information provided in the biobank's nine-page consent document. Interactivity (F(1,196) = 7.56, P = 0.007, partial η(2) = 0.037) and media (F(1,196) = 4.27, P = 0.04, partial η(2) = 0.021) independently improved participants' understanding of the biobank consent. Interactivity (F(1,196) = 6.793, P = 0.01, partial η(2) = 0.033), but not media (F(1,196) = 0.455, not significant), resulted in increased participant confidence in their understanding of the biobank's consent materials. Patients took more time to complete the multimedia condition (mean = 18.2 min) than the face-to-face condition (mean = 12.6 min). This study demonstrated that interactivity and multimedia each can be effective at promoting an individual's understanding and confidence in their understanding of a biobank consent, albeit with additional time investment. Researchers should not assume that multimedia is inherently interactive, but rather should separate the two constructs when studying electronic consent.

Wireless Multimedia Sensor Networks (WMSNs) have emerged and shifted the focus from the typical scalar wireless sensor networks to networks with multimedia devices that are capable to retrieve video, audio, images, as well as scalar sensor data. WMSNs are able to deliver multimedia content due to the availability of inexpensive CMOS cameras and microphones coupled with the significant progress in distributed signal processing and multimedia source coding techniques. In this paper, we outline the design challenges of WMSNs, give a comprehensive discussion of the proposed architectures, algorithms and protocols for the different layers of the communication protocol stack for WMSNs, and evaluate the existing WMSN hardware and testbeds. The paper will give the reader a clear view of the state of the art at all aspects of this research area, and shed the light on its main current challenges and future trends. We also hope it will foster discussions and new research ideas among its researchers. PMID:22163571

It also proved to be effective in delivering and sustaining comprehension of study information across a diverse group of participants. Additional research is needed to compare the tool to the traditional consent interview, both in The Gambia and in other sub-Saharan settings. PMID:25133065

Clinicians and researchers are increasingly using technology-based behavioral health interventions to improve intervention effectiveness and to reach underserved populations. However, these interventions are rarely informed by evidence-based findings of how technology can be optimized to promote acquisition of key skills and information. At the same time, experts in multimedia learning generally do not apply their findings to health education or conduct research in clinical contexts. This paper presents an overview of some key aspects of multimedia learning research that may allow those developing health interventions to apply informational technology with the same rigor as behavioral science content. We synthesized empirical multimedia learning literature from 1992 to 2011. We identified key findings and suggested a framework for integrating technology with educational and behavioral science theory. A scientific, evidence-driven approach to developing technology-based interventions can yield greater effectiveness, improved fidelity, increased outcomes, and better client service.

1995-01-01

This paper reviews the studies which were undertaken jointly by Telesat and Industry Canada to provide an estimate of the market opportunities for residential multi-media services in the rural and small urban areas of Canada. This study is part of the Advanced Satcom program, a Ka-band satellite system proposal which is currently in the implementation proposal phase by the government and the Canadian space industry of which Telesat is an active member. Advanced Satcom extends the reach of terrestrial information highways to the remote and sparsely populated parts of the country in a cost-effective manner and thus provides a ubiquitous coverage of the information highways to all Canadians. Therefore, the rural and small urban markets are believed to be good opportunities for the Advanced Satcom. Although the results are primarily intended for fixed residential applications, they can also be used as input to market opportunity studies for wideband mobile applications.

Although the Mars Exploration Rovers, Mars Reconnaissance Orbiter, and Mars Odyssey Missions set the standard for science communication and public education about Mars, the Phoenix Mission was presented with robust new communication challenges and opportunities. The new frontier includes Web 2.0, international forums, internal and external blogs, social networking sites, as well as the traditional media and education outlets for communicating science and information. We will explore the highlights and difficulties of managing the 'message from Mars' in our current multimedia saturated world while balancing authentic science discoveries, public expectations, and communication demands. Our goal is to create a more science savvy public and a more communication oriented science community for the future. The key issues are helping the public and our scientists distinguish between information and knowledge and managing the content that connects the two.

The complexity of cardiac surgery requires continuous training, education and information addressing different individuals: physicians (cardiac surgeons, residents, anaesthesiologists, cardiologists), medical students, perfusionists and patients. Efficacy and efficiency of education and training will likely be improved by the use of multimedia information systems. Nevertheless, computer-based education is facing some serious disadvantages: 1) multimedia productions require tremendous financial and time resources; 2) the obtained multimedia data are only usable for one specific target user group in one specific instructional context; 3) computer based learning programs often show deficiencies in the support of individual learning styles and in providing individual information adjusted to the learner's individual needs. In this paper we describe a computer-system, providing multiple re-use of multimedia-data in different instructional sceneries and providing flexible composition of content to different target user groups. The ZYX document model has been developed, allowing the modelling and flexible on-the-fly composition of multimedia fragments. It has been implemented as a DataBlade module into the object-relational database system Informix Dynamic Server and allows for presentation-neutral storage of multimedia content from the application domain, delivery and presentation of multimedia material, content based retrieval, re-use and composition of multimedia material for different instructional settings. Multimedia data stored in the repository, that can be processed and authored in terms of our identified needs is created by using a next generation authoring environment called CardioOP-Wizard. High-quality intra-operative video is recorded using a video-robot. Difficult surgical procedures are visualized with generic and CT-based 3D-animations. An on-line architecture for multiple re-use and flexible composition of media data has been established. The system contains the following instructional applications (prototypically implemented): a multimedia textbook on operative techniques, an interactive module for problem based-training, a module for creation and presentation of lectures and a module for patient information. Principles of cognitive psychology and knowledge management have been employed in the program. These instructional applications provide information ranging from basic knowledge at the beginner's level, procedural knowledge for the advanced level to implicit knowledge for the professional level. For media-annotation with meta-data a metainformation system, the CardioOP-Clas has been developed. The prototype focuses on aortocoronary bypass grafting and heart transplantation. The demonstrated system reflects an integrated approach in terms of information technology and teaching by means of multiple re-use and composition of stored media-items to the individual user and the chosen educational setting on different instructional levels.

To assess the effectiveness of a multimedia informed consent tool for adults participating in a clinical trial in the Gambia. Adults eligible for inclusion in a malaria treatment trial (n = 311) were randomized to receive information needed for informed consent using either a multimedia tool (intervention arm) or a standard procedure (control arm). A computerized, audio questionnaire was used to assess participants' comprehension of informed consent. This was done immediately after consent had been obtained (at day 0) and at subsequent follow-up visits (days 7, 14, 21 and 28). The acceptability and ease of use of the multimedia tool were assessed in focus groups. On day 0, the median comprehension score in the intervention arm was 64% compared with 40% in the control arm (P = 0.042). The difference remained significant at all follow-up visits. Poorer comprehension was independently associated with female sex (odds ratio, OR: 0.29; 95% confidence interval, CI: 0.12-0.70) and residing in Jahaly rather than Basse province (OR: 0.33; 95% CI: 0.13-0.82). There was no significant independent association with educational level. The risk that a participant's comprehension score would drop to half of the initial value was lower in the intervention arm (hazard ratio 0.22, 95% CI: 0.16-0.31). Overall, 70% (42/60) of focus group participants from the intervention arm found the multimedia tool clear and easy to understand. A multimedia informed consent tool significantly improved comprehension and retention of consent information by research participants with low levels of literacy.

Web usability, if evaluation done correctly, can significantly improve the quality of the website. Website containing multimedia for education shoud apply user interfaces that are both easy to learn and easy to use. Multimedia has big role in changing the mindset of a person in learning. Using multimedia, learners get easy to obtain information, adjust information and empower information. Therefore, multimedia is utilized by teachers in developing learning techniques to improve student learning outcomes. For students with self-directed learning, multimedia provides the ease and completeness of the courses in such a way that students can complete the learning independently both at school and at home without the guidance of teachers. The learning independence takes place in how students choose, absorb information, and follow the evaluation quickly and efficiently. The 2013 Curriculum 2013 for Vocational High School (SMK) requires teachers to create engaging teaching and learning activities that students enjoy in the classroom (also called invitation learning environment). The creation of learning activity environment is still problem for most teachers. Various researches reveal that teaching and learning activities will be more effective and easy when assisted by visual tools. Using multimedia, learning material can be presented more attractively that help students understand the material easily. The opposite is found in the learning activity environment who only rely on ordinary lectures. Usability is a quality level of multimedia with easy to learn, easy to use and encourages users to use it. The website Multimedia Interactive Learning for Mathematics SMK Class X is targeted object. Usability website in Multimedia Interactive Learning for Mathematics SMK Class X is important indicators to measure effectiveness, efficiency, and student satisfaction to access the functionality of website. This usability measurement should be done carefully before the design is implemented thoroughly. The only way to get test with high quality results is to start testing at the beginning of the design process and continuously testing each of the next steps. This research performs usability testing on of website by using WAMMI criterion (Website Analysis and Measurement Inventory) and will be focused on how convenience using the website application. Components of Attractiveness, Controllability, Efficiency, Helpfulness, and Learnability are applied. The website in Multimedia Interactive Learning for Mathematics SMK Class X can be in accordance with the purpose to be accepted by student to improve student learning outcomes. The results show that WAMMI method show the usability value of Multimedia Mathematics SMK Class X is about from 70% to 90%.

Interactive visual comparison of multimedia data through type-specific views

Analysts who work with collections of multimedia to perform information foraging understand how difficult it is to connect information across diverse sets of mixed media. The wealth of information from blogs, social media, and news sites often can provide actionable intelligence; however, many of the tools used on these sources of content are not capable of multimedia analysis because they only analyze a single media type. As such, analysts are taxed to keep a mental model of the relationships among each of the media types when generating the broader content picture. To address this need, we have developed Canopy, a novel visual analytic tool for analyzing multimedia. Canopy provides insight into the multimedia data relationships by exploiting the linkages found in text, images, and video co-occurring in the same document and across the collection. Canopy connects derived and explicit linkages and relationships through multiple connected visualizations to aid analysts in quickly summarizing, searching, and browsing collected information to explore relationships and align content. In this paper, we will discuss the features and capabilities of the Canopy system and walk through a scenario illustrating how this system might be used in an operational environment.

Static multimedia on the Web can already be hardly structured manually. Although unavoidable and necessary, manual annotation of dynamic multimedia becomes even less feasible when multimedia quickly changes in complexity, i.e. in volume, modality, and usage context. The latter context could be set by learning or other purposes of the multimedia material. This multimedia dynamics calls for categorisation systems that index, query and retrieve multimedia objects on the fly in a similar way as a human expert would. We present and demonstrate such a supervised dynamic multimedia object categorisation system. Our categorisation system comes about by continuously gauging it to a group of human experts who annotate raw multimedia for a certain domain ontology given a usage context. Thus effectively our system learns the categorisation behaviour of human experts. By inducing supervised multi-modal content and context-dependent potentials our categorisation system associates field strengths of raw dynamic multimedia object categorisations with those human experts would assign. After a sufficient long period of supervised machine learning we arrive at automated robust and discriminative multimedia categorisation. We demonstrate the usefulness and effectiveness of our multimedia categorisation system in retrieving semantically meaningful soccer-video fragments, in particular by taking advantage of multimodal and domain specific information and knowledge supplied by human experts.

The combination of new and rapidly developing interactive multimedia computers and applications with electronic networks will require a restructuring of our traditional approach to strategic planning and organizational structure. Worldwide telecommunication networks (using satellites, cable) are now facilitating the global pooling of healthcare information and medical knowledge independent of location. The development of multimedia information and communication systems demands cooperative working teams of authors, who are able to master several areas of medical knowledge as well as the presentation of these in different multimedia forms. The assemblage of telematics and services offers a base for multimedia applications, for example teleteaching, telelearning, telepublishing, teleconsulting, teleconferencing, telemedicine etc. The expansion of the internet will also lead to the formation of interdisciplinary "Global Education Networks". The theory and practice of education are undergoing dramatic changes. Lifelong learning and adaptation of medical practice to new knowledge and new techniques will be even more important in the future.

Joint Attributes and Event Analysis for Multimedia Event Detection.

PubMed

Ma, Zhigang; Chang, Xiaojun; Xu, Zhongwen; Sebe, Nicu; Hauptmann, Alexander G

2017-06-15

Semantic attributes have been increasingly used the past few years for multimedia event detection (MED) with promising results. The motivation is that multimedia events generally consist of lower level components such as objects, scenes, and actions. By characterizing multimedia event videos with semantic attributes, one could exploit more informative cues for improved detection results. Much existing work obtains semantic attributes from images, which may be suboptimal for video analysis since these image-inferred attributes do not carry dynamic information that is essential for videos. To address this issue, we propose to learn semantic attributes from external videos using their semantic labels. We name them video attributes in this paper. In contrast with multimedia event videos, these external videos depict lower level contents such as objects, scenes, and actions. To harness video attributes, we propose an algorithm established on a correlation vector that correlates them to a target event. Consequently, we could incorporate video attributes latently as extra information into the event detector learnt from multimedia event videos in a joint framework. To validate our method, we perform experiments on the real-world large-scale TRECVID MED 2013 and 2014 data sets and compare our method with several state-of-the-art algorithms. The experiments show that our method is advantageous for MED.

Currently, security is a critical factor for multimedia services running in the cloud computing environment. As an effective mechanism, trust can improve security level and mitigate attacks within cloud computing environments. Unfortunately, existing scheduling strategy for multimedia service in the cloud computing environment do not integrate trust mechanism when making scheduling decisions. In this paper, we propose a scheduling scheme for multimedia services in multi clouds. At first, a novel scheduling architecture is presented. Then, We build a trust model including both subjective trust and objective trust to evaluate the trust degree of multimedia service providers. By employing Bayesian theory, the subjective trust degree between multimedia service providers and users is obtained. According to the attributes of QoS, the objective trust degree of multimedia service providers is calculated. Finally, a scheduling algorithm integrating trust of entities is proposed by considering the deadline, cost and trust requirements of multimedia services. The scheduling algorithm heuristically hunts for reasonable resource allocations and satisfies the requirement of trust and meets deadlines for the multimedia services. Detailed simulated experiments demonstrate the effectiveness and feasibility of the proposed trust scheduling scheme.

Evaluation of new multimedia formats for cancer communications.

Providing quality, current cancer information to cancer patients and their families is a key function of the National Cancer Institute (NCI) Web site. This information is now provided in predominantly-text format, but could be provided in formats using multimedia, including animation and sound. Since users have many choices about where to get their information, it is important to provide the information in a format that is helpful and that they prefer. To pilot and evaluate multimedia strategies for future cancer-information program formats for lay users, the National Cancer Institute created new multimedia versions of existing text programs. We sought to evaluate user performance and preference on these 3 new formats and on the 2 existing text formats. The National Cancer Institute's "What You Need to Know About Lung Cancer" program was the test vehicle. There were 5 testing sessions, 1 dedicated to each format. Each session lasted about 1 hour, with 9 participants per session and 45 users overall. Users were exposed to the assigned cancer program from beginning to end in 1 of 5 formats: text paperback booklet, paperback booklet formatted in HTML on the Web, spoken audio alone, spoken audio synchronized with a text Web page, and Flash multimedia (animation, spoken audio, and text). Immediately thereafter, the features and design of the 4 alternative formats were demonstrated in detail. A multiple-choice pre-test and post-test quiz on the cancer content was used to assess user learning (performance) before and after experiencing the assigned program. The quiz was administered using an Authorware software interface writing to an Access database. Users were asked to rank from 1 to 5 their preference for the 5 program formats, and provide structured and open-ended comments about usability of the 5 formats. Significant improvement in scores from pre-test to post-test was seen for the total study population. Average scores for users in each of the 5 format groups improved significantly. Increments in improvement, however, were not statistically different between any of the format groups. Significant improvements in quiz scores were seen irrespective of age group or education level. Of the users, 71.1% ranked the Flash program first among the 5 formats, and 84.4% rated Flash as their first or second choice. Audio was the least-preferred format, ranking fifth among 46.7% of users and first among none. Flash was ranked first among users regardless of education level, age group, or format group to which the user was assigned. Under the pilot study conditions, users overwhelmingly preferred the Flash format to the other 4 formats. Learning occurred equally in all formats. Use of multimedia should be considered as communication strategies are developed for updating cancer content and attracting new users.

Multimedia psychoeducational interventions to support patient self-care in degenerative conditions: A realist review.

PubMed

O'Halloran, Peter; Scott, David; Reid, Joanne; Porter, Sam

2015-10-01

Multimedia interventions are increasingly used to deliver information in order to promote self-care among patients with degenerative conditions. We carried out a realist review of the literature to investigate how the characteristics of multimedia psychoeducational interventions combine with the contexts in which they are introduced to help or hinder their effectiveness in supporting self-care for patients with degenerative conditions. Electronic databases (Medline, Science Direct, PSYCHinfo, EBSCO, and Embase) were searched in order to identify papers containing information on multimedia psychoeducational interventions. Using a realist review approach, we reviewed all relevant studies to identify theories that explained how the interventions work. Ten papers were included in the review. All interventions sought to promote self-care behaviors among participants. We examined the development and content of the multimedia interventions and the impact of patient motivation and of the organizational context of implementation. We judged seven studies to be methodologically weak. All completed studies showed small effects in favor of the intervention. Multimedia interventions may provide high-quality information in an accessible format, with the potential to promote self-care among patients with degenerative conditions, if the patient perceives the information as important and develops confidence about self-care. The evidence base is weak, so that research is needed to investigate effective modes of delivery at different resource levels. We recommend that developers consider how an intervention will reduce uncertainty and increase confidence in self-care, as well as the impact of the context in which it will be employed.

Interactive multimedia consent for biobanking: A randomized trial

PubMed Central

Simon, Christian M.; Klein, David W.; Schartz, Helen A.

2015-01-01

Purpose Interactive multimedia’s potential to improve biobank informed consent has yet to be investigated. The aim of this study was to test the separate effectiveness of interactivity and multimedia at improving participant understanding and confidence of understanding of informed consent, compared to a standard, face-to-face (F2F) biobank consent process. Methods A 2 (F2F versus multimedia) × 2 (standard versus enhanced interactivity) experimental design was used with 200 patients randomly assigned to receive informed consent. All patients received the same information provided in the Biobank’s 9-page consent document. Results Interactivity (F(1,196)=7.56, p=0.007, partial η2=0.037) and Media (F(1,196)=4.27, p=0.04, partial η2=0.021) independently improved participants’ understanding of the Biobank consent. Interactivity (F(1,196) = 6.793, p = 0.01, partial η2=0.033), but not Media (F(1,196) = 0.455, n.s.), resulted in increased participant confidence in their understanding of the Biobank’s consent. Patients took more time to complete the multimedia (M=18.2 min.) than the F2F (M=12.6 min.) conditions. Conclusion This study demonstrated that interactivity and multimedia each can be effective at promoting individuals’ understanding and confidence in understanding of a biobank consent, albeit with additional time investment. Researchers should not assume that multimedia is inherently interactive, but rather separate the two constructs when studying electronic consent. PMID:25834945

Dynamic storage in resource-scarce browsing multimedia applications

NASA Astrophysics Data System (ADS)

Elenbaas, Herman; Dimitrova, Nevenka

1998-10-01

In the convergence of information and entertainment there is a conflict between the consumer's expectation of fast access to high quality multimedia content through narrow bandwidth channels versus the size of this content. During the retrieval and information presentation of a multimedia application there are two problems that have to be solved: the limited bandwidth during transmission of the retrieved multimedia content and the limited memory for temporary caching. In this paper we propose an approach for latency optimization in information browsing applications. We proposed a method for flattening hierarchically linked documents in a manner convenient for network transport over slow channels to minimize browsing latency. Flattening of the hierarchy involves linearization, compression and bundling of the document nodes. After the transfer, the compressed hierarchy is stored on a local device where it can be partly unbundled to fit the caching limits at the local site while giving the user availability to the content.

Multimedia is making an increasingly significant contribution to our informational society. The usefulness of this technology is already evident in education, business presentations, informational kiosks (e.g., in museums), training and the entertainment environment. Institutions, from grade schools to medical schools, are exploring the use of multifaceted electronic text books and teaching aids to enhance course materials. Through multimedia, teachers and students can take full advantage of the cognitive value of animation, audio, video and other types in a seamless application. The Software Technology Branch at NASA Johnson Space Center (NASA/JSC) is taking similar approaches to apply the state-of-the-art technology to space training, mission operations and other applications. This paper discusses the characteristics and development of multimedia applications at the NASA/JSC.

Design of novel non-contact multimedia controller for disability by using visual stimulus.

PubMed

Pan, Jeng-Shyang; Lo, Chi-Chun; Tsai, Shang-Ho; Lin, Bor-Shyh

2015-12-01

The design of a novel non-contact multimedia controller is proposed in this study. Nowadays, multimedia controllers are generally used by patients and nursing assistants in the hospital. Conventional multimedia controllers usually involve in manual operation or other physical movements. However, it is more difficult for the disabled patients to operate the conventional multimedia controller by themselves; they might totally depend on others. Different from other multimedia controllers, the proposed system provides a novel concept of controlling multimedia via visual stimuli, without manual operation. The disabled patients can easily operate the proposed multimedia system by focusing on the control icons of a visual stimulus device, where a commercial tablet is used as the visual stimulus device. Moreover, a wearable and wireless electroencephalogram (EEG) acquisition device is also designed and implemented to easily monitor the user's EEG signals in daily life. Finally, the proposed system has been validated. The experimental result shows that the proposed system can effectively measure and extract the EEG feature related to visual stimuli, and its information transfer rate is also good. Therefore, the proposed non-contact multimedia controller exactly provides a good prototype of novel multimedia controlling scheme. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Interpreting the Hydrology of a Desert Mountain Stream to a General Public: Using Multimedia to Enhance Informal Experiential Education

NASA Astrophysics Data System (ADS)

Woodard, G. C.; Carpenter, K. D.

