Integrated Media Technologies for Satellite Decision Support Systems

Sutton, S. A., Yu, C. S. 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / Within the Aerospace industry, the operational community is facing staff reductions, reduced skill levels, and greater complexity of space assets and space missions. This combination requires that techniques be developed that more efficiently interface a human operator with a complex computer system. Operational support of complex space systems will be greatly facilitated by better presentation of information. The presentation and distribution of complex data must evolve towards formats that are easily and naturally embraced by our sensory systems. Some of the information technologies/techniques that facilitate the presentation of complex dynamic graphical data fall into a category called integrated media. The cost of implementing integrated media (IM) architectures has decreased substantially within in the past five years. While implementation costs continue to recede, the quality and value of information that can be presented using IM technologies continues to improve. Today's IM architect can select a variety of components including digital interactive video, 3D Navigable Worlds, Multimedia Authoring Systems, standardized compressors for IM data, low cost high volume storage systems, and operating system extensions for temporal data management. Together, these components form a solid foundation for the development of a variety of compelling IM architectures. Existing satellite support and mission data processing architectures typically present tabular data for assessment. Some "advanced" systems include 2D graphical projections of the data. System experts are generally trained to correlate relationships between tabular data items. The training required to "learn" these complex relationships is tedious and time consuming. This complexity impedes productivity and as space systems increase in sophistication, these techniques for data assessment are quickly becoming antiquated. The development of a prototype decision support system explores the utility of an integrated media documentation system as part of a full-featured decision support architecture for satellite operations.

Recursos educativos digitales Procesos de mediación y mediatización en la comunicación pedagógica

Sulmont Haak, Lea 14 April 2015 (has links)
The knowledge processes have been experiencing radical transformations due to the latest information and communication technologies incorporation. In this stage, it is important to pay special attention to the way contents and resources productions evolves and its integration in the learning-education process. At the moment, production dynamics of the educative resources are registered by the concept of learning objects, the logical of reusability and the use of standards on the digital contents processes. These concepts suggest a new philosophy, a new way to produce contents, but above all, a new way to distribute and share them. Along to this tendency, it is necessary to look in depth aspects of pedagogical design and cognitive considerations about contents and ways in which digital resources are used as a strategy that will lead to an effective use of these elements in the learning education process. From pedagogical communication perspective, the task establishes a reflection on the interchange processes produced within the pedagogical triangle and with the contribution of technological tools and digital educative resources. The bases that support this reflection turn around the forms of mediation of the pedagogical relation and to insert content into the media through digital educative resources that use multimedia language. / La gestión del conocimiento viene experimentando transformaciones radicales con la incorporación de las tecnologías de la información y de la comunicación (TICs). En este proceso, es importante prestar atención a la evolución de las formas de producción de contenidos y recursos, y su respectiva integración en el proceso de enseñanza-aprendizaje. El trabajo plantea una reflexión sobre los procesos de intercambio producidos dentro del triángulo pedagógico con el aporte de herramientas tecnológicas y recursos educativos digitales. Se toman en cuenta aspectos de diseño pedagógico y consideraciones cognitivas sobre los contenidos y medios usados, como una estrategia para analizar la evolución de los roles de estudiantes y docentes en el proceso de enseñanza-aprendizaje. Los cuestionamientos giran en torno de las formas de mediación de la relación pedagógica y de mediatización del contenido a través de recursos educativos digitales que utilizan el lenguaje multimedia.

Dinner For One

Ball, Cheryl E 01 January 2000 (has links)
Dinner For One, a hypermedia poetry thesis, explores the themes of aloneness, sexuality, independence, and journeys of discovery and distance. The Chinese zodiac stamps used as navigational elements in Dinner for One and the prose poems written as postcards to oneself an others reinforce the notion of travel. The fortunes from Chinese cookies give prophecies and horoscopes, reminding us of our fate, which is beyond our conrol. Dinner For One means to question, through poetry and interactive, hypertextual reading techniques, how much faith and trust we should hold in influences outside of our lives. The poems in this thesis are meant to be an examination of what we tell ourselves and, sometimes, make ourselves believe.This multimedia, interactive presentation is written with Macromedia 2000.