2002-12-01

Sabino Canyon near Tucson, Arizona draws over 1 million visits per year. The centerpiece of the canyon is Sabino Creek, an ephemeral stream fed by seasonal snowmelt and monsoon rains. Frequently asked questions by canyon visitors include: How can a stream flow in the desert environment? Why are the surrounding mountaintops so much cooler and wetter? How can the stream flow without recent rain or snowmelt? Where does the water go? The NSF STC for Sustainability of semi-Arid Hydrology and Riparian Areas (SAHRA) has partnered with the USGS and the USDA Forest Service to develop static displays and a touch-screen electronic kiosk for the Sabino Canyon Visitors Center that explain what streamflow is, where the waters of Sabino Creek originate, where they go, what conditions produce flash flooding, and the hydrology of sky island environments. The kiosk, and an associated Web site, also give current weather and streamflow conditions at various points in the canyon, plus typical and extreme conditions for the current date. Designing displays that attract and inform a diverse mix of visitors with varying levels of interest, reading levels, and attention spans is a major challenge. We have integrated static displays featuring light boxes with a touch-screen kiosk featuring graphics, animation, video, sound effects, and voice-overs. Optional sub-titles are in five languages. The goal is to attract visitors to the display and then meet their various interests and information needs. Hydrology is a foreign subject to the great majority of people, and opportunities to informally educate them are relatively scarce. This presentation will show how current multimedia technology can be combined with proven methods of informal experiential education to communicate some basic hydrologic principles.

The impact of presentation style on the retention of online health information: a randomized-controlled experiment.

PubMed

Frisch, Anne-Linda; Camerini, Luca; Schulz, Peter J

2013-01-01

The Internet plays an increasingly important role in health education, providing laypeople with information about health-related topics that range from disease-specific contexts to general health promotion. Compared to traditional health education, the Internet allows the use of multimedia applications that offer promise to enhance individuals' health knowledge and literacy. This study aims at testing the effect of multimedia presentation of health information on learning. Relying on an experimental design, it investigates how retention of information differs for text-only presentation, image-only presentation, and multimedia (text and image) presentation of online health information. Two hundred and forty students were randomly assigned to four groups each exposed to a different website version. Three groups were exposed to the same information using text only, image only, or text and image presentation. A fourth group received unrelated information (control group). Retention was assessed by the means of a recognition test. To examine a possible interaction between website version and recognition test, half of the students received a recognition test in text form and half of them received a recognition test in imagery form. In line with assumptions from Dual Coding Theory, students exposed to the multimedia (text and image) presentation recognized significantly more information than students exposed to the text-only presentation. This did not hold for students exposed to the image-only presentation. The impact of presentation style on retention scores was moderated by the way retention was assessed for image-only presentation, but not for text-only or multimedia presentation. Possible explanations and implications for the design of online health education interventions are discussed.

2000-05-01

Advertising in TV broadcasting has shown that multimedia is a very effective means to present merchandise and attract shoppers. This has been applied to the Web by including animated multimedia banner ads on web pages. However, the issues of coupling interactive browsing, shopping, and secure transactions e.g. from inside a multimedia banner, have only recently started to being explored. Currently there is an explosively growing amount of back-end services available (e.g., business to business commerce (B2B), business to consumer (B2C) commerce, and infomercial services) in the Internet. These services are mostly accessible through static HTML web pages at a few specific web portals. In this paper, we will investigate the feasibility of using interactive multimedia banners as pervasive access point for the B2C, B2B, and infomercial services. We present a system architecture that involves a layer of middleware agents functioning as the bridge between the interactive multimedia banners and back-end services.

Byszewski, Anna; Bezzina, Kathryn; Latrous, Meriem

2017-01-01

For optimal direction in career paths and postgraduate training, students can benefit from information to guide them through options. Using geriatric medicine as a template, the goal was to develop a multimedia podcast resource that can give a clearer picture of what a specialty entails. The project included a survey of existing resources and needs assessment of medical students at the University of Ottawa, Canada. This survey assessed students' knowledge of geriatrics and interest in the field and explored what they foresee as being important to be informed on when considering application to programs. Based on this, interview questions and content were developed for a podcast which was then evaluated. Interviews were conducted with physicians and residents nationwide. Relevant resources and links were added to the podcast. Evaluation demonstrated improved student understanding and interest in geriatric medicine as a career. Point-by-point format for a template on how to develop similar podcasts was developed to assist other specialties looking to develop similar information. As no such framework currently exists, results of this project can serve as a template for other postgraduate programs in developing a multimedia resource for informing prospective trainees.

Comparing Feedback Types in Multimedia Learning of Speech by Young Children With Common Speech Sound Disorders: Research Protocol for a Pretest Posttest Independent Measures Control Trial.

PubMed

Doubé, Wendy; Carding, Paul; Flanagan, Kieran; Kaufman, Jordy; Armitage, Hannah

2018-01-01

Children with speech sound disorders benefit from feedback about the accuracy of sounds they make. Home practice can reinforce feedback received from speech pathologists. Games in mobile device applications could encourage home practice, but those currently available are of limited value because they are unlikely to elaborate "Correct"/"Incorrect" feedback with information that can assist in improving the accuracy of the sound. This protocol proposes a "Wizard of Oz" experiment that aims to provide evidence for the provision of effective multimedia feedback for speech sound development. Children with two common speech sound disorders will play a game on a mobile device and make speech sounds when prompted by the game. A human "Wizard" will provide feedback on the accuracy of the sound but the children will perceive the feedback as coming from the game. Groups of 30 young children will be randomly allocated to one of five conditions: four types of feedback and a control which does not play the game. The results of this experiment will inform not only speech sound therapy, but also other types of language learning, both in general, and in multimedia applications. This experiment is a cost-effective precursor to the development of a mobile application that employs pedagogically and clinically sound processes for speech development in young children.

2009-02-01

Performing information retrieval tasks while preserving data confidentiality is a desirable capability when a database is stored on a server maintained by a third-party service provider. This paper addresses the problem of enabling content-based retrieval over encrypted multimedia databases. Search indexes, along with multimedia documents, are first encrypted by the content owner and then stored onto the server. Through jointly applying cryptographic techniques, such as order preserving encryption and randomized hash functions, with image processing and information retrieval techniques, secure indexing schemes are designed to provide both privacy protection and rank-ordered search capability. Retrieval results on an encrypted color image database and security analysis of the secure indexing schemes under different attack models show that data confidentiality can be preserved while retaining very good retrieval performance. This work has promising applications in secure multimedia management.

A multimedia patient education program on colorectal cancer screening increases knowledge and willingness to consider screening among Hispanic/Latino patients.

2009-08-01

To test a multimedia patient education program on colorectal cancer (CRC) screening that was designed specifically for the Hispanic/Latino community, and developed with input from community members. A total of 270 Hispanic/Latino adults, age 50-80 years, participated in Spanish for all phases of this pretest-posttest design. Patients were randomly assigned to a version of the multimedia program that opened with either a positive or negative introductory appeal. Structured interviews assessed screening relevant knowledge (anatomy and key terms, screening options, and risk information), past screening behavior, willingness to consider screening options, intention to discuss CRC screening with the doctor, and reactions to the multimedia patient education program. The multimedia program significantly increased knowledge of anatomy and key terms (e.g., polyp), primary screening options (FOBT, flexible sigmoidoscopy, colonoscopy), and risk information as well as willingness to consider screening (p<.001 for all). No significant differences emerged between positive and negative introductory appeals on these measures, intention to discuss CRC screening with their doctor, or rating the multimedia program. Multimedia tools developed with community input that are designed to present important health messages using graphics and audio can reach Hispanic/Latino adults across literacy levels and ethnic backgrounds. Additional research is needed to determine effects on actual screening behavior. Despite promising results for engaging a difficult-to-reach audience, the multimedia program should not be considered a stand-alone intervention or a substitute for communication with physicians. Rather, it is a priming mechanism intended to prepare patients for productive discussions of CRC screening.

2012-08-01

To describe processes used to develop a multi-media psycho-educational intervention to prepare patients for a discussion about cancer clinical trials (CTs). Guided by a Steering Committee, formative research was conducted to develop an informative and engaging tool about cancer CTs. Twenty-three patients and caregivers participated in formative in-depth interviews to elicit information about perceptions of cancer CTs to inform production of a new media product. Formative research revealed participants had concerns about experimentation, held beliefs that cancer CTs were for patients who had no other treatment options, and wanted a balance of information about pros and cons of CT participation. The value of physicians as credible spokespersons and the use of patients as role-models were supported. Using iterative processes, the production team infused the results into creation of a multimedia psycho-educational intervention titled Clinical Trials: Are they Right for You? An intervention, developed through an iterative consumer-focused process involving multiple stakeholders and formative research, may result in an engaging informative product. If found to be efficacious, Clinical Trials: Are they Right for You? is a low-cost and easily disseminated multimedia psycho-educational intervention to assist cancer patients with making an informed decision about cancer CTs.

A solid and versatile communications platform is very important in modern Ambient Intelligence (AmI) applications, which usually require the transmission of large amounts of multimedia information over a highly heterogeneous network. This article focuses on the concept of Process-in-Network (PIN), which is defined as the possibility that the network processes information as it is being transmitted, and introduces a more comprehensive approach than current network processing technologies. PIN can take advantage of waiting times in queues of routers, idle processing capacity in intermediate nodes, and the information that passes through the network. PMID:22969390

Murtagh, Fionn; Guillaume, Damien

Information search and retrieval has become by nature a distributed task. We look at tools and techniques which are of importance in this area. Current technological evolution can be summarized as the growing stability and cohesiveness of distributed architectures of searchable objects. The objects themselves are more often than not multimedia, including published articles or grey literature reports, yellow page services, image data, catalogs, presentation and online display materials, and ``operations'' information such as scheduling and publicly accessible proposal information. The evolution towards distributed architectures, protocols and formats, and the direction of our own work, are focussed on in this paper.

Currently, museums provide their visitors with interactive tour guide applications that can be installed in mobile devices and provide timely tailor-made multimedia information about exhibits on display. In this paper, we argue that mobile devices not only could provide help to visitors, but also to museum staff. Our goal is to integrate, within the same system, multimedia tour guides with the management facilities required by museums. In this paper, we present iMuseumA (intelligent museum with agents), a mobile-based solution to customize visits and perform context-aware management tasks. iMuseumA follows an agent-based approach, which makes it possible to interact easily with the museum environment and make decisions based on its current status. This system is currently deployed in the Museum of Informatics at the Informatics School of the University of Málaga, and its main contributions are: (i) a mobile application that provides management facilities to museum staff by means of sensing and processing environmental data; (ii) providing an integrated solution for visitors, tour guides and museum staff that allows coordination and communication enrichment among different groups of users; (iii) using and benefiting from group communication for heterogeneous groups of users that can be created on demand.

Music is a way of expressing our feelings and emotions. Suitable music can positively affect people. However, current multimedia control methods, such as manual selection or automatic random mechanisms, which are now applied broadly in MP3 and CD players, cannot adaptively select suitable music according to the user's physiological state. In this study, a brain computer interface-based smart multimedia controller was proposed to select music in different situations according to the user's physiological state. Here, a commercial mobile tablet was used as the multimedia platform, and a wireless multi-channel electroencephalograph (EEG) acquisition module was designed for real-time EEG monitoring. A smart multimedia control program built in the multimedia platform was developed to analyze the user's EEG feature and select music according his/her state. The relationship between the user's state and music sorted by listener's preference was also examined in this study. The experimental results show that real-time music biofeedback according a user's EEG feature may positively improve the user's attention state.

The informed consent is a legal requirement prior to surgery and should be based on an extensive preoperative interview. Multimedia productions can therefore be utilised as supporting tool. In a prospective randomised trial, we evaluated the impact of an extended education on patients undergoing cholecystectomy. For extended patient information, a professionally built DVD was used. After randomisation to either the DVD or the control group, patients were informed with or without additional presentation of the DVD. The quality of education was evaluated using a purpose-built questionnaire. One hundred fourteen patients were included in the DVD and 98 in the control group. Patient characteristics did not differ significantly despite a higher educational level in the DVD group. The score of correctly answered questions was higher in the DVD group (19.88 vs. 17.58 points, p < 0.001). As subgroup analysis revealed, particular patient characteristics additionally impacted on results. Patients should be informed the most extensively prior to any surgical procedure. Multimedia productions therefore offer a suitable instrument. In the presented study, we could prove the positive impact of an information DVD on patients knowledge. Nevertheless, multimedia tools cannot replace personal interaction and should only be used to support daily work.

Multimedia elements add value to text documents by transmitting information difficult to express in words. In healthcare, many professional and services keep this elements in their own repositories. This brings the problem of information fragmentation in different silos which hinder its access to other healthcare professionals. On the other hand patients have clinical data of their own in different formats generated in different healthcare organizations which is not accessible to professionals within our healthcare network. This paper describes the design, development and implementation processes of a service which allows media elements to be loaded in a patient clinical data repository (CDR) either through an electronic health record by professionals (EHR) or through a personal health record (PHR) by patients, in order to avoid fragmentation of the information.

Background: The presence of Online Support Groups (OSG) is expected to empower patients with infertility, thus allowing patients to be the focus of healthcare services. This study will evaluate multimedia content, OSG, and utilization of information for decision-making by patients using infertility services. This study is a mixed method study conducted from January - June 2016 at Yasmin IVF Clinic, Dr. Cipto Mangunkusumo General Hospital; and SMART IVF Clinic, Jakarta. The subjects are patients with infertility who sought treatment at the clinics. Data was collected through a structured interview in the form of a questionnaire. Informed consent was obtained from all individual participants included in the study. All procedures that performed in studies were by the ethical standards of the institutional. The result from 72 respondents showed quantitative analysis did not reveal any association between multimedia and OSG information sources with patient knowledge regarding infertility management. However, qualitative analysis highlighted three issues: the information regarding infertility services in the available multimedia and the OSG; use of the available information by patients when deciding to use infertility services. The level of awareness of respondents on searching information regarding infertility on the clinic website is still limited. It happened because most of the patients in the clinic are unaware of clinic website existence which provided the infertility information. Therefore, the clinic website needs to be promoted so the usage of this website will increase in the future.

The difficulty of understanding programming concept is a major problem in basic programming lessons. Based on the results of preliminary studies, 60% of students reveal the monotonous of learning process caused by the limited number of media. Children Learning in Science (CLIS) method was chosen as solution because CLIS has facilitated students’ initial knowledge to be optimized into conceptual knowledge. Technological involvement in CLIS (gamification) helped students to understand basic programming concept. This research developed a media using CLIS method with gamification elements to increase the excitement of learning process. This research declared that multimedia is considered good by students, especially regarding the mechanical aspects of multimedia, multimedia elements and aspects of multimedia information structure. Multimedia gamification learning with the CLIS model showed increased number of students’ concept understanding.

PIRIA: a general tool for indexing, search, and retrieval of multimedia content

The Internet is a continuously expanding source of multimedia content and information. There are many products in development to search, retrieve, and understand multimedia content. But most of the current image search/retrieval engines, rely on a image database manually pre-indexed with keywords. Computers are still powerless to understand the semantic meaning of still or animated image content. Piria (Program for the Indexing and Research of Images by Affinity), the search engine we have developed brings this possibility closer to reality. Piria is a novel search engine that uses the query by example method. A user query is submitted to the system, which then returns a list of images ranked by similarity, obtained by a metric distance that operates on every indexed image signature. These indexed images are compared according to several different classifiers, not only Keywords, but also Form, Color and Texture, taking into account geometric transformations and variance like rotation, symmetry, mirroring, etc. Form - Edges extracted by an efficient segmentation algorithm. Color - Histogram, semantic color segmentation and spatial color relationship. Texture - Texture wavelets and local edge patterns. If required, Piria is also able to fuse results from multiple classifiers with a new classification of index categories: Single Indexer Single Call (SISC), Single Indexer Multiple Call (SIMC), Multiple Indexers Single Call (MISC) or Multiple Indexers Multiple Call (MIMC). Commercial and industrial applications will be explored and discussed as well as current and future development.

Diagrams increase the recall of nondepicted text when understanding is also increased.

Serra, Michael J

2010-02-01

Multimedia presentations typically produce better memory and understanding than do single-medium presentations. Little research, however, has considered the effect of multimedia on memory for nonmultimedia information within a large multimedia presentation (e.g., nondepicted text in a large text with diagrams). To this end, the present two experiments compared memory for target text information that was either depicted in diagrams or not. Participants (n = 180) studied either a text-only version of a text about lightning or a text-with-diagrams version in which half the target information was depicted in diagrams. Memory was tested with both free recall and cued recall questions. Overall, diagrams did not affect memory for the entire text; diagrams increased memory only for the information they depicted. Diagrams exerted a generalized effect on free recall only when diagrams increased the overall understanding of the text (i.e., when the participants studied the materials twice before the test).

Multimedia is often utilized by teachers to present a learning materials. Learning that delivered by multimedia enables people to understand the information of up to 60% of the learning in general. To applying the creative learning to the classroom, multimedia presentation needs a laboratory as a space that provides multimedia needs. This study aims to reveal the level of student acceptance on the multimedia laboratories, by explaining the direct and indirect effect of internal support and technology infrastructure. Technology Acceptance Model (TAM) is used as the basis of measurement on this research, through the perception of usefulness, ease of use, and the intention, it’s recognized capable of predicting user acceptance about technology. This study used the quantitative method. The data analysis using path analysis that focuses on trimming models, it’s performed to improve the model of path analysis structure by removing exogenous variables that have insignificant path coefficients. The result stated that Internal Support and Technology Infrastructure are well mediated by TAM variables to measure the level of technology acceptance. The implications suggest that TAM can measure the success of multimedia laboratory utilization in Faculty of Engineering UNIMA.

Psychiatric practice is becoming increasingly more complex in terms of the available treatment options, use of new technologies for assessments, and a need for psychiatric patients and their caregivers to be familiar with general medical procedures. This trend will only intensify in the years to come. Routine methods of providing information relevant to clinical decision making about healthcare evaluations or management are often suboptimal. Relatively little research has been done on enhancing the capacity of psychiatric patients and the caregivers to make truly informed decisions about management. In this paper, we review studies that compared the effects of multimedia (video- or computer-based) educational aids with those of routine procedures to inform healthcare consumers about medical evaluations or management. Although most of these investigations were conducted in non-psychiatric patients, the results should be relevant for psychiatric practice of tomorrow. We searched MEDLINE, PsycINFO, and CINAHL bibliographic databases. Randomized controlled trials that used objective measures of knowledge or understanding of the information provided were selected. Studies were rated as positive if the multimedia educational aid resulted in a greater improvement in knowledge or understanding than the control condition. The quality of each study was also rated using a newly developed Scale for Assessing Scientific Quality of Investigations (SASQI). A total of 37 randomized controlled trials were identified. Nearly two-thirds of the studies (23/37) in diverse patient populations and for varied medical assessments and treatments reported that multimedia educational aids produced better understanding of information compared to routine methods. SASQI scores for the positive and negative studies were comparable, suggesting that lower quality was not related to positive findings. In conclusion, multimedia educational aids hold promise for improving the provision of complex medical information to patients and caregivers. It is likely that as psychiatric patients and their treating clinicians face increasingly complex choices regarding mental health treatment, multimedia decisional aids could become an effective supplement to the clinician patient interaction in near future.

This study describes the design of a real-time interactive multimedia teleradiology system and assesses how the system is used by referring physicians in point-of-care situations and supports or hinders aspects of physician-radiologist interaction. We developed a real-time multimedia teleradiology management system that automates the transfer of images and radiologists' reports and surveyed physicians to triangulate the findings and to verify the realism and results of the experiment. The web-based survey was delivered to 150 physicians from a range of specialties. The survey was completed by 72% of physicians. Data showed a correlation between rich interactivity, satisfaction, and effectiveness. The results of our experiments suggest that real-time multimedia teleradiology systems are valued by referring physicians and may have the potential for enhancing their practice and improving patient care and highlight the critical role of multimedia technologies to provide real-time multimode interactivity in current medical care.

2006-06-01

This paper describes the work being conducted in the domain of brain-computer interaction (BCI) at the Multimodal Interaction Group, Computer Vision and Multimedia Laboratory, University of Geneva, Geneva, Switzerland. The application focus of this work is on multimodal interaction rather than on rehabilitation, that is how to augment classical interaction by means of physiological measurements. Three main research topics are addressed. The first one concerns the more general problem of brain source activity recognition from EEGs. In contrast with classical deterministic approaches, we studied iterative robust stochastic based reconstruction procedures modeling source and noise statistics, to overcome known limitations of current techniques. We also developed procedures for optimal electroencephalogram (EEG) sensor system design in terms of placement and number of electrodes. The second topic is the study of BCI protocols and performance from an information-theoretic point of view. Various information rate measurements have been compared for assessing BCI abilities. The third research topic concerns the use of EEG and other physiological signals for assessing a user's emotional status.

We evaluated the effectiveness of an accessibility-enhanced multimedia informational educational program in reducing depression and anxiety increasing satisfaction with the information and materials received by patients in coronary care unit. We selected 100 patients from among the patients who stayed at or who underwent surgery at one of two ICUs for any reason who satisfied the eligibility criteria, and agreed to participate in the research. The participants were included in the control or experimental group by random selection. The patients completed the Hospital Anxiety Depression Scale during ICU admission and 1week after hospital discharge. The difference in HADSA score was significantly greater in patients who received education than in patients who did not receive multimedia nursing education (4.2±0.58 vs. 0.6±0.42; p<.01). Additionally, the difference in HADSD score was significantly greater in patients who received multimedia nursing education (2.2±0.53 vs. 0.64±0.46; p<.01). This study showed that anxiety and depression associated with hospital can be reduced with multimedia nursing education. Copyright © 2015 Elsevier Inc. All rights reserved.

2006-01-01

Recent advances in computing, communications and storage technology have made multimedia data become prevalent. Multimedia has gained enormous potential in improving the processes in a wide range of fields, such as advertising and marketing, education and training, entertainment, medicine, surveillance, wearable computing, biometrics, and remote sensing. Rich content of multimedia data, built through the synergies of the information contained in different modalities, calls for new and innovative methods for modeling, processing, mining, organizing, and indexing of this data for effective and efficient searching, retrieval, delivery, management and sharing of multimedia content, as required by the applications in the abovementioned fields. The objective of this paper is to present our views on the trends that should be followed when developing such methods, to elaborate on the related research challenges, and to introduce the new conference, Multimedia Content Analysis, Management and Retrieval, as a premium venue for presenting and discussing these methods with the scientific community. Starting from 2006, the conference will be held annually as a part of the IS&T/SPIE Electronic Imaging event.

Diaz, Juan R; Lloret, Jaime; Jimenez, Jose M; Sendra, Sandra

2014-01-01

Wireless Ad hoc networks provide a flexible and adaptable infrastructure to transport data over a great variety of environments. Recently, real-time audio and video data transmission has been increased due to the appearance of many multimedia applications. One of the major challenges is to ensure the quality of multimedia streams when they have passed through a wireless ad hoc network. It requires adapting the network architecture to the multimedia QoS requirements. In this paper we propose a new architecture to organize and manage cluster-based ad hoc networks in order to provide multimedia streams. Proposed architecture adapts the network wireless topology in order to improve the quality of audio and video transmissions. In order to achieve this goal, the architecture uses some information such as each node's capacity and the QoS parameters (bandwidth, delay, jitter, and packet loss). The architecture splits the network into clusters which are specialized in specific multimedia traffic. The real system performance study provided at the end of the paper will demonstrate the feasibility of the proposal.

Cell phone camera ballistics: attacks and countermeasures

Multimedia forensics deals with the analysis of multimedia data to gather information on its origin and authenticity. One therefore needs to distinguish classical criminal forensics (which today also uses multimedia data as evidence) and multimedia forensics where the actual case is based on a media file. One example for the latter is camera forensics where pixel error patters are used as fingerprints identifying a camera as the source of an image. Of course multimedia forensics can become a tool for criminal forensics when evidence used in a criminal investigation is likely to be manipulated. At this point an important question arises: How reliable are these algorithms? Can a judge trust their results? How easy are they to manipulate? In this work we show how camera forensics can be attacked and introduce a potential countermeasure against these attacks.

Music is a way of expressing our feelings and emotions. Suitable music can positively affect people. However, current multimedia control methods, such as manual selection or automatic random mechanisms, which are now applied broadly in MP3 and CD players, cannot adaptively select suitable music according to the user’s physiological state. In this study, a brain computer interface-based smart multimedia controller was proposed to select music in different situations according to the user’s physiological state. Here, a commercial mobile tablet was used as the multimedia platform, and a wireless multi-channel electroencephalograph (EEG) acquisition module was designed for real-time EEG monitoring. A smart multimedia control program built in the multimedia platform was developed to analyze the user’s EEG feature and select music according his/her state. The relationship between the user’s state and music sorted by listener’s preference was also examined in this study. The experimental results show that real-time music biofeedback according a user’s EEG feature may positively improve the user’s attention state. PMID:25756862

Multimedia information processing in the SWAN mobile networked computing system

Agrawal, Prathima; Hyden, Eoin; Krzyzanowsji, Paul; Srivastava, Mani B.; Trotter, John

1996-03-01

Anytime anywhere wireless access to databases, such as medical and inventory records, can simplify workflow management in a business, and reduce or even eliminate the cost of moving paper documents. Moreover, continual progress in wireless access technology promises to provide per-user bandwidths of the order of a few Mbps, at least in indoor environments. When combined with the emerging high-speed integrated service wired networks, it enables ubiquitous and tetherless access to and processing of multimedia information by mobile users. To leverage on this synergy an indoor wireless network based on room-sized cells and multimedia mobile end-points is being developed at AT&T Bell Laboratories. This research network, called SWAN (Seamless Wireless ATM Networking), allows users carrying multimedia end-points such as PDAs, laptops, and portable multimedia terminals, to seamlessly roam while accessing multimedia data streams from the wired backbone network. A distinguishing feature of the SWAN network is its use of end-to-end ATM connectivity as opposed to the connectionless mobile-IP connectivity used by present day wireless data LANs. This choice allows the wireless resource in a cell to be intelligently allocated amongst various ATM virtual circuits according to their quality of service requirements. But an efficient implementation of ATM in a wireless environment requires a proper mobile network architecture. In particular, the wireless link and medium-access layers need to be cognizant of the ATM traffic, while the ATM layers need to be cognizant of the mobility enabled by the wireless layers. This paper presents an overview of SWAN's network architecture, briefly discusses the issues in making ATM mobile and wireless, and describes initial multimedia applications for SWAN.

2013-02-01

To compare multimedia and standard consent, in respect to patient comprehension, anxiety, and satisfaction, for various surgical/interventional procedures. Electronic searches of PubMed, MEDLINE, Ovid, Embase, and Google Scholar were performed. Relevant articles were assessed by 2 independent reviewers. Comparative (randomized and nonrandomized control trials) studies of multimedia and standard consent for a variety of surgical/interventional procedures were included. Studies had to report on at least one of the outcome measures. Studies were reviewed by 2 independent investigators. The first investigator extracted all relevant data, and consensus of each extraction was performed by a second investigator to verify the data. Overall, this review suggests that the use of multimedia as an adjunct to conventional consent appears to improve patient comprehension. Multimedia leads to high patient satisfaction in terms of feasibility, ease of use, and availability of information. There is no conclusive evidence demonstrating a significant reduction in preoperative anxiety.

In a short period of time, the multimedia sector has quickly progressed trying to overcome the exigencies of the customers in terms of transfer speeds, storage memory, image quality, and functionalities. In order to cope with this stringent situation, different hardware devices have been developed as possible choices. Despite of the fact that not every device is apt for implementing the high computational demands associated to multimedia applications; reconfigurable architectures appear as ideal candidates to achieve these necessities. As a direct consequence, worldwide universities and industries have incremented their research activity into this area, generating an important know-how base. In order to sort all the information generated about this issue, this paper reviews the most recent reconfigurable architectures for multimedia applications. As a result, this paper establishes the benefits and drawbacks of the different dynamically reconfigurable architectures for multimedia applications according to their system-level design.

1991-01-01

The VA's hospital information system, the Decentralized Hospital Computer Program (DHCP), is an integrated system based on a powerful set of software tools with shared data accessible from any of its application modules. It includes many functionally specific application subsystems such as laboratory, pharmacy, radiology, and dietetics. Physicians need applications that cross these application boundaries to provide useful and convenient patient data. One of these multi-specialty applications, the DHCP Imaging System, integrates multimedia data to provide clinicians with comprehensive patient-oriented information. User requirements for cross-disciplinary image access can be studied to define needs for similar text data access. Integration approaches must be evaluated both for their ability to deliver patient-oriented text data rapidly and their ability to integrate multimedia data objects. Several potential integration approaches are described as they relate to the DHCP Imaging System.

Currently, museums provide their visitors with interactive tour guide applications that can be installed in mobile devices and provide timely tailor-made multimedia information about exhibits on display. In this paper, we argue that mobile devices not only could provide help to visitors, but also to museum staff. Our goal is to integrate, within the same system, multimedia tour guides with the management facilities required by museums. In this paper, we present iMuseumA (intelligent museum with agents), a mobile-based solution to customize visits and perform context-aware management tasks. iMuseumA follows an agent-based approach, which makes it possible to interact easily with the museum environment and make decisions based on its current status. This system is currently deployed in the Museum of Informatics at the Informatics School of the University of Málaga, and its main contributions are: (i) a mobile application that provides management facilities to museum staff by means of sensing and processing environmental data; (ii) providing an integrated solution for visitors, tour guides and museum staff that allows coordination and communication enrichment among different groups of users; (iii) using and benefiting from group communication for heterogeneous groups of users that can be created on demand.

Growing evidence supports the use of multimedia presentations for informing patients. Therefore, we supported preoperative education by adding a multimedia tool and examined the effects in a randomized controlled trial. We randomized German-speaking patients scheduled for radical prostatectomy at our center to receive either a multimedia-supported (MME) or a standard education (SE). Outcomes were measured in a structured interview. Primary outcome was patient satisfaction. In addition, we applied validated instruments to determine anxiety and measures of decision-making. Results were given by mean and standard deviation. For comparison of groups we used t test and chi-square test. For an explorative analysis we applied multivariate logistic regression. We randomized 203 patients to receive MME (n=102) or SE (n=101). Complete satisfaction with preoperative education was more frequent in the MME group (69 vs 52%, p=.016) and patients after MME reported more questions (5.7 vs 4.2, p=.018). There was no difference concerning the duration of talks and the number of recalled risks. However, perceived knowledge was higher after MME (1.3 vs 1.6, p=.037). Anxiety and measures of decision-making were comparable. Patients judged the multimedia tool very positive, and 74% of the MME group thought that their preoperative education had been superior to SE. Multimedia support should be considered worthwhile for improving the informed consent process before surgery (www.germanctr.de; DRKS00000096).

Learners misperceive the benefits of redundant text in multimedia learning.

PubMed

Fenesi, Barbara; Kim, Joseph A

2014-01-01

Research on metacognition has consistently demonstrated that learners fail to endorse instructional designs that produce benefits to memory, and often prefer designs that actually impair comprehension. Unlike previous studies in which learners were only exposed to a single multimedia design, the current study used a within-subjects approach to examine whether exposure to both redundant text and non-redundant text multimedia presentations improved learners' metacognitive judgments about presentation styles that promote better understanding. A redundant text multimedia presentation containing narration paired with verbatim on-screen text (Redundant) was contrasted with two non-redundant text multimedia presentations: (1) narration paired with images and minimal text (Complementary) or (2) narration paired with minimal text (Sparse). Learners watched presentation pairs of either Redundant + Complementary, or Redundant + Sparse. Results demonstrate that Complementary and Sparse presentations produced highest overall performance on the final comprehension assessment, but the Redundant presentation produced highest perceived understanding and engagement ratings. These findings suggest that learners misperceive the benefits of redundant text, even after direct exposure to a non-redundant, effective presentation.

2004-10-01

This study was to develop Web-based multimedia content for Physical Examination and Health Assessment. The multimedia content was developed based on Jung's teaching and learning structure plan model, using the following 5 processes : 1) Analysis Stage, 2) Planning Stage, 3) Storyboard Framing and Production Stage, 4) Program Operation Stage, and 5) Final Evaluation Stage. The web based multimedia content consisted of an intro movie, main page and sub pages. On the main page, there were 6 menu bars that consisted of Announcement center, Information of professors, Lecture guide, Cyber lecture, Q&A, and Data centers, and a site map which introduced 15 week lectures. In the operation of web based multimedia content, HTML, JavaScript, Flash, and multimedia technology (Audio and Video) were utilized and the content consisted of text content, interactive content, animation, and audio & video. Consultation with the experts in context, computer engineering, and educational technology was utilized in the development of these processes. Web-based multimedia content is expected to offer individualized and tailored learning opportunities to maximize and facilitate the effectiveness of the teaching and learning process. Therefore, multimedia content should be utilized concurrently with the lecture in the Physical Examination and Health Assessment classes as a vital teaching aid to make up for the weakness of the face-to- face teaching-learning method.

Immersive and interactive multimedia applications offer complementary study tools in anatomy as users can explore 3D models while obtaining information about the organ, tissue or part being explored. Haptics increases the sense of interaction with virtual objects improving user experience in a more realistic manner. Common eye studying tools are books, illustrations, assembly models, and more recently these are being complemented with mobile apps whose 3D capabilities, computing power and customers are increasing. The goal of this project is to develop a complementary eye anatomy and pathology study tool using deformable models within a multimedia application, offering the students the opportunity for exploring the eye from up close and within with relevant information. Validation of the tool provided feedback on the potential of the development, along with suggestions on improving haptic feedback and navigation.

Hispanic cancer patients are underrepresented in clinical trials; research suggests lack of knowledge and language barriers contribute to low accrual. Multimedia materials offer advantages to Hispanic populations because they have high acceptability, are easy to disseminate, and can be viewed with family. Hispanic cancer patients and caregivers participated in focus groups to aid in developing a Spanish-language multimedia intervention to educate Hispanic cancer patients about clinical trials. We explored the feasibility of delivering the intervention in medical oncology clinics. A total of 35 patients were randomized to either the multimedia intervention group (n = 18) or a control group (n = 17) who were asked to read the National Cancer Institute's Spanish-language clinical trials brochure. Self-reported data on knowledge about and attitudes toward clinical trials, self-efficacy for participating in a clinical trial, intention to participate in a clinical trial if asked, and receptivity to information about a clinical trial were collected at baseline and 10 days later. Delivery of the multimedia presentation in oncology clinics was feasible. The intervention group had more knowledge about clinical trials at follow-up than the control group; scores for intention to participate in a clinical trial by participants in the intervention group increased from 3.8 to 4.0 of a possible 5, but declined in the control group from 4.5 to 4.1. No statistically significant difference was detected between groups in scores for attitudes or self-efficacy for making a decision to participate in a clinical trial. Our sample size was inadequate to identify differences between the informational methods. Although all patients were asked about their willingness to participate in a clinical trial, this decision was hypothetical. In addition, the study was conducted with a sample of Spanish-speaking Hispanic cancer patients at a comprehensive cancer center in Florida. Thus, the results may not generalize to other Hispanic populations. In the pilot project, we demonstrated the feasibility of delivering multimedia information to patients in medical oncology clinics. Because delivery in a clinical setting was found to be feasible, a larger study should be conducted to evaluate the efficacy of the multimedia intervention with respect to promoting accrual of Hispanic patients to clinical trials.

Clinical decisions for improving motor function in patients both with disability as well as improving an athlete's performance are made through clinical and movement analysis. Currently, this analysis facilitates identifying abnormalities in a patient's motor function for a large amount of neuro-musculoskeletal pathologies. However definitively identifying the underlying cause or long-term consequences of a specific abnormality in the patient's movement pattern is difficult since this requires information from multiple sources and formats across different times and currently relies on the experience and intuition of the expert clinician. In addition, this data must be persistent for longitudinal outcomes studies. Therefore a multimedia ePR system integrating imaging informatics data could have a significant impact on decision support within this clinical workflow. We present the design and architecture of such an ePR system as well as the data types that need integration in order to develop relevant decision support tools. Specifically, we will present two data model examples: 1) A performance improvement project involving volleyball athletes and 2) Wheelchair propulsion evaluation of patients with disabilities. The end result is a new frontier area of imaging informatics research within rehabilitation engineering and biomechanics.

Proper cooperation between patient and dentist is of great help to make a good oral impression. However, patients are frequently confused when information is given through traditional verbal description. The present study compared the effectiveness of the multimedia information delivery ways with the traditional verbal manner on patients' understanding level in oral impression taking. The recruited 191 participating patients were randomly assigned to the control group (the verbal group) and two intervention groups (the video group and the picture group) according to the information delivery manner. After intervention, the patients' understanding degree was measured by questionnaire and performance evaluation of behavior feedback on the provided information quantitatively. Also, patients' self-assessment of satisfaction was interviewed by telephone. All data was analyzed by SPSS 14.0 software, and p≤0.05 was set as significant difference in advance. One-Way ANOVA and Chi-square showed there were no statistically significant differences in the mean age, gender composition, and educational level among the three groups (P>0.05). In both questionnaire assessment and performance evaluation, One-Way ANOVA followed by LSD indicate that the video group gained a higher score than the verbal group or the picture group (P<0.05). The questionnaire score in the picture group is significantly higher than in the control group (P<0.05), but no significant difference was shown between these two groups in patients' performance evaluation (P>0.05). Higher percentage of satisfaction was reported by patients in the two multimedia groups than that in the control group. Oral impression taking is a consecutive process that requires action cooperation between dentists and patients simultaneously. This particularity makes it more suitable for multimedia delivery. The delivery of tailored information using multimedia in this study was favored by most patients and could improve the degree of patient understanding of the oral impression taking procedures.

Optimal route discovery for soft QOS provisioning in mobile ad hoc multimedia networks

NASA Astrophysics Data System (ADS)

Huang, Lei; Pan, Feng

2007-09-01

In this paper, we propose an optimal routing discovery algorithm for ad hoc multimedia networks whose resource keeps changing, First, we use stochastic models to measure the network resource availability, based on the information about the location and moving pattern of the nodes, as well as the link conditions between neighboring nodes. Then, for a certain multimedia packet flow to be transmitted from a source to a destination, we formulate the optimal soft-QoS provisioning problem as to find the best route that maximize the probability of satisfying its desired QoS requirements in terms of the maximum delay constraints. Based on the stochastic network resource model, we developed three approaches to solve the formulated problem: A centralized approach serving as the theoretical reference, a distributed approach that is more suitable to practical real-time deployment, and a distributed dynamic approach that utilizes the updated time information to optimize the routing for each individual packet. Examples of numerical results demonstrated that using the route discovered by our distributed algorithm in a changing network environment, multimedia applications could achieve better QoS statistically.

In recent years there has been a growing interest in the use of multimedia mobile guides in museum environments. Mobile devices have the capabilities to detect the user context and to provide pieces of information suitable to help visitors discover and follow the logical and emotional connections that develop during the visit. In this scenario, location based services (LBS) currently represent an asset, and the choice of the technology to determine users' position, combined with the definition of methods that can effectively convey information, become key issues in the design process. In this work, we present Museum Assistant (MusA), a general framework for the development of multimedia interactive guides for mobile devices. Its main feature is a vision-based indoor positioning system that allows the provision of several LBS, from way-finding to the contextualized communication of cultural contents, aimed at providing a meaningful exploration of exhibits according to visitors' personal interest and curiosity. Starting from the thorough description of the system architecture, the article presents the implementation of two mobile guides, developed to respectively address adults and children, and discusses the evaluation of the user experience and the visitors' appreciation of these applications.

Payne, Perry W

2013-03-01

The National Plan to Address Alzheimer's Disease calls for a new relationship between researchers and members of the public. This relationship is one that provides research information to patients and allows patients to provide ideas to researchers. One way to describe it is a "bidirectional translational relationship." Despite the numerous sources of online and offline information about Alzheimer's disease, there is no information source which currently provides this interaction. This article proposes the creation an Alzheimer's research information source dedicated to monitoring Alzheimer's research literature and providing user friendly, publicly accessible summaries of data written specifically for a lay audience. This information source should contain comprehensive, updated, user friendly, publicly available, reviews of Alzheimer's research and utilize existing online multimedia/social networking tools to provide information in useful formats that help patients, caregivers, and researchers learn rapidly from one another.

Innovation in multimedia systems impacts on our society. For example surveillance camera systems combine video and audio information. Currently a new sensor for capturing fingerprint traces is being researched. It combines greyscale images to determine the intensity of the image signal, on one hand, and topographic information to determine fingerprint texture on a variety of surface materials, on the other. This research proposes new application areas which will be analyzed from a technical-legal view point. It assesses how technology design can promote legal criteria of German and European privacy and data protection. For this we focus on one technology goal as an example.

Energy-aware scheduling of surveillance in wireless multimedia sensor networks.

Wang, Xue; Wang, Sheng; Ma, Junjie; Sun, Xinyao

Wireless sensor networks involve a large number of sensor nodes with limited energy supply, which impacts the behavior of their application. In wireless multimedia sensor networks, sensor nodes are equipped with audio and visual information collection modules. Multimedia contents are ubiquitously retrieved in surveillance applications. To solve the energy problems during target surveillance with wireless multimedia sensor networks, an energy-aware sensor scheduling method is proposed in this paper. Sensor nodes which acquire acoustic signals are deployed randomly in the sensing fields. Target localization is based on the signal energy feature provided by multiple sensor nodes, employing particle swarm optimization (PSO). During the target surveillance procedure, sensor nodes are adaptively grouped in a totally distributed manner. Specially, the target motion information is extracted by a forecasting algorithm, which is based on the hidden Markov model (HMM). The forecasting results are utilized to awaken sensor node in the vicinity of future target position. According to the two properties, signal energy feature and residual energy, the sensor nodes decide whether to participate in target detection separately with a fuzzy control approach. Meanwhile, the local routing scheme of data transmission towards the observer is discussed. Experimental results demonstrate the efficiency of energy-aware scheduling of surveillance in wireless multimedia sensor network, where significant energy saving is achieved by the sensor awakening approach and data transmission paths are calculated with low computational complexity.

Managing the timely access of information is a major challenge facing law enforcement agencies. One of the areas of greatest need is that of the case management process. During the course of FY98, the Office of National Drug Control Policy (ONDCP), the Counterdrug Technology Assessment Center (CTAC), the Idaho National Engineering and Environmental Laboratory (INEEL), and the Criminal Investigative Bureau (CIB) of the state of Idaho, created a Northwest testbed to develop and integrate a multimedia case management system. A system was developed to assist investigators in tracking and maintaining investigative cases and improving access to internal and external data resources. In this paper, we discuss the results of our case management system development and the ability to present state and federal information incorporating object oriented and multimedia techniques. We then outline our plans for future research and development.

A Multimedia Approach to Lab Reporting via Computer Presentation Software

NASA Astrophysics Data System (ADS)

Jenkinson, Gregory T.; Fraiman, Ana

1999-02-01

The use of multimedia software presents a new way for the educator to gather and present information. In a laboratory report, students are required to gather and present data that are available from a wide variety of resources. In the past, this information was compiled into a hard-copy report, consisting merely of text and possibly two-dimensional graphics. Today, Northeastern Illinois University students use Podium, one of many multimedia presentation applications available on the market. These presentation applications offer a rich array of choices for the type and quantity of information to compile. This "paperless" implementation gives students the opportunity to create a lab report that is a network of ideas, cross-referenced with hyperlinks in a personal fashion that is logical for that particular student. The use of hyperlinks allows easy access to previously learned concepts that may be needed for future labs. This new technology allows students to make links of their own and to begin to see chemistry as an encompassing industry with connection to all disciplines of science.

Enhancing Multimedia Imbalanced Concept Detection Using VIMP in Random Forests.

PubMed

Sadiq, Saad; Yan, Yilin; Shyu, Mei-Ling; Chen, Shu-Ching; Ishwaran, Hemant

2016-07-01

Recent developments in social media and cloud storage lead to an exponential growth in the amount of multimedia data, which increases the complexity of managing, storing, indexing, and retrieving information from such big data. Many current content-based concept detection approaches lag from successfully bridging the semantic gap. To solve this problem, a multi-stage random forest framework is proposed to generate predictor variables based on multivariate regressions using variable importance (VIMP). By fine tuning the forests and significantly reducing the predictor variables, the concept detection scores are evaluated when the concept of interest is rare and imbalanced, i.e., having little collaboration with other high level concepts. Using classical multivariate statistics, estimating the value of one coordinate using other coordinates standardizes the covariates and it depends upon the variance of the correlations instead of the mean. Thus, conditional dependence on the data being normally distributed is eliminated. Experimental results demonstrate that the proposed framework outperforms those approaches in the comparison in terms of the Mean Average Precision (MAP) values.