The Immersive Media Library @ VCU

Rosenthal-Mix, Michael 01 January 2015 (has links)
Answering the call issued by John Underkoffler in 2010 about the future of UI, I have imagined the Immersive Media Library (IML) as an annex of the main VCU library, offering a concentration of visually immersive spaces to compliment the space the university is already building in the renovated Cabell Library. The design is new in that the emphasis is placed on the collaboration between librarians and visitors in creating new work. Focusing on the interpersonal might be unexpected from program with such an emphasis on new technology - but I see it as vital part of the new computing paradigm.

The pathway active learning environment: an interactive web-based tool for physics education

Nakamura, Christopher Matthew January 1900 (has links)
Doctor of Philosophy / Department of Curriculum and Instruction / Dean A. Zollman / The work described here represents an effort to design, construct, and test an interactive online multimedia learning environment that can provide physics instruction to students in their homes. The system was designed with one-on-one human tutoring in mind as the mode of instruction. The system uses an original combination of a video-based tutor that incorporates natural language processing video-centered lessons and additional illustrative multimedia. Our Synthetic Interview (SI) tutor provides pre-recorded video answers from expert physics instructors in response to students’ typed natural language questions. Our lessons cover Newton’s laws and provide a context for the tutoring interaction to occur, connect physics ideas to real-world behavior of mechanical systems, and allow for quantitative testing of physics. Additional multimedia can be used to supplement the SI tutors’ explanations and illustrate the physics of interest. The system is targeted at students of algebra-based and concept-based physics at the college and high school level. The system logs queries to the SI tutor, responses to lesson questions and several other interactions with the system, tagging those interactions with a username and timestamp. We have provided several groups of students with access to our system under several different conditions ranging from the controlled conditions of our interview facility to the naturalistic conditions of use at home. In total nearly two-hundred students have accessed the system. To gain insight into the ways students might use the system and understand the utility of its various components we analyzed qualitative interview data collected with 22 algebra-based physics students who worked with our system in our interview facility. We also performed a descriptive analysis of data from the system’s log of user interactions. Finally we explored the use of machine learning to explore the possibility of using automated assessment to augment the interactive capabilities of the system as well as to identify productive and unproductive use patterns. This work establishes a proof-of-concept level demonstration of the feasibility of deploying this type of system. The impact of this work and the possibility of future research efforts are discussed in the context of Internet technologies that are changing rapidly.

Automatic Affective Video Indexing: Identification of Slapstick Comedy Using Low-level Video Characteristics

French, Jean Helen 01 January 2011 (has links)
Recent advances in multimedia technologies have helped create extensive digital video repositories. Users need to be able to search these large video repositories in order to find videos that have preferred content. In order to meet the needs of users, videos in these repositories need to be indexed. Manual indexing is not an appropriate method due to the time and effort involved. Instead, videos need to be accurately indexed by utilizing computer-based methods. Automatic video indexing techniques use computer technology to analyze low-level video features to identify the content that exists in videos. The type of indexing used in this study is automatic affective video indexing, which is an attempt to index videos by automatically detecting content that elicits an emotional response from individuals. The specific affect-related content of interest in this proposed study is slapstick comedy, a technique that is used in videos with humor. The methodology of this study analyzed the audio stream as well as the motion of targeted objects in videos. The relationship between the changes in the two low-level features was used to identify if slapstick comedy was present in the video and where the instance of slapstick could be found. There were three research questions presented in the study which were associated with the two goals. Research Question 1 determined whether or not the targeted content could be identified using low-level features. Research Question 2 measured the relationship between the experimental results and the ground truth in terms of identifying the location of the targeted content in video. Research Question 3 determined whether one type of low-level feature was more strongly associated with the target content than the other. Goal 1 was to utilize sound and motion to predict the existence of slapstick comedy in videos. Goal 2 was to utilize sound and motion to predict the location of slapstick comedy in videos. The results of the study showed that Goals 1 and 2 were partially met, prompting an investigation into methodology improvements as part of this research. The results also showed that motion was more strongly related to the target content than sound.