Coupled auralization and virtual video for immersive multimedia displays

NASA Astrophysics Data System (ADS)

Henderson, Paul D.; Torres, Rendell R.; Shimizu, Yasushi; Radke, Richard; Lonsway, Brian

2003-04-01

The implementation of maximally-immersive interactive multimedia in exhibit spaces requires not only the presentation of realistic visual imagery but also the creation of a perceptually accurate aural experience. While conventional implementations treat audio and video problems as essentially independent, this research seeks to couple the visual sensory information with dynamic auralization in order to enhance perceptual accuracy. An implemented system has been developed for integrating accurate auralizations with virtual video techniques for both interactive presentation and multi-way communication. The current system utilizes a multi-channel loudspeaker array and real-time signal processing techniques for synthesizing the direct sound, early reflections, and reverberant field excited by a moving sound source whose path may be interactively defined in real-time or derived from coupled video tracking data. In this implementation, any virtual acoustic environment may be synthesized and presented in a perceptually-accurate fashion to many participants over a large listening and viewing area. Subject tests support the hypothesis that the cross-modal coupling of aural and visual displays significantly affects perceptual localization accuracy.

A multimedia retrieval framework based on semi-supervised ranking and relevance feedback.

PubMed

Yang, Yi; Nie, Feiping; Xu, Dong; Luo, Jiebo; Zhuang, Yueting; Pan, Yunhe

2012-04-01

We present a new framework for multimedia content analysis and retrieval which consists of two independent algorithms. First, we propose a new semi-supervised algorithm called ranking with Local Regression and Global Alignment (LRGA) to learn a robust Laplacian matrix for data ranking. In LRGA, for each data point, a local linear regression model is used to predict the ranking scores of its neighboring points. A unified objective function is then proposed to globally align the local models from all the data points so that an optimal ranking score can be assigned to each data point. Second, we propose a semi-supervised long-term Relevance Feedback (RF) algorithm to refine the multimedia data representation. The proposed long-term RF algorithm utilizes both the multimedia data distribution in multimedia feature space and the history RF information provided by users. A trace ratio optimization problem is then formulated and solved by an efficient algorithm. The algorithms have been applied to several content-based multimedia retrieval applications, including cross-media retrieval, image retrieval, and 3D motion/pose data retrieval. Comprehensive experiments on four data sets have demonstrated its advantages in precision, robustness, scalability, and computational efficiency.

Learning strategy preferences, verbal-visual cognitive styles, and multimedia preferences for continuing engineering education instructional design

NASA Astrophysics Data System (ADS)

Baukal, Charles Edward, Jr.

A literature search revealed very little information on how to teach working engineers, which became the motivation for this research. Effective training is important for many reasons such as preventing accidents, maximizing fuel efficiency, minimizing pollution emissions, and reducing equipment downtime. The conceptual framework for this study included the development of a new instructional design framework called the Multimedia Cone of Abstraction (MCoA). This was developed by combining Dale's Cone of Experience and Mayer's Cognitive Theory of Multimedia Learning. An anonymous survey of 118 engineers from a single Midwestern manufacturer was conducted to determine their demographics, learning strategy preferences, verbal-visual cognitive styles, and multimedia preferences. The learning strategy preference profile and verbal-visual cognitive styles of the sample were statistically significantly different than the general population. The working engineers included more Problem Solvers and were much more visually-oriented than the general population. To study multimedia preferences, five of the seven levels in the MCoA were used. Eight types of multimedia were compared in four categories (types in parantheses): text (text and narration), static graphics (drawing and photograph), non-interactive dynamic graphics (animation and video), and interactive dynamic graphics (simulated virtual reality and real virtual reality). The first phase of the study examined multimedia preferences within a category. Participants compared multimedia types in pairs on dual screens using relative preference, rating, and ranking. Surprisingly, the more abstract multimedia (text, drawing, animation, and simulated virtual reality) were preferred in every category to the more concrete multimedia (narration, photograph, video, and real virtual reality), despite the fact that most participants had relatively little prior subject knowledge. However, the more abstract graphics were only slightly preferred to the more concrete graphics. In the second phase, the more preferred multimedia types in each category from the first phase were compared against each other using relative preference, rating, and ranking and overall rating and ranking. Drawing was the most preferred multimedia type overall, although only slightly more than animation and simulated virtual reality. Text was a distant fourth. These results suggest that instructional content for continuing engineering education should include problem solving and should be highly visual.

Shariff, Umar; Seretis, Charalampos; Lee, Doreen; Balasubramanian, Saba P

2016-06-01

Multimedia is an educational resource that can be used to supplement surgical skills training. The aim of this review was to determine the role of multimedia in surgical training and assessment by performing a systematic review of the literature. A systematic review for published articles was conducted on the following databases: PubMed/MEDLINE (1992 to November 2014), SCOPUS (1992 to November 2014) and EMBASE (1992 to November 2014). For each study the educational content, study design, surgical skill assessed and outcomes were recorded. A standard data extraction form was created to ensure systematic retrieval of relevant information. 21 studies were included; 14 randomized controlled trials (RCTs) and 7 non-randomized controlled trials (Non-RCTs). Technical skills were assessed in 7 RCTs and 3 non-RCTs; cognitive skills were assessed in 9 RCTs and 4 non-RCTs. In controlled studies, multimedia was associated with significant improvement in technical skills (4 studies; 4 RCTs) and cognitive skills (7 studies; 6 RCTs). In two studies multimedia was inferior in comparison to conventional teaching. Evaluation of multimedia (9 studies) demonstrated strongly favourable results. This review suggests that multimedia effectively facilitates both technical and cognitive skills acquisition and is well accepted as an educational resource.

Shaw, S. L.; Knipping, E.; Kumar, N.

2010-12-01

The presence of nitrogenous compounds can impact biogeochemical processes in the atmosphere, oceans and freshwater, and land surfaces. As a result, a number of regulations exist that are intended to control the amount and forms of nitrogen present in the environment. These range from the newly proposed Transport Rule, both the primary and secondary National Ambient Air Quality Standards (NAAQS) for nitrogen oxide targeted at ozone and particulate matter formation and nitrogen deposition, and waterbody requirements such as the Total Maximum Daily Load. This talk will cover a subset of research activities at EPRI that inform environmental nitrogen concerns. A multimedia modeling framework has facilitated effect studies of atmospheric loadings on ecosystems. Improvements in emissions estimates, such as for mobile sources, suggest large current underestimates that will substantially impact air quality modeling of nitrogen oxides. Analyses of wintertime nitrate formation in the northern U.S. are demonstrating the roles of NH3 and NOx in particle formation there. Novel measurements of power plant stack emissions suggest operating configurations can influence the isotopic composition of emitted NOx. Novel instruments for ambient measurements of nitrogen, and suggestions for improved deposition estimates, are being developed. EPRI results suggest that multimedia solutions across multiple economic sectors, such as electrification of a wide variety of engines and water quality treatment and trading, have the potential to improve environmental quality effectively.

A Compositional Relevance Model for Adaptive Information Retrieval

Mathe, Nathalie; Chen, James; Lu, Henry, Jr. (Technical Monitor)

1994-01-01

There is a growing need for rapid and effective access to information in large electronic documentation systems. Access can be facilitated if information relevant in the current problem solving context can be automatically supplied to the user. This includes information relevant to particular user profiles, tasks being performed, and problems being solved. However most of this knowledge on contextual relevance is not found within the contents of documents, and current hypermedia tools do not provide any easy mechanism to let users add this knowledge to their documents. We propose a compositional relevance network to automatically acquire the context in which previous information was found relevant. The model records information on the relevance of references based on user feedback for specific queries and contexts. It also generalizes such information to derive relevant references for similar queries and contexts. This model lets users filter information by context of relevance, build personalized views of documents over time, and share their views with other users. It also applies to any type of multimedia information. Compared to other approaches, it is less costly and doesn't require any a priori statistical computation, nor an extended training period. It is currently being implemented into the Computer Integrated Documentation system which enables integration of various technical documents in a hypertext framework.

MediaNet: a multimedia information network for knowledge representation

NASA Astrophysics Data System (ADS)

Benitez, Ana B.; Smith, John R.; Chang, Shih-Fu

2000-10-01

In this paper, we present MediaNet, which is a knowledge representation framework that uses multimedia content for representing semantic and perceptual information. The main components of MediaNet include conceptual entities, which correspond to real world objects, and relationships among concepts. MediaNet allows the concepts and relationships to be defined or exemplified by multimedia content such as images, video, audio, graphics, and text. MediaNet models the traditional relationship types such as generalization and aggregation but adds additional functionality by modeling perceptual relationships based on feature similarity. For example, MediaNet allows a concept such as car to be defined as a type of a transportation vehicle, but which is further defined and illustrated through example images, videos and sounds of cars. In constructing the MediaNet framework, we have built on the basic principles of semiotics and semantic networks in addition to utilizing the audio-visual content description framework being developed as part of the MPEG-7 multimedia content description standard. By integrating both conceptual and perceptual representations of knowledge, MediaNet has potential to impact a broad range of applications that deal with multimedia content at the semantic and perceptual levels. In particular, we have found that MediaNet can improve the performance of multimedia retrieval applications by using query expansion, refinement and translation across multiple content modalities. In this paper, we report on experiments that use MediaNet in searching for images. We construct the MediaNet knowledge base using both WordNet and an image network built from multiple example images and extracted color and texture descriptors. Initial experimental results demonstrate improved retrieval effectiveness using MediaNet in a content-based retrieval system.

Multimedia and children in Turkey.

PubMed

Tuncer, A M; Yalçin, S S

1999-01-01

Multimedia will be regarded as essential tools for children to create their new world. The effects of television on young children's life have been well studied. Television differs, however, from other media, including the movies, in its pervasive impact on children. Children spend more time watching television than any other activity except sleeping. Overall 31% of children spent at least 4 hours a day watching television during weekday and 71.7% during weekend in Turkey. Television's influence on children is a function of the length of time they spend watching and the cumulative effect of what they see. Television may be a cause as well as a solution for many serious childhood problems. Excessive viewing of television has also been linked to aggressive behavior, violence, childhood obesity. On the other hand, television may act as a socializing agent and as a learning tool if the recommendations of American Academy of Pediatrics is learned by pediatricians, parents and broadcasters. The use of home personal computers in urban residence increased from 3.2% in 1993 to 6.5% by January 1998 in Turkey. Around 20% of computer households reported owing a modem. Internet has been using only for 5 years in Turkey. Nearly 40% of computer households also used CD-ROM equipment. The percentage of schools that have a computer laboratory is only 2.64%. On the other hand, multimedia allows students to move away from a uniform education for everyone to assert individual identity, liberalize education and management. It seems likely that, within the next few years, most of the countries with substantial internet infrastructure will use the internet as the major medium for disseminating information, including information on children. To prepare students for such a world demands that educational systems make the best possible use of all knowledge and technologies currently available.

The use of multimedia as an adjunct to the informed consent process for Morton's neuroma resection surgery.

2014-10-01

The purpose of this study was to assess if a computer-based multimedia education module (MEM) improved patients' comprehension when used as an adjunct to the standard verbal consent process for Morton's neuroma resection surgery. Nineteen patients (15 females and 4 males) considered candidates for Morton's neuroma resection surgery were prospectively recruited. A standardized verbal discussion was had with each patient regarding risks and benefits of surgery, alternative treatments, and the usual postoperative course. Patient understanding was then assessed with a questionnaire. Each patient subsequently viewed the MEM and the questionnaire was repeated. Patients also rated ease of understanding and satisfaction with both methods of patient education. Patients answered a significantly greater proportion of correct answers after viewing the MEM module (85%), compared to verbal discussion alone (61%) (P = .002). Patients rated both the ease of understanding of the module and amount of information provided by the module as a mean of 9.3 cm on a 10 cm Visual Analog Scale (VAS). The majority of patients (76%) rated the multimedia tool as having answered their questions about surgery as well or better than the treating surgeon. An interactive multimedia educational tool was a useful adjunct to the informed consent process for patients considering Morton's neuroma resection surgery.

Tzelepi, S; Pangalos, G; Nikolacopoulou, G

2002-09-01

The application of information technology to health care has generated growing concern about the privacy and security of medical information. Furthermore, data and communication security requirements in the field of multimedia are higher. In this paper we describe firstly the most important security requirements that must be fulfilled by multimedia medical data, and the security measures used to satisfy these requirements. These security measures are based mainly on modern cryptographic and watermarking mechanisms as well as on security infrastructures. The objective of our work is to complete this picture, exploiting the capabilities of multimedia medical data to define and implement an authorization model for regulating access to the data. In this paper we describe an extended role-based access control model by considering, within the specification of the role-permission relationship phase, the constraints that must be satisfied in order for the holders of the permission to use those permissions. The use of constraints allows role-based access control to be tailored to specifiy very fine-grained and flexible content-, context- and time-based access control policies. Other restrictions, such as role entry restriction also can be captured. Finally, the description of system architecture for a secure DBMS is presented.

WikiHyperGlossary (WHG): an information literacy technology for chemistry documents.

PubMed

Bauer, Michael A; Berleant, Daniel; Cornell, Andrew P; Belford, Robert E

2015-01-01

The WikiHyperGlossary is an information literacy technology that was created to enhance reading comprehension of documents by connecting them to socially generated multimedia definitions as well as semantically relevant data. The WikiHyperGlossary enhances reading comprehension by using the lexicon of a discipline to generate dynamic links in a document to external resources that can provide implicit information the document did not explicitly provide. Currently, the most common method to acquire additional information when reading a document is to access a search engine and browse the web. This may lead to skimming of multiple documents with the novice actually never returning to the original document of interest. The WikiHyperGlossary automatically brings information to the user within the current document they are reading, enhancing the potential for deeper document understanding. The WikiHyperGlossary allows users to submit a web URL or text to be processed against a chosen lexicon, returning the document with tagged terms. The selection of a tagged term results in the appearance of the WikiHyperGlossary Portlet containing a definition, and depending on the type of word, tabs to additional information and resources. Current types of content include multimedia enhanced definitions, ChemSpider query results, 3D molecular structures, and 2D editable structures connected to ChemSpider queries. Existing glossaries can be bulk uploaded, locked for editing and associated with multiple social generated definitions. The WikiHyperGlossary leverages both social and semantic web technologies to bring relevant information to a document. This can not only aid reading comprehension, but increases the users' ability to obtain additional information within the document. We have demonstrated a molecular editor enabled knowledge framework that can result in a semantic web inductive reasoning process, and integration of the WikiHyperGlossary into other software technologies, like the Jikitou Biomedical Question and Answer system. Although this work was developed in the chemical sciences and took advantage of open science resources and initiatives, the technology is extensible to other knowledge domains. Through the DeepLit (Deeper Literacy: Connecting Documents to Data and Discourse) startup, we seek to extend WikiHyperGlossary technologies to other knowledge domains, and integrate them into other knowledge acquisition workflows.

Use of Multimedia Technology in the Doctor-Patient Relationship for Obtaining Patient Informed Consent.

PubMed

Michalski, Andrzej; Stopa, Marcin; Miśkowiak, Bogdan

2016-10-26

Patient informed consent for surgery or for high-risk methods of treatment or diagnosis means that unlawful breach of the patient's personal interests is avoided and the patient accepts the risk of surgery and takes the brunt of it. Patient awareness - their knowledge of the condition and circumstances of continued therapeutic procedure, including offered and available methods of treatment and their possible complications - constitutes a particular aspect of the informed-consent process. The rapid development of technologies and methods of treatment may cause communication problems between the doctor and the patient regarding the scope and method of patient education prior to surgery. The use of multimedia technology (e.g., videos of surgical procedures, computer animation, and graphics), in addition to media used in preoperative patient education, may be a factor in improving the quality of the informed consent process. Studies conducted in clinical centers show that with use of multimedia technology, patients remember more of the information presented. The use of new technology also makes it possible to reduce the difference in the amount of information assimilated by patients with different levels of education. The use of media is a way to improve the quality of preoperative patient education and, at the same time, a step towards their further empowerment in the healing process.

An Ambient Intelligence Framework for the Provision of Geographically Distributed Multimedia Content to Mobility Impaired Users

Kehagias, Dionysios D.; Giakoumis, Dimitris; Tzovaras, Dimitrios; Bekiaris, Evangelos; Wiethoff, Marion

This chapter presents an ambient intelligence framework whose goal is to facilitate the information needs of mobility impaired users on the move. This framework couples users with geographically distributed services and the corresponding multimedia content, enabling access to context-sensitive information based on user geographic location and the use case under consideration. It provides a multi-modal facility that is realized through a set of mobile devices and user interfaces that address the needs of ten different types of user impairments. The overall ambient intelligence framework enables users who are equipped with mobile devices to access multimedia content in order to undertake activities relevant to one or more of the following domains: transportation, tourism and leisure, personal support services, work, business, education, social relations and community building. User experience is being explored against those activities through a specific usage scenario.

Sociospace: A smart social framework based on the IP Multimedia Subsystem

NASA Astrophysics Data System (ADS)

Hasswa, Ahmed

Advances in smart technologies, wireless networking, and increased interest in contextual services have led to the emergence of ubiquitous and pervasive computing as one of the most promising areas of computing in recent years. Smart Spaces, in particular, have gained significant interest within the research community. Currently, most Smart Spaces rely on physical components, such as sensors, to acquire information about the real-world environment. Although current sensor networks can acquire some useful contextual information from the physical environment, their information resources are often limited, and the data acquired is often unreliable. We argue that by introducing social network information into such systems, smarter and more adaptive spaces can be created. Social networks have recently become extremely popular, and are now an integral part of millions of people's daily lives. Through social networks, users create profiles, build relationships, and join groups, forming intermingled sets and communities. Social Networks contain a wealth of information, which, if exploited properly, can lead to a whole new level of smart contextual services. A mechanism is therefore needed to extract data from heterogeneous social networks, to link profiles across different networks, and to aggregate the data obtained. We therefore propose the design and implementation of a Smart Spaces framework that utilizes the social context. In order to manage services and sessions, we integrate our system with the IP Multimedia Subsystem. Our system, which we call SocioSpace, includes full design and implementation of all components, including the central server, the location management system, the social network interfacing system, the service delivery platform, and user agents. We have built a prototype for proof of concept and carried out exhaustive performance analysis; the results show that SocioSpace is scalable, extensible, and fault-tolerant. It is capable of creating Smart Spaces that can truly deliver adaptive services that enhance the users' overall experience, increase their satisfaction, and make the surroundings more beneficial and interesting to them.

Video database research is commonly concerned with the storage and retrieval of visual information invovling sequence segmentation, shot representation and video clip retrieval. In multimedia applications, video sequences are usually accompanied by a sound track. The sound track contains potential cues to aid shot segmentation such as different speakers, background music, singing and distinctive sounds. These different acoustic categories can be modeled to allow for an effective database retrieval. In this paper, we address the problem of automatic segmentation of audio track of multimedia material. This audio based segmentation can be combined with video scene shot detection in order to achieve partitioning of the multimedia material into semantically significant segments.

While most young people who smoke want to quit, few access cessation support services. Mobile phone-based cessation programs are ideal for young people: mobile phones are the most common means of peer communication, and messages can be delivered in an anonymous manner, anywhere, anytime. Following the success of our text messaging smoking cessation program, we developed an innovative multimedia mobile phone smoking cessation intervention. The aim of the study was to develop and pilot test a youth-oriented multimedia smoking cessation intervention delivered solely by mobile phone. Development included creating content and building the technology platform. Content development was overseen by an expert group who advised on youth development principles, observational learning (from social cognitive theory), effective smoking cessation interventions, and social marketing. Young people participated in three content development phases (consultation via focus groups and an online survey, content pre-testing, and selection of role models). Video and text messages were then developed, incorporating the findings from this research. Information technology systems were established to support the delivery of the multimedia messages by mobile phone. A pilot study using an abbreviated 4-week program of video and text content tested the reliability of the systems and the acceptability of the intervention. Approximately 180 young people participated in the consultation phase. There was a high priority placed on music for relaxation (75%) and an interest in interacting with others in the program (40% would read messages, 36% would read a blog). Findings from the pre-testing phase (n = 41) included the importance of selecting "real" and "honest" role models with believable stories, and an interest in animations (37%). Of the 15 participants who took part in the pilot study, 13 (87%) were available for follow-up interviews at 4 weeks: 12 participants liked the program or liked it most of the time and found the role model to be believable; 7 liked the role model video messages (5 were unsure); 8 used the extra assistance for cravings; and 9 were happy with two messages per day. Nine participants (60%) stopped smoking during the program. Some technical challenges were encountered during the pilot study. A multimedia mobile phone smoking cessation program is technically feasible, and the content developed is appropriate for this medium and is acceptable to our target population. These results have informed the design of a 6-month intervention currently being evaluated for its effectiveness in increasing smoking cessation rates in young people.

The anticipated increase in popular use of the Internet has created more opportunity in information dissemination, Ecommerce, and multimedia communication. It has also created more challenges in organizing information and facilitating its efficient retrieval. In response to this, new techniques have evolved which facilitate the creation of such applications. Certainly the most promising among the new paradigms is the use of mobile agents. In this paper, mobile agent and distributed database technologies are applied in the banking system. Many approaches have been proposed to schedule data items for broadcasting in a mobile environment. In this paper, an efficient strategy for accessing multiple data items in mobile environments and the bottleneck of current banking will be proposed.

That has motivated important standardization efforts, such as the IP Multimedia Subsystem (IMS) to support session control, mobility, and interoperability in all-IP next generation networks. Notwithstanding the central role of IMS in novel mobile multimedia, the potential of IMS-based service composition for the development of new classes of ready-to-use, energy-efficient, and cost-effective services is still widely unexplored. The paper proposes an original solution for the dynamic and standard-compliant redirection of incoming voice calls towards WiFi-equipped smart phones. The primary design guideline is to reduce energy consumption and service costs for the final user by automatically switching from the 3G to the WiFi infrastructure whenever possible. The proposal is fully compliant with the IMS standard and exploits the recently released IMS presence service to update device location and current communication opportunities. The reported experimental results point out that our solution, in a simple way and with full compliance with state-of-the-art industrially-accepted standards, can significantly increase battery lifetime without negative effects on call initiation delay.

Policy-Based Middleware for QoS Management and Signaling in the Evolved Packet System

NASA Astrophysics Data System (ADS)

Good, Richard; Gouveia, Fabricio; Magedanz, Thomas; Ventura, Neco

The 3GPP are currently finalizing their Evolved Packet System (EPS) with the Evolved Packet Core (EPC) central to this framework. The EPC is a simplified, flat, all IP-based architecture that supports mobility between heterogeneous access networks and incorporates an evolved QoS concept based on the 3GPP Policy Control and Charging (PCC) framework. The IP Multimedia Subsystem (IMS) is an IP service element within the EPS, introduced for the rapid provisioning of innovative multimedia services. The evolved PCC framework extends the scope of operation and defines new interactions - in particular the S9 reference point is introduced to facilitate inter-domain PCC communication. This paper proposes an enhancement to the IMS/PCC framework that uses SIP routing information to discover signaling and media paths. This mechanism uses standardized IMS/PCC operations and allows applications to effectively issue resource requests from their home domain enabling QoS-connectivity across multiple domains. Because the mechanism operates at the service control layer it does not require any significant transport layer modifications or the sharing of potentially sensitive internal topology information. The evolved PCC architecture and inter-domain route discovery mechanisms were implemented in an evaluation testbed and performed favorably without adversely effecting end user experience.

Patient centered healthcare delivery is an inherently collaborative process. This involves a wide range of individuals and organizations with diverse perspectives: primary care physicians, hospital administrators, labs, clinics, and insurance. The key to cost reduction and quality improvement in health care is effective management of this collaborative process. The use of multi-media collaboration technology can facilitate timely delivery of patient care and reduce cost at the same time. During the last five years, the Concurrent Engineering Research Center (CERC), under the sponsorship of DARPA (Defense Advanced Research Projects Agency, recently renamed ARPA) developed a number of generic key subsystems of a comprehensive collaboration environment. These subsystems are intended to overcome the barriers that inhibit the collaborative process. Three subsystems developed under this program include: MONET (Meeting On the Net)--to provide consultation over a computer network, ISS (Information Sharing Server)--to provide access to multi-media information, and PCB (Project Coordination Board)--to better coordinate focussed activities. These systems have been integrated into an open environment to enable collaborative processes. This environment is being used to create a wide-area (geographically distributed) research testbed under DARPA sponsorship, ARTEMIS (Advance Research Testbed for Medical Informatics) to explore the collaborative health care processes. We believe this technology will play a key role in the current national thrust to reengineer the present health-care delivery system.

Jones, Charles R.

Although a number of studies have been performed regarding the use of interactive multimedia disks in education, none were found which investigated their effect on either retention or recruitment for universities. The purpose of this case study was to gather information regarding student and teacher perceptions on the use of interactive multimedia disks and their effect on retention and recruitment. The primary source of data for this case study was student and teacher interviews. A purposive sample of students taking courses using the interactive multimedia disks in course at the Oregon Institute of Technology and at two Oregon high schools was chosen for the case study. Major findings of the case study were as follows: (1) Students interviewed in this case study perceived the interactive multimedia disk-based instructional method to be equally as effective as the lecture method. (2) Time flexibility in class scheduling was slightly more beneficial to female students than male students and the lack of instructor-led classroom interaction was more of a problem for female students than male students. (3) There was no difference in the perceptions of the college students and the high school students regarding the benefits and drawbacks of the interactive multimedia disk-based classes. (4) The flexible class scheduling made possible through the use of interactive multimedia disks influences some Oregon Institute of Technology students to stay and complete their degree programs. (5) There is some potential for interactive multimedia disk-based courses to be a recruiting tool. However, there is no evidence that it has been a successful recruiting tool for the Oregon Institute of Technology yet.

The current Internet success has already changed our social and economic world and is still continuing to revolutionize the information exchange. The exponential increase of amount and types of data that is currently exchanged on the Internet represents significant challenge for the design of future architectures and solutions. This paper reviews the current status and trends in the design of solutions and research activities in the future Internet from point of view of managing the growth of bandwidth requirements and complexity of the multimedia that is being created and shared. Outlines the challenges that are present before the video coding and approaches to the design of standardized media formats and protocols while considering the expected convergence of multimedia formats and exchange interfaces. The rapid growth of connected mobile devices adds to the current and the future challenges in combination with the expected, in near future, arrival of multitude of connected devices. The new Internet technologies connecting the Internet of Things with wireless visual sensor networks and 3D virtual worlds requires conceptually new approaches of media content handling from acquisition to presentation in the 3D Media Internet. Accounting for the entire transmission system properties and enabling adaptation in real-time to context and content throughout the media proceeding path will be paramount in enabling the new media architectures as well as the new applications and services. The common video coding formats will need to be conceptually redesigned to allow for the implementation of the necessary 3D Media Internet features.

Use of Multimedia Technology in the Doctor-Patient Relationship for Obtaining Patient Informed Consent

Michalski, Andrzej; Stopa, Marcin; Miśkowiak, Bogdan

2016-01-01

Patient informed consent for surgery or for high-risk methods of treatment or diagnosis means that unlawful breach of the patient’s personal interests is avoided and the patient accepts the risk of surgery and takes the brunt of it. Patient awareness – their knowledge of the condition and circumstances of continued therapeutic procedure, including offered and available methods of treatment and their possible complications – constitutes a particular aspect of the informed-consent process. The rapid development of technologies and methods of treatment may cause communication problems between the doctor and the patient regarding the scope and method of patient education prior to surgery. The use of multimedia technology (e.g., videos of surgical procedures, computer animation, and graphics), in addition to media used in preoperative patient education, may be a factor in improving the quality of the informed consent process. Studies conducted in clinical centers show that with use of multimedia technology, patients remember more of the information presented. The use of new technology also makes it possible to reduce the difference in the amount of information assimilated by patients with different levels of education. The use of media is a way to improve the quality of preoperative patient education and, at the same time, a step towards their further empowerment in the healing process. PMID:27780964

Despite mounting interest in entrepreneurship education (EE), innovative approaches such as multimedia, web-based toolkits including entrepreneurial storytelling have been largely ignored in the EE discipline. Therefore, this conceptual contribution introduces eight propositions as a fruitful basis for assessing a 'learning-through-real-multimedia-entrepreneurial-narratives' pedagogical approach. These recommendations prepare the grounds for a future, empirical investigation of this currently under-researched topic, which could be essential for multiple domains including academic, business and society.

An important part of NASA's mission involves the secondary application of its technologies in the public and private sectors. One current application under development is LiteraCity, a simulation-based instructional package for adults who do not have functional reading skills. Using fuzzy logic routines and other technologies developed by NASA's Information Systems Directorate and hypermedia sound, graphics, and animation technologies the project attempts to overcome the limited impact of adult literacy assessment and instruction by involving the adult in an interactive simulation of real-life literacy activities. The project uses a recursive instructional development model and authentic instruction theory. This paper describes one component of a project to design, develop, and produce a series of computer-based, multimedia instructional packages. The packages are being developed for use in adult literacy programs, particularly in correctional education centers. They use the concepts of authentic instruction and authentic assessment to guide development. All the packages to be developed are instructional simulations. The first is a simulation of 'finding a friend a job.'

Comparative and Predictive Multimedia Assessments Using Monte Carlo Uncertainty Analyses

Whelan, G.

2002-05-01

Multiple-pathway frameworks (sometimes referred to as multimedia models) provide a platform for combining medium-specific environmental models and databases, such that they can be utilized in a more holistic assessment of contaminant fate and transport in the environment. These frameworks provide a relatively seamless transfer of information from one model to the next and from databases to models. Within these frameworks, multiple models are linked, resulting in models that consume information from upstream models and produce information to be consumed by downstream models. The Framework for Risk Analysis in Multimedia Environmental Systems (FRAMES) is an example, which allows users to link their models to other models and databases. FRAMES is an icon-driven, site-layout platform that is an open-architecture, object-oriented system that interacts with environmental databases; helps the user construct a Conceptual Site Model that is real-world based; allows the user to choose the most appropriate models to solve simulation requirements; solves the standard risk paradigm of release transport and fate; and exposure/risk assessments to people and ecology; and presents graphical packages for analyzing results. FRAMES is specifically designed allow users to link their own models into a system, which contains models developed by others. This paper will present the use of FRAMES to evaluate potential human health exposures using real site data and realistic assumptions from sources, through the vadose and saturated zones, to exposure and risk assessment at three real-world sites, using the Multimedia Environmental Pollutant Assessment System (MEPAS), which is a multimedia model contained within FRAMES. These real-world examples use predictive and comparative approaches coupled with a Monte Carlo analysis. A predictive analysis is where models are calibrated to monitored site data, prior to the assessment, and a comparative analysis is where models are not calibrated but based solely on literature or judgement and is usually used to compare alternatives. In many cases, a combination is employed where the model is calibrated to a portion of the data (e.g., to determine hydrodynamics), then used to compare alternatives. Three subsurface-based multimedia examples are presented, increasing in complexity. The first presents the application of a predictive, deterministic assessment; the second presents a predictive and comparative, Monte Carlo analysis; and the third presents a comparative, multi-dimensional Monte Carlo analysis. Endpoints are typically presented in terms of concentration, hazard, risk, and dose, and because the vadose zone model typically represents a connection between a source and the aquifer, it does not generally represent the final medium in a multimedia risk assessment.

This usability study evaluated users’ perceptions of a multimedia prototype for a new e-learning tool: Anatomy of the Central Nervous System: A Multimedia Course. Usability testing is a collection of formative evaluation methods that inform the developmental design of e-learning tools to maximize user acceptance, satisfaction, and adoption. Sixty-two study participants piloted the prototype and completed a usability questionnaire designed to measure two usability properties: program need and program applicability. Statistical analyses were used to test the hypothesis that the multimedia prototype was well designed and highly usable, it was perceived as: 1) highly needed across a spectrum of educational contexts, 2) highly applicable in supporting the pedagogical processes of teaching and learning neuroanatomy, and 3) was highly usable by all types of users. Three independent variables represented user differences: level of expertise (faculty vs. student), age, and gender. Analysis of the results supports the research hypotheses that the prototype was designed well for different types of users in various educational contexts and for supporting the pedagogy of neuroanatomy. In addition, the results suggest that the multimedia program will be most useful as a neuroanatomy review tool for health-professions students preparing for licensing or board exams. This study demonstrates the importance of integrating quality properties of usability with principles of human learning during the instructional design process for multimedia products. PMID:19177405

While in the area of relational databases interoperability is ensured by common communication protocols (e.g. ODBC/JDBC using SQL), Content Based Image Retrieval Systems (CBIRS) and other multimedia retrieval systems are lacking both a common query language and a common communication protocol. Besides its obvious short term convenience, interoperability of systems is crucial for the exchange and analysis of user data. In this paper, we present and describe an extensible XML-based query markup language, called MRML (Multimedia Retrieval markup Language). MRML is primarily designed so as to ensure interoperability between different content-based multimedia retrieval systems. Further, MRML allows researchers to preserve their freedom in extending their system as needed. MRML encapsulates multimedia queries in a way that enable multimedia (MM) query languages, MM content descriptions, MM query engines, and MM user interfaces to grow independently from each other, reaching a maximum of interoperability while ensuring a maximum of freedom for the developer. For benefitting from this, only a few simple design principles have to be respected when extending MRML for one's fprivate needs. The design of extensions withing the MRML framework will be described in detail in the paper. MRML has been implemented and tested for the CBIRS Viper, using the user interface Snake Charmer.

Visual aspects of perception of multimedia messages on the web through the "eye tracker" method.

PubMed

Svilicić, Niksa

Since the dawn of civilisation visual communication played a role in everyday life. In the early times there were simply shaped drawings of animals, pictograms explaining hunting tactics or strategies of attacking the enemies. Through evolution visual expression becomes an important component of communication process on several levels, from the existential and economic level to the artistic level. However, there was always a question of the level of user reception of such visual information in the medium transmitting the information. Does physical positioning of information in the medium contribute to the efficiency of the message? Do the same rules of content positioning apply for traditional (offline) and online media (Internet)? Rapid development of information technology and Internet in almost all segments of contemporary life calls for defining the rules of designing and positioning multimedia online contents on web sites. Recent research indicates beyond doubt that the physical positioning of an online content on a web site significantly determines the quality of user's perception of such content. By employing the "Eye tracking" method it is possible to objectively analyse the level of user perception of a multimedia content on a web site. What is the first thing observed by the user after opening the web site and how does he/she visually search the online content? By which methods can this be investigated subjectively and objectively? How can the survey results be used to improve the creation of web sites and to optimise the positioning of relevant contents on the site? The answers to these questions will significantly improve the presentation of multimedia interactive contents on the Web.

A Survey on Multimedia-Based Cross-Layer Optimization in Visual Sensor Networks

PubMed Central

Costa, Daniel G.; Guedes, Luiz Affonso

2011-01-01

Visual sensor networks (VSNs) comprised of battery-operated electronic devices endowed with low-resolution cameras have expanded the applicability of a series of monitoring applications. Those types of sensors are interconnected by ad hoc error-prone wireless links, imposing stringent restrictions on available bandwidth, end-to-end delay and packet error rates. In such context, multimedia coding is required for data compression and error-resilience, also ensuring energy preservation over the path(s) toward the sink and improving the end-to-end perceptual quality of the received media. Cross-layer optimization may enhance the expected efficiency of VSNs applications, disrupting the conventional information flow of the protocol layers. When the inner characteristics of the multimedia coding techniques are exploited by cross-layer protocols and architectures, higher efficiency may be obtained in visual sensor networks. This paper surveys recent research on multimedia-based cross-layer optimization, presenting the proposed strategies and mechanisms for transmission rate adjustment, congestion control, multipath selection, energy preservation and error recovery. We note that many multimedia-based cross-layer optimization solutions have been proposed in recent years, each one bringing a wealth of contributions to visual sensor networks. PMID:22163908

Semiotics and agents for integrating and navigating through multimedia representations of concepts

NASA Astrophysics Data System (ADS)

Joyce, Dan W.; Lewis, Paul H.; Tansley, Robert H.; Dobie, Mark R.; Hall, Wendy

1999-12-01

The purpose of this paper is two-fold. We begin by exploring the emerging trend to view multimedia information in terms of low-level and high-level components; the former being feature-based and the latter the 'semantics' intrinsic to what is portrayed by the media object. Traditionally, this has been viewed by employing analogies with generative linguistics. Recently, a new perceptive based on the semiotic tradition has been alluded to in several papers. We believe this to be a more appropriate approach. From this, we propose an approach for tackling this problem which uses an associative data structure expressing authored information together with intelligent agents acting autonomously over this structure. We then show how neural networks can be used to implement such agents. The agents act as 'vehicles' for bridging the gap between multimedia semantics and concrete expressions of high-level knowledge, but we suggest that traditional neural network techniques for classification are not architecturally adequate.

It is important to improve the efficiency of healthcare-related operations and the associated costs. Healthcare organizations are constantly under increased pressure to streamline operations and provide enhanced services to their patients. Wireless mobile computing technology has the potential to provide the desired benefits and would be a critical part of today's healthcare information system. In this paper, a system is presented to better facilitate the functions of physicians and medical staff in healthcare by using modern wireless mobile technology, Radio Frequency Identification (RFID) tools, and multimedia streaming. The paper includes a case study of the development of such a system in the context of healthcare in the United States. The results of the study show how wireless mobile multimedia systems can be developed for the improvement of the quality and efficiency in healthcare for other nations as well. Our testing data show a time reduction of more than 50% in the daily activities of hospital staff.

Social Media Visual Analytics for Events

For large-scale multimedia events such as televised debates and speeches, the amount of content on social media channels such as Facebook or Twitter can easily become overwhelming, yet still contain information that may aid and augment understanding of the multimedia content via individual social media items, or aggregate information from the crowd's response. In this work we discuss this opportunity in the context of a social media visual analytic tool, Vox Civitas, designed to help journalists, media professionals, or other researchers make sense of large-scale aggregations of social media content around multimedia broadcast events. We discuss the design of the tool, present and evaluate the text analysis techniques used to enable the presentation, and detail the visual and interaction design. We provide an exploratory evaluation based on a user study in which journalists interacted with the system to analyze and report on a dataset of over one 100 000 Twitter messages collected during the broadcast of the U.S. State of the Union presidential address in 2010.

Background Identifying disability early in life confers long-term benefits for children. The Taipei City Child Development Screening tool, second version (Taipei II) provides checklists for 13 child age groups from 4 months to 6 years. However, the usability of a text-based screening tool largely depends on the literacy level and logical reasoning ability of the caregivers, as well as language barriers caused by increasing numbers of immigrants. Objective The objectives of this study were to (1) design and develop a Web-based multimedia version of the current Taipei II developmental screening tool, and (2) investigate the measurement equivalence of this multimedia version to the original paper-based version. Methods To develop the multimedia version of Taipei II, a team of experts created illustrations, translations, and dubbing of the original checklists. The developmental screening test was administered to a total of 390 primary caregivers of children aged between 4 months and 6 years. Results Psychometric testing revealed excellent agreement between the paper and multimedia versions of Taipei II. Good to excellent reliabilities were demonstrated for all age groups for both the cross-mode similarity (mode intraclass correlation range 0.85-0.96) and the test-retest reliability (r=.93). Regarding the usability, the mean score was 4.80 (SD 0.03), indicating that users were satisfied with their multimedia website experience. Conclusions The multimedia tool produced essentially equivalent results to the paper-based tool. In addition, it had numerous advantages, such as it can facilitate active participation and promote early screening of target populations.

The effects of presentation pace and modality on learning a multimedia science lesson

NASA Astrophysics Data System (ADS)

Chung, Wen-Hung

Working memory is a system that consists of multiple components. The visuospatial sketchpad is the main entrance for visual and spatial information, whereas acoustic and verbal information is processed in the phonological loop. The central executive works as a coordinator of information from these two subsystems. Numerous studies have shown that working memory has a very limited capacity. Based on these characteristics of working memory, theories such as cognitive load theory and the cognitive theory of multimedia learning provide multimedia design principles. One of these principles is that when verbal information accompanying pictures is presented in audio mode instead of visually, learning can be more effective than if both text and pictures are presented visually. This is called the modality effect. However, some studies have found that the modality effect does not occur in some situations. In most experiments examining the modality effect, the multimedia is presented as system-paced. If learners are able to repeat listening as many times as they need, the superiority of spoken text over visual text seems lessened. One aim of this study was to examine the modality effect in a learner-controlled condition. This study also used the one-word-at-a-time technique to investigate whether the modality effect would still occur if both reading and listening rates were equal. There were 182 college students recruited for this study. Participants were randomly assigned to seven groups: a self-paced listening group, a self-paced reading group, a self text-block reading group, a general-paced listening group, a general-paced reading group, a fast-paced listening group, and a fast-paced reading group. The experimental material was a cardiovascular multimedia module. A three-by-two between-subjects design was used to test the main effect. Results showed that modality effect was still present but not between the self-paced listening group and the self text-block reading group. A post-study survey showed participants' different responses to the two modalities and their preferences as well. Results and research limitations are discussed and applications and future directions are also addressed.

Provision of preoperative information can alleviate patients' anxiety. However, the ideal method of delivering this information is unknown. Video information has been shown to reduce patients' anxiety, although little is known regarding the effect of preoperative multimedia information on anxiety in patients undergoing regional anaesthesia. We randomized 110 patients undergoing upper or lower limb surgery under regional anaesthesia into the study and control groups. The study group watched a short film (created by the authors) depicting the patient's in-hospital journey including either a spinal anaesthetic or a brachial plexus block. Patients' anxiety was assessed before and after the film and 1 h before and within 8 h after their operation, using the Spielberger state trait anxiety inventory and a visual analogue scale. There was no difference in state and trait anxiety between the two groups at enrollment. Women had higher baseline state and trait anxiety than men (P=0.02). Patients in the control group experienced an increase in state anxiety immediately before surgery (P<0.001), and patients in the film group were less anxious before operation than those in the control group (P=0.04). After operation, there was a decrease in state anxiety from baseline in both groups, but patients in the film group were less anxious than the control group (P=0.005). Preoperative multimedia information reduces the anxiety of patients undergoing surgery under regional anaesthesia. This type of information is easily delivered and can benefit many patients.

Comparative assessment of two interfaces for delivering a multimedia medical course in the French-speaking Virtual Medical University (UMVF).

The UMVF aims at helping medical students during their normal curriculum via the facilities provided by Internet based techniques. This paper describes a comparative assessment of two interfaces delivering a multimedia course: a conventional web server (WS) and an integrated e-learning platform in the form of a Virtual Campus (VC). Eleven students were arbitrarily divided into two groups. We used a qualitative method for comparing their acceptance of the on line course provided by the two different interfaces. The two groups were globally satisfied. However, a decrease in satisfaction was noted at the end of the experimentation in the VC group. This may be explained by a more complex Graphical User Interface (GUI) of the VC and some constraints which do not exist with the WS. The current e-learning platforms are probably not optimised for working conditions where presential and virtual activities are mixed. We think that a new type of "light" platforms should be developed for these specific working conditions. Students of the two groups also had limitations about the multimedia environment. They may change their opinion if they get more accustomed with the multimedia environment and if their teachers make a more adequate use of the multimedia techniques.