Development of a Media Driven Online Assessment System: Improving Quality, Frequency, and Deployment of Grades and Feedback in Higher Education

Juarez, James Jay 01 January 2013 (has links)
Information communication technologies (ICT) in education is an expanding field, and within this field there is a need for development of effective systems for faculty and learners to communicate feedback and assess performance. The increasing migration of many academic disciplines and courses to an online format has prompted an increased need for the development of evidence-based tools and techniques that can be made available to educational institutions in order to connect and communicate with the learner. Many faculty and students have been faced with a less than optimal transition to the online environments and for these faculty and students, educational performance can be hindered. Guided by a developmental research methodology (DRM), the researcher examined the need for a novel communication and assessment system, the elements required for such a system to succeed, the building of such a system, and finally the testing of the initial effectiveness of the system. The developed system, known as an Online Assessment System (OAS) or Gradeswift (prototype name), incorporated criterion based assessment utility with multi-modal (text, voice, and video) functionality to create an asynchronous means for communicating effectively through online information storage and delivery. It was shown that the OAS had a significant impact on the educational landscape by providing better communication and performance assessment. Additionally, the OAS had been designed to increase the efficiency of the process of assessment, thus assisting faculty with workload and time required to assess student assignments. Last, students have the added benefit of receiving personalized feedback from instructors, enhancing the experience and perceived usefulness of online assessment.

Ubiquitous collaborative multimedia capture of live experiences toward authoring extensible interactive multimedia documents / Captura multimídia colaborativa ubíqua de experiências ao vivo para autoria de documentos multimídia interativos extensíveis

Uscamayta, Andrey Omar Mozo 27 April 2017 (has links)
The growing importance of multimedia content generated by ordinary users demands research for models, methods, technologies and systems that support multimedia production. Despite recent results allowing the collaborative capture of video via mobile devices, there is gap in supporting the collaborative capture of multiple media. In this dissertation we propose that ubiquitous collaborative multimedia production can be carried out by users who capture and annotate multiple media using the CMoViA mobile application. CMoViA also allows export the user-generated content to the CI+WaC, which allows them to edit the user-generated content in the form of interactive and extensible multimedia documents. The proposal demanded extending recent work reported in the literature, namely the I+WaC-IE (Interactors+WaC-Interaction Events) model, the I+WaC-Editor tool and MoViA tool. Hence, CMoViA follows the proposed CI+WaC-IE model. We discuss results from a case study, carried out in the educational domain, in which students collaboratively capture a lecture. / A crescente importância de conteúdo multimídia gerado por usuários amadores exige pesquisas por modelos, métodos, tecnologias e sistemas que apoiem a produção multimídia. Apesar dos recentes resultados que permitem captura colaborativa em vídeo utilizando dispositivos móveis, existe uma lacuna no apoio à captura colaborativa de múltiplas mídias. O trabalho apresentado nesta dissertação propõe que a produção multimídia colaborativa ubíqua possa ser alcançada por usuários que realizem a captura de múltiplas mídias e de anotações utilizando o aplicativo móvel CMoViA. CMoViA também permite que o conteúdo gerado por esses usuários seja exportado para a plataforma CI+WaC, a qual permite editar e anotar documentos multimídia interativos. Essa proposta requer a extensão de trabalho recentes reportados na literatura: o modelo I+WaC-IE (Interactors+WaC-Interaction Events), a ferramenta I+WaC-Editor e a ferramenta MoViA. Assim, a aplicação CMoViA segue o modelo CI+WaC-IE proposto neste trabalho como extensão do modelo I+WaC-IE. A proposta foi avaliada por meio de estudo de caso realizado no domínio educacional, no qual estudantes capturam colaborativamente uma palestra.