The emerging all-IP mobile network infrastructures based on 3rd Generation IP Multimedia Subsystem philosophy are characterised by radio access technology independence and ubiquitous connectivity for mobile users. Currently, great focus is being devoted to security issues since most of the security threats presently affecting the public Internet domain, and the upcoming ones as well, are going to be suffered by mobile users in the years to come. While a great deal of research activity, together with standardisation efforts and experimentations, is carried out on mechanisms for signalling protection, very few integrated frameworks for real-time multimedia data protection have been proposed in a context of IP Multimedia Subsystem, and even fewer experimental results based on testbeds are available. In this paper, after a general overview of the security issues arising in an advanced IP Multimedia Subsystem scenario, a comprehensive infrastructure for real-time multimedia data protection, based on the adoption of the Secure Real-Time Protocol, is proposed; then, the development of a testbed incorporating such functionalities, including mechanisms for key management and cryptographic context transfer, and allowing the setup of Secure Real-Time Protocol sessions is presented; finally, experimental results are provided together with quantitative assessments and comparisons of system performances for audio sessions with and without the adoption of the Secure Real-Time Protocol framework.

Surgery is a highly stressful event for children and caregivers. Extensive effort has been made to improve preoperative care in order to alleviate worry about the surgical procedure itself. This study tested the impact of an educational multimedia intervention on the cognitive, emotional, and physiological responses of children undergoing surgery, as well as on parental state anxiety. Children (n = 90) were assigned to three different groups: an educational multimedia intervention (experimental group), an entertainment video game intervention (comparison group), and a control group (no intervention). Children who received the educational multimedia intervention reported lower level of worries about hospitalization, medical procedures, illness, and negative consequences than those in the control and in the comparison groups. Parental state anxiety was also lower in the both the educational and the entertainment video game interventions compared to the control group. These findings suggest that providing information to children regarding medical procedures and hospital rules and routines is important to reduce their preoperative worries, and also relevant for parental anxiety.

Despite mounting interest in entrepreneurship education (EE), innovative approaches such as multimedia, web-based toolkits including entrepreneurial storytelling have been largely ignored in the EE discipline. Therefore, this conceptual contribution introduces eight propositions as a fruitful basis for assessing a ‘learning-through-real-multimedia-entrepreneurial-narratives’ pedagogical approach. These recommendations prepare the grounds for a future, empirical investigation of this currently under-researched topic, which could be essential for multiple domains including academic, business and society.

Despite the high costs involved and the lack of definitive evidence of sustained effectiveness, many low- and middle-income countries had begun to strengthen their health information system using information and communication technology in the past few decades. Following this international trend, the Malaysian Ministry of Health had been incorporating Telehealth (National Telehealth initiatives) into national health policies since the 1990s. Employing qualitative approaches, including key informant interviews and document review, this study examines the agenda-setting processes of the Telehealth policy using Kingdon's framework. The findings suggested that Telehealth policies emerged through actions of policy entrepreneurs within the Ministry of Health, who took advantage of several simultaneously occurring opportunities--official recognition of problems within the existing health information system, availability of information and communication technology to strengthen health information system and political interests surrounding the national Multimedia Super Corridor initiative being developed at the time. The last was achieved by the inclusion of Telehealth as a component of the Multimedia Super Corridor. © 2015 APJPH.

Although web-based, multimedia smoking prevention programs have been tested in several high-income countries, their efficacy in Central and Eastern Europe is unknown. The aim of this trial was to assess the short-term effects of ASPIRA, among Romanian and Hungarian speaking ninth graders in Tirgu Mures, Romania. ASPIRA is the Romanian acronym for the translated and adapted version of ASPIRE, "A Smoking Prevention Interactive Experience," an evidence-based smoking prevention program originally developed to prevent tobacco use among high school students in the United States. Sixteen high schools in Tirgu Mures, Romania were randomized to receive five weekly sessions of the ASPIRA web-based, multimedia program or to a control condition. Socio-demographic data, psychosocial characteristics, and smoking behavior were collected from students at baseline and at 6 months. A hierarchical logistic regression analysis was conducted to test the efficacy of the intervention on smoking initiation and current smoking among 1369 students. Never-smoker students in the intervention arm were 35% less likely to report smoking initiation 6 months after the baseline assessment (OR = 0.65, 95%CI: 0.44-0.97). Reduced smoking initiation was observed most notably among students who were exposed to at least 75% of the ASPIRA program. There was no statistically significant effect of the intervention on current tobacco use (OR = 0.80, 95%CI: 0.44-1.46). ASPIRA, an adapted version of the evidence-based, multimedia ASPIRE program that was originally developed and tested in the United States may decrease smoking initiation among multi-ethnic adolescents in Central and Eastern Europe. (1). Web-based, multimedia smoking prevention programs may be effective tools to prevent smoking initiation among multi-ethnic adolescent communities in Central and Eastern Europe. (2). The degree of exposure is critical, only high exposure to the multimedia smoking prevention program is associated with reduced smoking initiation. © The Author 2016.

Multi-agent Negotiation Mechanisms for Statistical Target Classification in Wireless Multimedia Sensor Networks

Wang, Xue; Bi, Dao-wei; Ding, Liang; Wang, Sheng

2007-01-01

The recent availability of low cost and miniaturized hardware has allowed wireless sensor networks (WSNs) to retrieve audio and video data in real world applications, which has fostered the development of wireless multimedia sensor networks (WMSNs). Resource constraints and challenging multimedia data volume make development of efficient algorithms to perform in-network processing of multimedia contents imperative. This paper proposes solving problems in the domain of WMSNs from the perspective of multi-agent systems. The multi-agent framework enables flexible network configuration and efficient collaborative in-network processing. The focus is placed on target classification in WMSNs where audio information is retrieved by microphones. To deal with the uncertainties related to audio information retrieval, the statistical approaches of power spectral density estimates, principal component analysis and Gaussian process classification are employed. A multi-agent negotiation mechanism is specially developed to efficiently utilize limited resources and simultaneously enhance classification accuracy and reliability. The negotiation is composed of two phases, where an auction based approach is first exploited to allocate the classification task among the agents and then individual agent decisions are combined by the committee decision mechanism. Simulation experiments with real world data are conducted and the results show that the proposed statistical approaches and negotiation mechanism not only reduce memory and computation requirements in WMSNs but also significantly enhance classification accuracy and reliability.

Data show that many research subjects have difficulty understanding study information using traditional paper consent documents. This study, therefore, was designed to evaluate the effect of an interactive multimedia program on improving parents' and children's understanding of clinical trial concepts and participation. Parents (n=148) and children (n=135) were each randomised to receive information regarding clinical trials using either a traditional paper format (TF) or an interactive iPad program (IP) with inline exercises. Participants' understanding of the information was assessed using semistructured interviews prior to (pretest) and after (post-test) receiving the information. Participants also completed a short survey to assess their perceptions of information delivery and satisfaction with the process. Regardless of the mode of information delivery, all participants demonstrated improved pretest to post-test understanding. While there were no statistical differences in parents' post-test understanding between the TF and IP groups, children in the IP group had significantly greater post-test understanding compared with children in the TF group (11.65 (4.1) vs 8.85 (4.1) (2.8, 1.4, 4.2) 0-18 scale where 18=complete understanding). Furthermore, the IP was found to be significantly 'easier to follow' and 'more effective' in presenting information compared with the TF. Results demonstrated the importance of providing information regarding clinical trial concepts to parents and children. Importantly, the ability of interactive multimedia to improve understanding of clinical trial concepts and satisfaction with information delivery, particularly among children, supports this approach as a novel and effective vehicle for enhancing the informed consent process.

Spencer, Sandra P; Stoner, Michael J; Kelleher, Kelly; Cohen, Daniel M

2015-08-01

Informed consent is an ethical process for ensuring patient autonomy. Multimedia presentations (MMPs) often aid the informed consent process for research studies. Thus, it follows that MMPs would improve informed consent in clinical settings. The aim of this study was to determine if an MMP for the informed consent process for ketamine sedation improves parental satisfaction and comprehension as compared with standard practice. This 2-phase study compared 2 methods of informed consent for ketamine sedation of pediatric patients. Phase 1 was a randomized, prospective study that compared the standard verbal consent to an MMP. Phase 2 implemented the MMP into daily work flow to validate the previous year's results. Parents completed a survey evaluating their satisfaction of the informed consent process and assessing their knowledge of ketamine sedation. Primary outcome measures were parental overall satisfaction with the informed consent process and knowledge of ketamine sedation. One hundred eighty-four families from a free-standing, urban, tertiary pediatric emergency department with over 85,000 annual visits were enrolled. Different demographics were not associated with a preference for the MMP or improved scores on the content quiz. Intervention families were more likely "to feel involved in the decision to use ketamine" and to understand that "they had the right to refuse the ketamine" as compared with control families. The intervention group scored significantly higher overall on the content section than the control group. Implementation and intervention families responded similarly to all survey sections. Multimedia presentation improves parental understanding of ketamine sedation, whereas parental satisfaction with the informed consent process remains unchanged. Use of MMP in the emergency department for informed consent shows potential for both patients and providers.

Patient centered healthcare delivery is an inherently collaborative process. This involves a wide range of individuals and organizations with diverse perspectives: primary care physicians, hospital administrators, labs, clinics, and insurance. The key to cost reduction and quality improvement in health care is effective management of this collaborative process. The use of multi-media collaboration technology can facilitate timely delivery of patient care and reduce cost at the same time. During the last five years, the Concurrent Engineering Research Center (CERC), under the sponsorship of DARPA (Defense Advanced Research Projects Agency, recently renamed ARPA) developed a number of generic key subsystems of a comprehensive collaboration environment. These subsystems are intended to overcome the barriers that inhibit the collaborative process. Three subsystems developed under this program include: MONET (Meeting On the Net)--to provide consultation over a computer network, ISS (Information Sharing Server)--to provide access to multi-media information, and PCB (Project Coordination Board)--to better coordinate focussed activities. These systems have been integrated into an open environment to enable collaborative processes. This environment is being used to create a wide-area (geographically distributed) research testbed under DARPA sponsorship, ARTEMIS (Advance Research Testbed for Medical Informatics) to explore the collaborative health care processes. We believe this technology will play a key role in the current national thrust to reengineer the present health-care delivery system. PMID:8130536

Background/aims Participant understanding is a key element of informed consent for enrollment in research. However, participants often do not understand the nature, risks, benefits, or design of the studies in which they take part. Research on medical practices, which studies standard interventions rather than new treatments, has the potential to be especially confusing to participants because it is embedded within usual clinical care. Our objective in this randomized study was to compare the ability of a range of multimedia informational aids to improve participant understanding in the context of research on medical practices. Methods We administered a Web-based survey to members of a proprietary online panel sample selected to match national U.S. demographics. Respondents were randomized to one of five arms: four content-equivalent informational aids (animated videos, slideshows with voiceover, comics, and text), and one no-intervention control. We measured knowledge of research on medical practices using a summary knowledge score from 10 questions based on the content of the informational aids. We used ANOVA and paired t-tests to compare knowledge scores between arms. Results There were 1500 completed surveys (300 in each arm). Mean knowledge scores were highest for the slideshows with voiceover (65.7%), followed by the animated videos (62.7%), comics (60.7%), text (57.2%), and control (50.3%). Differences between arms were statistically significant except between the slideshows with voiceover and animated videos and between the animated videos and comics. Informational aids that included an audio component (animated videos and slideshows with voiceover) had higher knowledge scores than those without an audio component (64.2% versus 59.0%, p<.0001). There was no difference between informational aids with a character-driven story component (animated videos and comics) and those without. Conclusions Our results show that simple multimedia aids that use a dual-channel approach, such as voiceover with visual reinforcement, can improve participant knowledge more effectively than text alone. However, the relatively low knowledge scores suggest that targeted informational aids may be needed to teach some particularly challenging concepts. Nonetheless, our results demonstrate the potential to improve informed consent for research on medical practices by using multimedia aids that include simplified language and visual metaphors.

Many anesthesia departments operate a pre-anesthesia assessment clinic (PAAC). Data regarding organization, equipment and structure of such clinics are not yet available. Information about modern anesthesiology techniques and procedures contributes to a reduction in emotional stress of the patients but such modern techniques often require additional technical hardware and costs and are not equally available. This survey examined the current structures of PAAC in the state of Hessen, demonstrated current concepts and associated these with the performance and the portfolio of procedures in these departments. An online survey was carried out. Data on structure, equipment, organization and available methods were compiled. In addition, anesthesia department personnel were asked to give individual subjective attitudes toward the premedication work. Of the anesthesia departments in Hessen 84 % participated in the survey of which 91 % operated a PAAC. A preoperative contact with the anesthesiologist who would perform anesthesia existed in only 19 % of the departments. Multimedia processing concepts for informed consent in a PAAC setting were in general rare. Many modern procedures and anesthesia techniques were broadly established independent of the hospital size. Regarding the individual and subjective attitudes of anesthetists towards the work, the psychological and medical importance of the pre-medication visit was considered to be very high. The PAACs are now well established. This may make economic sense but is accompanied by an anonymization of care in anesthesiology. The high quality, safety and availability of modern anesthesiology procedures and monitoring concepts should be communicated to patients all the more as an expression of trust and high patient safety. These factors can be facilitated in particular by multimedia tools which have as yet only been sparsely implemented in PAACs.

Exploring creative activity: a software environment for multimedia systems

1992-03-01

This paper examines various issues related to the theory, design, and implementation of a system that supports creative activity for a multimedia environment. The system incorporates artificial intelligence notions to acquire concepts of the problem domain. This paper investigates this environment by considering a model that is a basis for a system, which supports a history of user interaction. A multimedia system that supports creative activity is problematic. It must function as a tool allowing users to experiment dynamically with their own creative reasoning process--a very nebulous task environment. It should also support the acquisition of domain knowledge so that empirical observation can be further evaluated. This paper aims to illustrate that via the reuse of domain-specific knowledge, closely related ideas can be quickly developed. This approach is useful in the following sense: Multimedia navigational systems hardcode referential links with respect to a web or network. Although users can access or control navigation in a nonlinear (static) manner, these referential links are 'frozen' and can not capture their creative actions, which are essential in tutoring or learning applications. This paper describes a multimedia assistant based on the notion of knowledge- links, which allows users to navigate through creative information in a nonlinear (dynamic) fashion. A selection of prototype code based on object-oriented techniques and logic programming partially demonstrates this.

A secure cluster-based multipath routing protocol for WMSNs.

2011-01-01

The new characteristics of Wireless Multimedia Sensor Network (WMSN) and its design issues brought by handling different traffic classes of multimedia content (video streams, audio, and still images) as well as scalar data over the network, make the proposed routing protocols for typical WSNs not directly applicable for WMSNs. Handling real-time multimedia data requires both energy efficiency and QoS assurance in order to ensure efficient utility of different capabilities of sensor resources and correct delivery of collected information. In this paper, we propose a Secure Cluster-based Multipath Routing protocol for WMSNs, SCMR, to satisfy the requirements of delivering different data types and support high data rate multimedia traffic. SCMR exploits the hierarchical structure of powerful cluster heads and the optimized multiple paths to support timeliness and reliable high data rate multimedia communication with minimum energy dissipation. Also, we present a light-weight distributed security mechanism of key management in order to secure the communication between sensor nodes and protect the network against different types of attacks. Performance evaluation from simulation results demonstrates a significant performance improvement comparing with existing protocols (which do not even provide any kind of security feature) in terms of average end-to-end delay, network throughput, packet delivery ratio, and energy consumption.

In this paper we provide a foundation for a new generation of services and tools. We define new ways of capturing, sharing and reusing information and intelligence provided by single users and communities, as well as organizations by enabling the extraction, generation, interpretation and management of Collective Intelligence from user generated digital multimedia content. Different layers of intelligence are generated, which together constitute the notion of Collective Intelligence. The automatic generation of Collective Intelligence constitutes a departure from traditional methods for information sharing, since information from both the multimedia content and social aspects will be merged, while at the same time the social dynamics will be taken into account. In the context of this work, we present two case studies: an Emergency Response and a Consumers Social Group case study.

With the technology development of network information, there exists more and more seriously questions to our education. Computer multimedia application breaks the traditional foreign language teaching and brings new challenges and opportunities for the education. Through the multiple media application, the teaching process is full of animation, image, voice, and characters. This can improve the learning initiative and objective with great development of learning efficiency. During the traditional foreign language teaching, people use characters learning. However, through this method, the theory performance is good but the practical application is low. During the long time computer multimedia application in the foreign language teaching, many teachers still have prejudice. Therefore, the method is not obtaining the effect. After all the above, the research has significant meaning for improving the teaching quality of foreign language.

A computer-based training system combining virtual reality and multimedia

Training new users of complex machines is often an expensive and time-consuming process. This is particularly true for special purpose systems, such as those frequently encountered in DOE applications. This paper presents a computer-based training system intended as a partial solution to this problem. The system extends the basic virtual reality (VR) training paradigm by adding a multimedia component which may be accessed during interaction with the virtual environment. The 3D model used to create the virtual reality is also used as the primary navigation tool through the associated multimedia. This method exploits the natural mapping between a virtual world and the real world that it represents to provide a more intuitive way for the student to interact with all forms of information about the system.

We present a dataset that combines multimodal biosignals and eye tracking information gathered under a human-computer interaction framework. The dataset was developed in the vein of the MAMEM project that aims to endow people with motor disabilities with the ability to edit and author multimedia content through mental commands and gaze activity. The dataset includes EEG, eye-tracking, and physiological (GSR and Heart rate) signals collected from 34 individuals (18 able-bodied and 16 motor-impaired). Data were collected during the interaction with specifically designed interface for web browsing and multimedia content manipulation and during imaginary movement tasks. The presented dataset will contribute towards the development and evaluation of modern human-computer interaction systems that would foster the integration of people with severe motor impairments back into society.

Many studies have shown that providing health education before surgery may significantly increase health knowledge and decrease anxiety in both patients and their family members. However, few studies have compared the effects on pediatric outpatient surgery outcomes of different health education instruction modes. This study compares the effects of two health education delivery modes on maternal knowledge and anxiety, the number of unexpected early hospital follow-up visits, and the time spent by nurses on health education. A quasi-experimental design with pretest and posttest was used to compare the effect on the outcomes of pediatric circumcision of a multimedia compact disc (CD) and a printed material.Seventy mothers of children who underwent Plastibell circumcision participated in this study. Both the printed material and the multimedia CD significantly increased the knowledge and reduced the anxiety levels of the participants. However, no significant differences in unscheduled early hospital follow-up visits postsurgery were found between the two modes of instruction. Furthermore, we found that significantly fewer hours were spent by nurses on health education for the multimedia CD group in comparison with the printed material group. In the current clinical environment of common staffing shortages, information tools may be used to cost-effectively assist and simplify nursing work. The findings of this study may provide a reference to medical centers that are working to reduce the time spent by nurses on health education for outpatient surgery patients. Furthermore, audiovisual health education tools are recommended to increase nursing effectiveness and save nursing time.

Safety production of coalmines is a task of top priority which plays an important role in guaranteeing, supporting and promoting the continuous development of the coal industry. Since traditional wireless sensor networks (WSNs) cannot fully meet the requirements of comprehensive environment monitoring of underground coalmines, wireless multimedia sensor networks (WMSNs), enabling the retrieval of multimedia information, are introduced to realize fine-grained and precise environment surveillance. In this paper, a framework for designing underground coalmine WMSNs based on Multi-Band Orthogonal Frequency-Division Multiplexing Ultra-wide Band (MB-OFDM-UWB) is presented. The selection of MB-OFDM-UWB wireless transmission solution is based on the characteristics of underground coalmines. Network structure and design challenges are analyzed first, which is the foundation for further discussion. Then, key supporting technologies and open research areas in different layers are surveyed, and we provide a detailed literature review of the state of the art strategies, algorithms and general solutions in these issues. Finally, other research issues like localization, information processing, and network management are discussed.

Multimedia Workstations: Electronic Assistants for Health-Care Professionals.

PubMed

Degoulet, P; Jean, F-C; Safran, C

1996-01-01

The increasing costs of health care and the economic reality has produced an interesting paradox for the health professional to perform more clinical work with fewer support personnel. Moreover, an explosion of the knowledge-base that underlies sound clinical care not only makes effective time management critical, but also knowledge management compelling. A multimedia workstation is an electronic assistant for the busy health professional that can help with administrative tasks and give access to clinical information and knowledge networks. The multimedia nature of processed information reflects an evolution of medical technologies that involve more and more complex objects such as video sequences or digitized signals. Analysis of the 445 Medline-indexed publications for the January 1991 to December 1994 period, that included the word "workstation" either in their title or in their abstract, helps in refining objectives and challenges both for health professionals and decision makers. From an engineering perspective, development of a workstation requires the integration into the same environments of tools to localize, access, manipulate and communicate the required information. The long-term goal is to establish an easy access in a collaborative working environment that gives the end-user the feeling of a single virtual health enterprise, driven by an integrated computer system when the information system relies on a set of heterogeneous and geographically distributed components. Consequences in terms of migration from traditional client/server architectures to more client/network architectures are considered.

Poor participant comprehension of research procedures following the conventional face-to-face consent process for biomedical research is common. We describe the development of a multimedia informed consent video and website that incorporates cognitive strategies to enhance comprehension of study related material directed to parents and adolescents. A multidisciplinary team was assembled for development of the video and website that included human subjects professionals; psychologist researchers; institutional video and web developers; bioinformaticians and programmers; and parent and adolescent stakeholders. Five learning strategies that included Sensory-Modality view, Coherence, Signaling, Redundancy, and Personalization were integrated into a 15-min video and website material that describes a clinical research trial. A diverse team collaborated extensively over 15months to design and build a multimedia platform for obtaining parental permission and adolescent assent for participant in as asthma clinical trial. Examples of the learning principles included, having a narrator describe what was being viewed on the video (sensory-modality); eliminating unnecessary text and graphics (coherence); having the initial portion of the video explain the sections of the video to be viewed (signaling); avoiding simultaneous presentation of text and graphics (redundancy); and having a consistent narrator throughout the video (personalization). Existing conventional and multimedia processes for obtaining research informed consent have not actively incorporated basic principles of human cognition and learning in the design and implementation of these processes. The present paper illustrates how this can be achieved, setting the stage for rigorous evaluation of potential benefits such as improved comprehension, satisfaction with the consent process, and completion of research objectives. New consent strategies that have an integrated cognitive approach need to be developed and tested in controlled trials. Copyright © 2017 Elsevier Inc. All rights reserved.

Improving understanding in the research informed consent process: a systematic review of 54 interventions tested in randomized control trials

2013-01-01

Background Obtaining informed consent is a cornerstone of biomedical research, yet participants comprehension of presented information is often low. The most effective interventions to improve understanding rates have not been identified. Purpose To systematically analyze the random controlled trials testing interventions to research informed consent process. The primary outcome of interest was quantitative rates of participant understanding; secondary outcomes were rates of information retention, satisfaction, and accrual. Interventional categories included multimedia, enhanced consent documents, extended discussions, test/feedback quizzes, and miscellaneous methods. Methods The search spanned from database inception through September 2010. It was run on Ovid MEDLINE, Ovid EMBASE, Ovid CINAHL, Ovid PsycInfo and Cochrane CENTRAL, ISI Web of Science and Scopus. Five reviewers working independently and in duplicate screened full abstract text to determine eligibility. We included only RCTs. 39 out of 1523 articles fulfilled review criteria (2.6%), with a total of 54 interventions. A data extraction form was created in Distiller, an online reference management system, through an iterative process. One author collected data on study design, population, demographics, intervention, and analytical technique. Results Meta-analysis was possible on 22 interventions: multimedia, enhanced form, and extended discussion categories; all 54 interventions were assessed by review. Meta-analysis of multimedia approaches was associated with a non-significant increase in understanding scores (SMD 0.30, 95% CI, -0.23 to 0.84); enhanced consent form, with significant increase (SMD 1.73, 95% CI, 0.99 to 2.47); and extended discussion, with significant increase (SMD 0.53, 95% CI, 0.21 to 0.84). By review, 31% of multimedia interventions showed significant improvement in understanding; 41% for enhanced consent form; 50% for extended discussion; 33% for test/feedback; and 29% for miscellaneous.Multiple sources of variation existed between included studies: control processes, the presence of a human proctor, real vs. simulated protocol, and assessment formats. Conclusions Enhanced consent forms and extended discussions were most effective in improving participant understanding. Interventions of all categories had no negative impact on participant satisfaction or study accrual. Identification of best practices for studies of informed consent interventions would aid future systematic comparisons. PMID:23879694

Worksite-based internet multimedia program for family caregivers of persons with dementia.

PubMed

Beauchamp, Natasha; Irvine, A Blair; Seeley, John; Johnson, Brian

2005-12-01

Our goal was to evaluate the efficacy of a multimedia support program delivered over the Internet to employed family caregivers of persons with dementia. The evaluation of this program involved 299 employed family caregivers participating in a pretest-posttest randomized clinical trial with a 30-day follow-up and a waitlist control condition. Validated instruments include the Center for Epidemiologic Studies-Depression scale, the State-Trait Anxiety Inventory, the Caregiver Strain scale from Benjamin Rose, and Positive Aspects of Caregiving used in the nationwide REACH study. Those who viewed Caregiver's Friend: Dealing with Dementia 30 days postexposure demonstrated significant improvements in depression, anxiety, level and frequency of stress, caregiver strain, self-efficacy, and intention to seek help, as well as perceptions of positive aspects of caregiving. Interactive multimedia interventions delivered over the Internet appear to be uniquely suited to provide low-cost, effective, convenient, individually tailored programs that present educational information, cognitive and behavioral skills, and affective learning opportunities. This makes Web-based multimedia a promising avenue for work-life balance programs, employee-assistance providers, and organizations interested in improving family caregiver health and well-being.

The purpose of this study is to determine the effectiveness of multimedia educational tools to improve CT planning preparation for intensity modulated radiotherapy (IMRT) for prostate cancer. Many patients are not prepared when given verbal preparation instructions to have a full bladder and empty rectum for their IMRT and require being rescanned, which results in additional costs for the patient and the hospital. A pamphlet and video outlining the proper preparation for prostate IMRT was created to decrease additional scans and the associated costs, while increasing patient satisfaction. A controlled, randomized experimental group study was conducted to examine the effectiveness of the multimedia tools (the video and the pamphlet), as compared to the pamphlet only, in preparing patients for their planning CT appointment. We found no statistical difference between the multimedia group and the pamphlet group in patients' preparedness for their appointments and the rescanning rate. However, patients in the multimedia group indicated that they felt more prepared about their treatment after watching the video and stated that they would recommend the video to other patients with prostate cancer. Furthermore, patients who had to wait longer for their planning CT appointment felt less prepared by the materials than those with a shorter wait time. We recommend reducing wait times between appointments as much as possible to increase patients' preparedness for the planning CT. We conclude that providing multimedia treatment information and minimizing wait times increases patients' feelings of preparedness leading to a more positive treatment experience and reducing costly rescans.

Clinical challenges associated with incorporation of nonradiology images into the electronic medical record

NASA Astrophysics Data System (ADS)

Siegel, Eliot L.; Reiner, Bruce I.

2001-08-01

To date, the majority of Picture Archival and Communication Systems (PACS) have been utilized only for capture, storage, and display of radiology and in some cases, nuclear medicine images. Medical images for other subspecialty areas are currently stored in local, independent systems, which typically are not accessible throughout the healthcare enterprise and do not communicate with other hospital information or image management systems. It is likely that during the next few years, healthcare centers will expand PAC system capability to incorporate these multimedia data or alternatively, hospital-wide electronic patient record systems will be able to provide this function.

Pilot study in the development of an interactive multimedia learning environment for sexual health interventions: a focus group approach.

In the UK there are high rates of sexually transmitted infections and unintended pregnancies amongst young people. There is limited and contradictory evidence that current sexual health education interventions are effective or that they improve access to appropriate sexual health services. This paper describes the outcome of focus group work with young people that was undertaken to inform the design of an Interactive Multimedia Learning Environment that incorporates message framing, intended for use in sexual health promotion. The focus group work addressed sexual attitudes, behaviour, risk perception, and knowledge of sexual health and sexual health services in Nottingham. The results provided new insights into young peoples' sexual behaviour, and their diversity of knowledge and beliefs. Common themes expressed regarding sexual health services included concerns about confidentiality, lack of confidence to access services and fear of the unknown. The results showed that while the adolescents are reasonably knowledgeable about infection, they do not know as much about the relevant services to treat it. This work emphasizes the need for user involvement throughout the design and development of a sexual health intervention, and will form the basis of the next part of the project.

LEGO-MM: LEarning structured model by probabilistic loGic Ontology tree for MultiMedia.

2016-09-22

Recent advances in Multimedia ontology have resulted in a number of concept models, e.g., LSCOM and Mediamill 101, which are accessible and public to other researchers. However, most current research effort still focuses on building new concepts from scratch, very few work explores the appropriate method to construct new concepts upon the existing models already in the warehouse. To address this issue, we propose a new framework in this paper, termed LEGO1-MM, which can seamlessly integrate both the new target training examples and the existing primitive concept models to infer the more complex concept models. LEGOMM treats the primitive concept models as the lego toy to potentially construct an unlimited vocabulary of new concepts. Specifically, we first formulate the logic operations to be the lego connectors to combine existing concept models hierarchically in probabilistic logic ontology trees. Then, we incorporate new target training information simultaneously to efficiently disambiguate the underlying logic tree and correct the error propagation. Extensive experiments are conducted on a large vehicle domain data set from ImageNet. The results demonstrate that LEGO-MM has significantly superior performance over existing state-of-the-art methods, which build new concept models from scratch.

Over the past few years, Session Initiation Protocol (SIP) is found as a substantial application-layer protocol for the multimedia services. It is extensively used for managing, altering, terminating and distributing the multimedia sessions. Authentication plays a pivotal role in SIP environment. Currently, Lu et al. presented an authentication protocol for SIP and profess that newly proposed protocol is protected against all the familiar attacks. However, the detailed analysis describes that the Lu et al.'s protocol is exposed against server masquerading attack and user's masquerading attack. Moreover, it also fails to protect the user's identity as well as it possesses incorrect login and authentication phase. In order to establish a suitable and efficient protocol, having ability to overcome all these discrepancies, a robust ECC-based novel mutual authentication mechanism with anonymity for SIP is presented in this manuscript. The improved protocol contains an explicit parameter for user to cope the issues of security and correctness and is found to be more secure and relatively effective to protect the user's privacy, user's masquerading and server masquerading as it is verified through the comprehensive formal and informal security analysis.

Health education and multimedia learning: educational psychology and health behavior theory (Part 1).

PubMed

Mas, Francisco G Soto; Plass, Jan; Kane, William M; Papenfuss, Richard L

2003-07-01

When health education researchers began to investigate how individuals make decisions related to health and the factors that influence health behaviors, they referred to frameworks shared by educational and learning research. Health education adopted the basic principles of the cognitive revolution, which were instrumental in advancing the field. There is currently a new challenge to confront: the widespread use of new technologies for health education. To better overcome this challenge, educational psychology and instructional technology theory should be considered. Unfortunately, the passion to incorporate new technologies too often overshadows how people learn or, in particular, how people learn through computer technologies. This two-part article explains how educational theory contributed to the early development of health behavior theory, describes the most relevant multimedia learning theories and constructs, and provides recommendations for developing multimedia health education programs and connecting theory and practice.

The paper is a presentation of the current state of development for the Atlas of Physiology and Pathophysiology (Atlas). Our main aim is to provide a novel interactive multimedia application that can be used for biomedical education where (a) simulations are combined with tutorials and (b) the presentation layer is simplified while the underlying complexity of the model is retained. The development of the Atlas required the cooperation of many professionals including teachers, system analysts, artists, and programmers. During the design of the Atlas, tools were developed that allow for component-based creation of simulation models, creation of interactive multimedia and their final coordination into a compact unit based on the given design. The Atlas is a freely available online application, which can help to explain the function of individual physiological systems and the causes and symptoms of their disorders.

Computer-based multimedia presentations employing animated agents (avatars) can positively impact perceptions about engineering; the current research advances our understanding of this effect to pre-college populations, the main target for engineering outreach. The study examines the effectiveness of a brief computer-based intervention with animated agents in improving perceptions about engineering. Five hundred sixty-five elementary, middle-, and high-school students in the southwestern USA viewed a short computer-based multimedia overview of four engineering disciplines (electrical, chemical, biomedical, and environmental) with embedded animated agents. Students completed identical surveys measuring five subscales of engineering perceptions immediately before and after the intervention. Analyses of pre- and post-surveys demonstrated that the computer presentation significantly improved perceptions for each student group, and that effects were stronger for elementary school students, compared to middle- and high-school students.

The practice of medicine, with its wide range of environmental conditions and complex dependencies, has long been used as a test bed for various advanced technologies. Telemedicine, as conceptualised within the Multimedia Super Corridor (MSC) context, is seen as the application of several relatively mature technologiesartificial intelligence (AI), multimedia communication and information systems (IS) amongst othersso as to benefit a large cross-section of the Malaysian population. We will discuss in general terms the Malaysian vision on the comprehensive MSC telemedicine solution, its functionality and associated operational conditions. In particular, this paper focuses on the conceptualisation of one key telemedical component i.e. the Lifetime Health Plan (LHP) system, which is eventually intended to be a distributed multi-module application for the periodic monitoring and generation of health-care advisories for upwards of 20 million Malaysians.

This paper describes our perception of current developments in networking, telecommunication and technology of multimedia. As such, we have taken a constructive view. From this standpoint, we devised a client server architecture that veils servers from their customers. It adheres to our conviction that network and location independence for serve access is a future trend. We have constructed an on-line KARAOKE on an existing CVS (Chinese Videotex System) to test the workability of this architecture and it works well. We are working on a prototype multimedia service network which is a miniature client server structure of our proposal. A specially designed protocol is described. Through this protocol, an one-to-many connection can be set up and to provide for multimedia applications, new connections can be established within a basic connection. So continuous media may have their own connections without being interrupted by other media, at least from the view of an application. We have advanced a constructive view which is not a framework itself. But it is tantamount to a framework, in building systems as assembly of methods, technics, designs, and ideas. This is what a framework does with more flexibility and availability.

Multimedia consultation session recording and playback using Java-based browser in global PACS

Martinez, Ralph; Shah, Pinkesh J.; Yu, Yuan-Pin

1998-07-01

The current version of the Global PACS software system uses a Java-based implementation of the Remote Consultation and Diagnosis (RCD) system. The Java RCD includes a multimedia consultation session between physicians that includes text, static image, image annotation, and audio data. The JAVA RCD allows 2-4 physicians to collaborate on a patient case. It allows physicians to join the session via WWW Java-enabled browsers or stand alone RCD application. The RCD system includes a distributed database archive system for archiving and retrieving patient and session data. The RCD system can be used for store and forward scenarios, case reviews, and interactive RCD multimedia sessions. The RCD system operates over the Internet, telephone lines, or in a private Intranet. A multimedia consultation session can be recorded, and then played back at a later time for review, comments, and education. A session can be played back using Java-enabled WWW browsers on any operating system platform. The JAVA RCD system shows that a case diagnosis can be captured digitally and played back with the original real-time temporal relationships between data streams. In this paper, we describe design and implementation of the RCD session playback.

Management of ATM-based networks supporting multimedia medical information systems

1997-05-01

Medical information systems are acquiring the ability to collect and deliver many different types of medical information. In support of the increased network demands necessitated by these expanded capabilities, asynchronous transfer mode (ATM) based networks are being deployed in medical care systems. While ATM supplies a much greater line rate than currently deployed networks, the management and standards surrounding ATM are yet to mature. This paper explores the management and control issues surrounding an ATM network supporting medical information systems, and examines how management impacts network performance and robustness. A multivendor ATM network at the BJC Health System/Washington University and the applications using the network are discussed. Performance information for specific applications is presented and analyzed. Network management's influence on application reliability is outlined. The information collected is used to show how ATM network standards and management tools influence network reliability and performance. Performance of current applications using the ATM network is discussed. Special attention is given to issues encountered in implementation of hypertext transfer protocol over ATM internet protocol (IP) communications. A classical IP ATM implementation yields greater than twenty percent higher network performance over LANE. Maximum performance for a host's suite of applications can be obtained by establishing multiple individually engineered IP links through its ATM network connection.

MPS Internships in Public Science Education: Sensing the Radio Sky

The intent of the “Sensing the Radio Sky” program is to teach high school students the concepts and relevance of radio astronomy through presentations in STARLAB portable planetariums. The two year program began in the summer of 2004 and was completed in December 2006. The program involved a team of 12 undergraduate physics and multimedia majors and four faculty mentors from Furman University, University of North Carolina-Asheville and Pisgah Astronomical Research Institute (PARI). One component of the program is the development and production of a projection cylinder for the portable STARLAB planetariums. The cylinder gives a thorough view of the Milky Way and of several other celestial sources in radio wavelengths, yet these images are difficult to perceive without prior knowledge of radio astronomy. Consequently, the Radio Sky team created a multimedia presentation to accompany the cylinder. This multimedia component contains six informative lessons on radio astronomy assembled by the physics interns and numerous illustrations and animations created by the multimedia interns. The cylinder and multimedia components complement each other and provide a unique, thorough, and highly intelligible perspective on radio astronomy. The final draft is complete and will be sent to Learning Technologies, Inc., for marketing to owners of STARLAB planetariums throughout the world. We acknowledge support from the NSF Internship in Public Science Education Program grant number 0324729.

To evaluate the effects of different patient education techniques on patients' anxiety levels before and after dental implant surgery. Sixty patients were randomized into three groups; each contained 20 patients; [group 1, basic information given verbally, with details of operation and recovery; group 2 (study group), basic information given verbally with details of operative procedures and recovery, and by watching a movie on single implant surgery]; and a control group [basic information given verbally "but it was devoid of the details of the operative procedures and recovery"]. Anxiety levels were assessed using the Spielberger's State-Trait Anxiety Inventory (STAI) and Modified Dental Anxiety Scale (MDAS). Pain was assessed with a visual analog scale (VAS). The most significant changes were observed in the movie group (P < 0.05). Patients who were more anxious also used more analgesic medication. Linear regression analysis showed that female patients had higher levels of anxiety (P < 0.05). Preoperative multimedia information increases anxiety level.

Evaluation of a multimedia information system for endoscopy

NASA Astrophysics Data System (ADS)

Enning, C. John W.; Siersema, Peter D.; van Blankenstein, Mark; van Boven, Gert-Jan; van Gennip, Elisabeth M.

1996-05-01

In a cooperation between the University Hospital Rotterdam (AZR) and HISCOM, HIS supplier, a multimedia information system for endoscopy (ENSIS) has been developed in a project funded by the Dutch Ministry of Health Care. An integral part of this project was an evaluation of costs and effects of this system. The system has been implemented on the gastroenterology department and the internal medicine ward in the AZR. The results indicate that the anatomical knowledge of requesting physicians improved with the system. Both the response time and availability of endoscopy images improved greatly. Because of the use of off-the-shelve technology (possible because of the relatively small resolution requirements of endoscopy images) ENSIS can be implemented at relatively low costs.

Estimating Missing Features to Improve Multimedia Information Retrieval

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bagherjeiran, A; Love, N S; Kamath, C

Retrieval in a multimedia database usually involves combining information from different modalities of data, such as text and images. However, all modalities of the data may not be available to form the query. The retrieval results from such a partial query are often less than satisfactory. In this paper, we present an approach to complete a partial query by estimating the missing features in the query. Our experiments with a database of images and their associated captions show that, with an initial text-only query, our completion method has similar performance to a full query with both image and text features.more » In addition, when we use relevance feedback, our approach outperforms the results obtained using a full query.« less

Design and management of public health outreach using interoperable mobile multimedia: an analysis of a national winter weather preparedness campaign.

PubMed

Bandera, Cesar

2016-05-25

The Office of Public Health Preparedness and Response (OPHPR) in the Centers for Disease Control and Prevention conducts outreach for public preparedness for natural and manmade incidents. In 2011, OPHPR conducted a nationwide mobile public health (m-Health) campaign that pushed brief videos on preparing for severe winter weather onto cell phones, with the objective of evaluating the interoperability of multimedia m-Health outreach with diverse cell phones (including handsets without Internet capability), carriers, and user preferences. Existing OPHPR outreach material on winter weather preparedness was converted into mobile-ready multimedia using mobile marketing best practices to improve audiovisual quality and relevance. Middleware complying with opt-in requirements was developed to push nine bi-weekly multimedia broadcasts onto subscribers' cell phones, and OPHPR promoted the campaign on its web site and to subscribers on its govdelivery.com notification platform. Multimedia, text, and voice messaging activity to/from the middleware was logged and analyzed. Adapting existing media into mobile video was straightforward using open source and commercial software, including web pages, PDF documents, and public service announcements. The middleware successfully delivered all outreach videos to all participants (a total of 504 videos) regardless of the participant's device. 54 % of videos were viewed on cell phones, 32 % on computers, and 14 % were retrieved by search engine web crawlers. 21 % of participating cell phones did not have Internet access, yet still received and displayed all videos. The time from media push to media viewing on cell phones was half that of push to viewing on computers. Video delivered through multimedia messaging can be as interoperable as text messages, while providing much richer information. This may be the only multimedia mechanism available to outreach campaigns targeting vulnerable populations impacted by the digital divide. Anti-spam laws preserve the integrity of mobile messaging, but complicate campaign promotion. Person-to-person messages may boost enrollment.

Kononowicz, Andrzej A; Zary, Nabil; Davies, David; Heid, Jörn; Woodham, Luke; Hege, Inga

2011-01-01

Patient consents for distribution of multimedia constitute a significant element of medical case-based repositories in medicine. A technical challenge is posed by the right of patients to withdraw permission to disseminate their images or videos. A technical mechanism for spreading information about changes in multimedia usage licenses is sought. The authors gained their experience by developing and managing a large (>340 cases) repository of virtual patients within the European project eViP. The solution for dissemination of license status should reuse and extend existing metadata standards in medical education. Two methods: PUSH and PULL are described differing in the moment of update and the division of responsibilities between parties in the learning object exchange process. The authors recommend usage of the PUSH scenario because it is better adapted to legal requirements in many countries. It needs to be stressed that the solution is based on mutual trust of the exchange partners and therefore is most appropriate for use in educational alliances and consortia. It is hoped that the proposed models for exchanging consents and licensing information will become a crucial part of the technical frameworks for building case-based repositories.

The use of computer technology for patient education has increased in recent years. This article describes a study that measures the attitudes and perceptions of healthcare professionals and laypeople regarding the effectiveness of a multimedia computer, the Brain Injury Resource Center (BIRC), as an educational tool. The study focused on three major themes: (a) usefulness of the information presented, (b) effectiveness of the multimedia touch-screen computer methodology, and (c) the appropriate time for making this resource available. This prospective study, conducted in an acute care medical center, obtained healthcare professionals' evaluations using a written survey and responses from patients with brain injury and their families during interviews. The findings have yielded excellent ratings as to the ease of understanding and usefulness of the BIRC. By using sight, sound, and touch, such a multimedia learning center has the potential to simplify patient and family education.

General formulation of characteristic time for persistent chemicals in a multimedia environment

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bennett, D.H.; McKone, T.E.; Kastenberg, W.E.

1999-02-01

A simple yet representative method for determining the characteristic time a persistent organic pollutant remains in a multimedia environment is presented. The characteristic time is an important attribute for assessing long-term health and ecological impacts of a chemical. Calculating the characteristic time requires information on decay rates in multiple environmental media as well as the proportion of mass in each environmental medium. The authors explore the premise that using a steady-state distribution of the mass in the environment provides a means to calculate a representative estimate of the characteristic time while maintaining a simple formulation. Calculating the steady-state mass distributionmore » incorporates the effect of advective transport and nonequilibrium effects resulting from the source terms. Using several chemicals, they calculate and compare the characteristic time in a representative multimedia environment for dynamic, steady-state, and equilibrium multimedia models, and also for a single medium model. They demonstrate that formulating the characteristic time based on the steady-state mass distribution in the environment closely approximates the dynamic characteristic time for a range of chemicals and thus can be used in decisions regarding chemical use in the environment.« less

The modality and redundancy effects in multimedia learning in children with dyslexia.

2018-05-01

The present study aimed to examine the modality and redundancy effects in multimedia learning in children with dyslexia in order to find out whether their learning benefits from written and/or spoken text with pictures. We compared study time and knowledge gain in 26 11-year-old children with dyslexia and 38 typically reading peers in a within-subjects design. All children were presented with a series of user-paced multimedia lessons in 3 conditions: pictorial information presented with (a) written text, (b) audio, or (c) combined text and audio. We also examined whether children's learning outcomes were related to their working memory. With respect to study time, we found modality and reversed redundancy effects. Children with dyslexia spent more time learning in the text condition, compared with the audio condition and the combined text-and-audio condition. Regarding knowledge gain, no modality or redundancy effects were evidenced. Although the groups differed on working memory, it did not influence the modality or redundancy effect on study time or knowledge gain. In multimedia learning, it thus is more efficient to provide children with dyslexia with audio or with auditory support. Copyright © 2018 John Wiley & Sons, Ltd.

Database technology and the management of multimedia data in the Mirror project

NASA Astrophysics Data System (ADS)

de Vries, Arjen P.; Blanken, H. M.

1998-10-01

Multimedia digital libraries require an open distributed architecture instead of a monolithic database system. In the Mirror project, we use the Monet extensible database kernel to manage different representation of multimedia objects. To maintain independence between content, meta-data, and the creation of meta-data, we allow distribution of data and operations using CORBA. This open architecture introduces new problems for data access. From an end user's perspective, the problem is how to search the available representations to fulfill an actual information need; the conceptual gap between human perceptual processes and the meta-data is too large. From a system's perspective, several representations of the data may semantically overlap or be irrelevant. We address these problems with an iterative query process and active user participating through relevance feedback. A retrieval model based on inference networks assists the user with query formulation. The integration of this model into the database design has two advantages. First, the user can query both the logical and the content structure of multimedia objects. Second, the use of different data models in the logical and the physical database design provides data independence and allows algebraic query optimization. We illustrate query processing with a music retrieval application.

2017-10-16

Twenty-five years after the Americans with Disabilities Act, there has still been a lack of advancement of accessibility in healthcare for people with visual impairments, particularly older adults with low vision. This study aims to advance understanding of how older adults with low vision obtain, process, and use health information and services, and to seek opportunities of information technology to support them. A convenience sample of 10 older adults with low vision participated in semi-structured phone interviews, which were audio-recorded and transcribed verbatim for analysis. Participants shared various concerns in accessing, understanding, and using health information, care services, and multimedia technologies. Two main themes and nine subthemes emerged from the analysis. Due to the concerns, older adults with low vision tended to fail to obtain the full range of all health information and services to meet their specific needs. Those with low vision still rely on residual vision such that multimedia-based information which can be useful, but it should still be designed to ensure its accessibility, usability, and understandability.

Digital multimedia books produced using iBooks Author for pre-operative surgical patient information.

2014-10-01

Presenting patients with medical information and ensuring informed consent can be difficult due to patients with varying levels of literacy, physical and mental disabilities and spoken languages. Patients obtaining information from external sources, such as the internet, can also be problematic as the information can be irrelevant, inaccurate or misleading. A patient satisfaction study was performed in order to assess the effectiveness of using ebooks in order to communicate pre and post surgical information to neurosurgical patients. 3 digital books were produced using iBooks Author (a free desktop publishing program designed by Apple) including ACDF (anterior cervical discectomy and fusion), lumbar laminectomy and lumbar discectomy. Each book contained written information organised into sections and chapters along with an array of multimedia elements including 3D animations, interactive diagrams, 3D models of anatomy and patient experience videos. 32 volunteer patients were then presented with the digital books via an iPad during their preoperative assessment and then asked to complete a questionnaire. The results demonstrated a demand for this type of digital presentation of medical information and also showed patients no longer felt the need to seek further information from external sources.

The promise and challenge of including multimedia items in medical licensure examinations: some insights from an empirical trial.

PubMed

Shen, Linjun; Li, Feiming; Wattleworth, Roberta; Filipetto, Frank

2010-10-01

The Comprehensive Osteopathic Medical Licensing Examination conducted a trial of multimedia items in the 2008-2009 Level 3 testing cycle to determine (1) if multimedia items were able to test additional elements of medical knowledge and skills and (2) how to develop effective multimedia items. Forty-four content-matched multimedia and text multiple-choice items were randomly delivered to Level 3 candidates. Logistic regression and paired-samples t tests were used for pairwise and group-level comparisons, respectively. Nine pairs showed significant differences in either difficulty or/and discrimination. Content analysis found that, if text narrations were less direct, multimedia materials could make items easier. When textbook terminologies were replaced by multimedia presentations, multimedia items could become more difficult. Moreover, a multimedia item was found not uniformly difficult for candidates at different ability levels, possibly because multimedia and text items tested different elements of a same concept. Multimedia items may be capable of measuring some constructs different from what text items can measure. Effective multimedia items with reasonable psychometric properties can be intentionally developed.

In this paper, we present the methodology we adopted in designing and developing an object-oriented database system for the management of medical records. The designed system provides technical solutions to important requirements of most clinical information systems, such as 1) the support of tools to create and manage views on data and view schemas, offering to different users specific perspectives on data tailored to their needs; 2) the capability to handle in a suitable way the temporal aspects related to clinical information; and 3) the effective integration of multimedia data. Remote data access for authorized users is also considered. As clinical application, we describe here the prototype of a user-oriented clinical information system for the archiving and the management of multimedia and temporally oriented clinical data related to percutaneous transluminal coronary angioplasty (PTCA) patients. Suitable view schemas for various user roles (cath-lab physician, ward nurse, general practitioner) have been modeled and implemented on the basis of a detailed analysis of the considered clinical environment, carried out by an object-oriented approach.

With the rapid development of science and technology, large-scale rehabilitation centers and clinical rehabilitation trials usually involve significant volumes of multimedia data. Due to the global aging crisis, millions of new patients with age-related chronic diseases will produce huge amounts of data and contribute to soaring costs of medical care. Hence, a solution for effective data management and decision support will significantly reduce the expenditure and finally improve the patient life quality. Inspired from the concept of the electronic patient record (ePR), we developed a prototype system for the field of rehabilitation engineering. The system is subject or patient-oriented and customized for specific projects. The system components include data entry modules, multimedia data presentation and data retrieval. To process the multimedia data, the system includes a DICOM viewer with annotation tools and video/audio player. The system also serves as a platform for integrating decision-support tools and data mining tools. Based on the prototype system design, we developed two specific applications: 1) DOSE (a phase 1 randomized clinical trial to determine the optimal dose of therapy for rehabilitation of the arm and hand after stroke.); and 2) NEXUS project from the Rehabilitation Engineering Research Center(RERC, a NIDRR funded Rehabilitation Engineering Research Center). Currently, the system is being evaluated in the context of the DOSE trial with a projected enrollment of 60 participants over 5 years, and will be evaluated by the NEXUS project with 30 subjects. By applying the ePR concept, we developed a system in order to improve the current research workflow, reduce the cost of managing data, and provide a platform for the rapid development of future decision-support tools.

Teacher experiences in the use of the "Zoology Zone" multimedia resource in elementary science

NASA Astrophysics Data System (ADS)

Paradis, Lynne Darlene

This interpretive research study explored the experiences of teachers with the use of the Zoology Zone multimedia resource in teaching grade three science. Four generalist teachers used the multimedia resource in the teaching of the Animal Life Cycle topic from the Alberta grade three science program. The experiences of the teachers were examined through individual interviews, classroom visits and group interviews. Three dimensions of the study, as they related to elementary science teaching using the Zoology Zone multimedia resource were examined: (a) technology as a teaching resource, (b) science education and constructivist theory, and (c) teacher learning. In the area of planning for instruction, the teachers found that using the multimedia resource demanded more time and effort than using non-computer resources because of the dependence teachers had on others for ensuring access to computer labs and setting up the multimedia resource to run on school computers. The teachers felt there was value in giving students the opportunity to independently explore the multimedia resource because it captured their attention, included appropriate content, and was designed so that students could navigate through the teaming activities easily and make choices about how to proceed with their own learning. Despite the opportunities for student directed learning, the teachers found that it was also necessary to include some teacher directed learning to ensure that students were learning the mandated curriculum. As the study progressed, it became evident that the teachers valued the social dimensions of learning by making it a priority to include lessons that encouraged student to student interaction, student to teacher interaction, small group and whole class discussion, and peer teaching. When students were engaged with the multimedia resource, the teacher facilitated learning by circulating to each student and discussing student findings. Teachers focussed primarily on the content components of the Alberta science program of studies. They stated that the time allotted for science instruction was insufficient to effectively address the teaching of skills for science inquiry and of the 'big' ideas in science. The teachers stated that they valued inquiry teaching, constructivist teaching and the integration of the Information and Communication Technology (ICT) outcomes but that utilizing these teaching approaches was challenging because of the depth and breadth of the mandated curriculum. It became apparent that science instruction did not meet all the expectations of the mandated science curriculum and that the teachers did not plan for the integration of the ICT outcomes. The teachers in the study stated that they felt that multimedia resources did have a place in the elementary science curriculum and that the ICT outcomes could be achieved as part of science instruction using the Zoology Zone multimedia resource. The study concludes with some implications for teachers, educational policy makers and school administration, related to the use of multimedia resources in the teaching of elementary science and in the teaching of the ICT outcomes.

Dialog detection in narrative video by shot and face analysis

NASA Astrophysics Data System (ADS)

Kroon, B.; Nesvadba, J.; Hanjalic, A.

2007-01-01

The proliferation of captured personal and broadcast content in personal consumer archives necessitates comfortable access to stored audiovisual content. Intuitive retrieval and navigation solutions require however a semantic level that cannot be reached by generic multimedia content analysis alone. A fusion with film grammar rules can help to boost the reliability significantly. The current paper describes the fusion of low-level content analysis cues including face parameters and inter-shot similarities to segment commercial content into film grammar rule-based entities and subsequently classify those sequences into so-called shot reverse shots, i.e. dialog sequences. Moreover shot reverse shot specific mid-level cues are analyzed augmenting the shot reverse shot information with dialog specific descriptions.

Practical and generalizable architecture for an intelligent tutoring system

NASA Astrophysics Data System (ADS)

Kaplan, Randy M.; Trenholm, Harriet

1993-03-01

In this paper we describe an intelligent tutoring system (ITS) called HYDRIVE (hydraulics interactive video experience). This system is built using several novel approaches to intelligent tutoring. The underlying rationale for HYDRIVE is based on the results of a cognitive task analysis. The reasoning component of the system makes extensive use of a hierarchical knowledge representation. Reasoning within the system is accomplished using a logic-based approach and is linked to a highly interactive interface using multimedia. The knowledge representation contains information that drives the multimedia elements of the system, and the reasoning components select the appropriate information to assess student knowledge or guide the student at any particular moment. As this system will be deployed throughout the Air Force maintenance function, the implementation platform is the IBM PC.

Diverse application areas are increasingly relying on multimedia understanding systems. Advances in multimedia understanding are related directly to advances in signal processing, computer vision, pattern recognition, multimedia databases, and smart sensors. We review the state-of-the-art techniques in multimedia retrieval. In particular, we discuss how multimedia retrieval can be viewed as a pattern recognition problem. We discuss how reliance on powerful pattern recognition and machine learning techniques is increasing in the field of multimedia retrieval. We review the state-of-the-art multimedia understanding systems with particular emphasis on a system for semantic video indexing centered around multijects and multinets. We discuss how semantic retrieval is centered around concepts and context and the various mechanisms for modeling concepts and context.

A cancer diagnosis is highly distressing. Yet, to make informed treatment choices patients have to learn complicated disease and treatment information that is often fraught with medical and statistical terminology. Thus, patients need accurate and easy-to-understand information. To introduce the development and preliminary evaluation through focus groups of a novel highly-interactive multimedia-education software program for patients diagnosed with localized prostate cancer. The prostate interactive education system uses the metaphor of rooms in a virtual health center (ie, reception area, a library, physician offices, group meeting room) to organize information. Text information contained in the library is tailored to a person's information-seeking preference (ie, high versus low information seeker). We conducted a preliminary evaluation through 5 separate focus groups with prostate cancer survivors (N = 18) and their spouses (N = 15). Focus group results point to the timeliness and high acceptability of the software among the target audience. Results also underscore the importance of a guide or tutor who assists in navigating the program and who responds to queries to facilitate information retrieval. Focus groups have established the validity of our approach and point to new directions to further enhance the user interface.

An improved quality of life through education and developmental communication is an important necessity of societal up-liftment in the new millennium, especially in the developing nations. The population explosion and the associated pressure on the scarce resources to meet the basic necessities have made it more or less impossible for most of the nations to invest reasonable resources in realizing adequate channels of formal education. Thanks to the developments in satellite communication and associated technologies, new vistas are available today to provide education and developmental communication opportunities to millions of people, spread across the globe. Satellite based Digital Audio and Multimedia Broadcasting is one such new development that is being viewed as an innovative space application in the coming decades. The potential of DAB technology to reach education, information and entertainment directly to the user through a specially designed receiver could be efficiently utilized by the developing nations to overcome their difficulties in realizing formal channels of education and information dissemination. WorldSpace plans to launch three geo-stationary satellites that would cover most of the developing economies in Africa, the Mediterranean, the Middle East, Asia, Latin America and the Caribbean. Apart from a variety of digital, high quality audio channels providing news, views, education and entertainment opportunities, the end users can also get a responsive multimedia. The multimedia is being planned as a specially packaged offering that can meet the demand of students, professionals as well as certain special groups who have certain specific data and information requirements. Apart from WorldSpace, renowned agencies/firms from different parts of the world shall provide the required content to meet these requirements. Though the Internet option is available, higher telephone charges and the difficulty in getting access have made this option less interesting and unpopular in most of the developing countries. The proposed digital audio and multimedia offering from WorldSpace to millions of consumers spread across more than 120 countries is considered as a unique tool for education and development, particularly in the developing nations. In this paper, an attempt is made to briefly describe the issues associated with education and development in developing countries, the WorldSpace offering and how a developing nation can benefit from this offering in the coming decades.

Radiology reports are the major, and often only, means of communication between radiologists and their referring clinicians. The purposes of this study are to identify referring physicians' preferences about radiology reports and to quantify their perceived value of multimedia reports (with embedded images) compared with narrative text reports. We contacted 1800 attending physicians from a range of specialties at large tertiary care medical center via e-mail and a hospital newsletter linking to a 24-question electronic survey between July and November 2012. One hundred sixty physicians responded, yielding a response rate of 8.9%. Survey results were analyzed using Statistical Analysis Software (SAS Institute Inc, Cary, NC). Of the 160 referring physicians respondents, 142 (89%) indicated a general interest in reports with embedded images and completed the remainder of the survey questions. Of 142 respondents, 103 (73%) agreed or strongly agreed that reports with embedded images could improve the quality of interactions with radiologists; 129 respondents (91%) agreed or strongly agreed that having access to significant images enhances understanding of a text-based report; 110 respondents (77%) agreed or strongly agreed that multimedia reports would significantly improve referring physician satisfaction; and 85 respondents (60%) felt strongly or very strongly that multimedia reports would significantly improve patient care and outcomes. Creating accessible, readable, and automatic multimedia reports should be a high priority to enhance the practice and satisfaction of referring physicians, improve patient care, and emphasize the critical role radiology plays in current medical care.

2003-12-01

Introduction by the column editor: In this final column of the year, Dr. Taintor provides an overview of exciting technological developments via his report on the 2003 annual meeting of the American Association for Technology in Psychiatry (AATP). Advances-and convergences-in technology are providing clinicians with increasingly useful tools to enhance the effectiveness of their treatments, increase access to care, reduce errors, and save time. As Dr. Taintor notes, AATP's meeting is traditionally held in conjunction with the annual meeting of the American Psychiatric Association (APA). I hope that his report will encourage APA's members to attend some of next year's informative sessions.

We describe the architecture and implementation of our comprehensive multi-platform collaboration framework known as Columbia InterNet Extensible Multimedia Architecture (CINEMA). It provides a distributed architecture for collaboration using synchronous communications like multimedia conferencing, instant messaging, shared web-browsing, and asynchronous communications like discussion forums, shared files, voice and video mails. It allows seamless integration with various communication means like telephones, IP phones, web and electronic mail. In addition, it provides value-added services such as call handling based on location information and presence status. The paper discusses the media services needed for collaborative environment, the components provided by CINEMA and the interaction among those components.

Modernization and new technologies: Coping with the information explosion

Information has become a valuable and strategic resource in all societies and economies. Scientific and technical information is especially important in developing and maintaining a strong national science and technology base. The expanding use of information technology, the growth of interdisciplinary research, and an increase in international collaboration are changing characteristics of information. This modernization effort applies new technology to current processes to provide near-term benefits to the user. At the same time, we are developing a long-term modernization strategy designed to transition the program to a multimedia, global 'library without walls'. Notwithstanding this modernization program, it is recogized that no one information center can hope to collect all the relevant data. We see information and information systems changing and becoming more international in scope. We are finding that many nations are expending resources on national systems which duplicate each other. At the same time that this duplication exists, many useful sources of aerospace information are not being collected to cover expanded sources of information. This paper reviews the NASA modernization program and raises for consideration new possibilities for unification of the various aerospace database efforts toward a cooperative international aerospace database initiative, one that can optimize the cost/benefit equation for all participants.

Standard print and verbal information provided to patients undergoing treatments are often difficult to understand and may impair their ability to be truly informed. This study examined the effect of an interactive multimedia informational program with in-line exercises and corrected feedback on patients' real-time understanding of their cardiac catheterization procedure. 151 adult patients scheduled for diagnostic cardiac catheterization were randomized to receive information about their procedure using either the standard institutional verbal and written information (SI) or an interactive iPad-based informational program (IPI). Subject understanding was evaluated using semi-structured interviews at baseline, immediately following catheterization, and 2 weeks after the procedure. In addition, for those randomized to the IPI, the ability to respond correctly to several in-line exercises was recorded. Subjects' perceptions of, and preferences for the information delivery were also elicited. Subjects randomized to the IPI program had significantly better understanding following the intervention compared with those randomized to the SI group (8.3±2.4 vs 7.4±2.5, respectively, 0-12 scale where 12=complete understanding, P<0.05). First-time correct responses to the in-line exercises ranged from 24.3% to 100%. Subjects reported that the in-line exercises were very helpful (9.1±1.7, 0-10 scale, where 10=extremely helpful) and the iPad program very easy to use (9.0±1.6, 0-10 scale, where 10=extremely easy) suggesting good clinical utility. Results demonstrated the ability of an interactive multimedia program to enhance patients' understanding of their medical procedure. Importantly, the incorporation of in-line exercises permitted identification of knowledge deficits, provided corrected feedback, and confirmed the patients' understanding of treatment information in real-time when consent was sought.

To identify the information needs of children with nocturnal enuresis, and to design, produce and evaluate an interactive computer program to provide this information. The program was developed over an 18-month period using information provided by children, parents and professionals, and was evaluated in a hospital-based enuresis clinic in 65 children. Usability and knowledge gained were also evaluated in 43 healthy children aged 8-10 years attending a local inner-city primary school. An interactive program about nocturnal enuresis was developed, which runs on a personal computer and uses sound, voice, cartoon drawings and animation in a modular design. Knowledge scores increased in clinic attendees and in schoolchildren after using the program (Wilcoxon matched pairs test, P < 0.001). This improvement was maintained when the program was re-tested 6-10 months later. This interactive computer program holds children's attention and increases their understanding of enuresis. Interactive multimedia may be useful to complement the information provided by health professionals. This method of communication may be particularly useful for children with a low level of literacy.

The emergence of high-speed networking for multimedia will have the effect of turning the computer screen into a window on a very large information space. As this information space increases in size and complexity, providing users with easy and intuitive means of accessing information will become increasingly important. Providing access to large amounts of text has been the focus of work for hundreds of years and has resulted in the evolution of a set of standards, from the Dewey Decimal System for libraries to the recently proposed ANSI standards for representing information on-line: KIF, Knowledge Interchange Format, and CG's, Conceptual Graphs. Certain problems remain unsolved by these efforts, though: how to let users know the contents of the information space, so that they know whether or not they want to search it in the first place, how to facilitate browsing, and, more specifically, how to facilitate visual browsing. These issues are particularly important for users in educational contexts and have been the focus of much of our recent work. In this paper we discuss some of the solutions we have prototypes: specifically, visual means, visual browsers, and visual definitional sequences.

1998-01-01

In support of satellite-ATM interoperability, researchers at the NASA Lewis Research Center performed asynchronous transfer mode (ATM) quality-of-service experiments using MPEG-2 (ATM application layer 5, AAL5) over ATM over an emulated satellite link. The purpose of these experiments was to determine the free-space link quality necessary to use the ATM protocol to transmit high-quality multimedia information. The experimental results have been submitted to various International Telecommunications Union (ITU) study groups in order to improve and modify current standards and recommendations for the telecommunications industry. Quality-of-service parameters for Class I, stringent class requirements for ITU-T I.356 are currently being debated. The experimental results presented will help to establish these quality-of-service thresholds. This material will also be useful in the development of the ITU-R WP-4B's Draft Preliminary New Recommendation on the Transmission of Asynchronous Transfer Mode Traffic via Satellite (Rec. S.atm).

Modernization of the NASA scientific and technical information program

Cotter, Gladys A.; Hunter, Judy F.; Ostergaard, K.

1993-01-01

The NASA Scientific and Technical Information Program utilizes a technology infrastructure assembled in the mid 1960s to late 1970s to process and disseminate its information products. When this infrastructure was developed it placed NASA as a leader in processing STI. The retrieval engine for the STI database was the first of its kind and was used as the basis for developing commercial, other U.S., and foreign government agency retrieval systems. Due to the combination of changes in user requirements and the tremendous increase in technological capabilities readily available in the marketplace, this infrastructure is no longer the most cost-effective or efficient methodology available. Consequently, the NASA STI Program is pursuing a modernization effort that applies new technology to current processes to provide near-term benefits to the user. In conjunction with this activity, we are developing a long-term modernization strategy designed to transition the Program to a multimedia, global 'library without walls.' Critical pieces of the long-term strategy include streamlining access to sources of STI by using advances in computer networking and graphical user interfaces; creating and disseminating technical information in various electronic media including optical disks, video, and full text; and establishing a Technology Focus Group to maintain a current awareness of emerging technology and to plan for the future.
