Title: "Multimedia: from Information Source to Components of Transformational Games"  

Abstract:


Mike Christel will discuss his journey with multimedia research over the past six years, taking him from Carnegie Mellon University's Computer Science Department into the Entertainment Technology Center (ETC).  The story begins with the use of speech recognition, image processing, and language technologies to automatically process large video corpora.  Such processing facilitates more efficient retrieval.  As demonstrated by top scores in the international TRECVID benchmarking forum, Christel's CMU Informedia research group has experienced success in finding relevant video shots quickly from large masses of material.  The emphasis is on leveraging the intelligence of a human user in the interactive retrieval loop, with lessons shared in visual analytics papers.

That work drew the attention of oral historians, who amassed large quantities of video stories that were not easily accessible.  The value of synchronized metadata to open up these collections for the web audience will be detailed with examples.  This work illustrates the power of multimedia processing to help organize and present cultural repositories.  As the user community appreciated the layers of meaning within these often riveting stories, Christel was drawn to the power of multimedia elements in entertainment technologies, including games.

Transformational games are designed to change the player in some way, such as improving health habits, changing attitudes, or providing education.  The ETC provides multidisciplinary teams of graduate students with skills in visual arts, design, sound, programming, and production the opportunity to create such games in the course of a semester-long project.  Christel will briefly overview this development process, and then demonstrate some of the ETC-produced games, illustrating the role of multimedia elements within them and the promise of the work to positively affect the game player.


Speaker Bio

Dr. Mike Christel received his Ph.D. from Georgia Tech in 1991, with a thesis examining digital video interfaces for training software engineers about code inspections. He graduated "summa cum laude" with a B.Sc in Mathematics and Computer Science from Canisius College in 1983.  He joined the faculty at the Entertainment Technology Center (ETC) from Carnegie Mellon University in September 2008, moving from the Computer Science Department where he has been since 1997 working at the intersection of speech recognition, image processing, and multimedia interface development and evaluation. From 1987 to 1997 he worked at the Software Engineering Institute at Carnegie Mellon University investigating multimedia management of the requirements elicitation process, and multimedia for interactive software engineering educational experiences.

Dr. Mike Christel is a founding member of the Informedia research team at Carnegie Mellon University designing, deploying, and evaluating video analysis and retrieval systems for use in education, health care, and understanding of human activity. His research interests focus on the convergence of multimedia processing, information visualization, and digital library research. He has worked with digital video since its inception in 1987 and received his PhD from Georgia Tech in 1991. Whereas his Informedia work has focused on multimedia for information and communication, the ETC offers broad opportunities to explore multimedia for engagement and edutainment.

Title: "Extracting Context from the Web to Help Visually Impaired Pedestrians Develop Cognitive Maps of Their Environments"  

Abstract:

A rich cognitive map of an environment can enhance an individual’s experience within the space. However, acquiring knowledge about an environment can be challenging for people with visual impairments. They often need support by sighted people to understand what is in the environment, associate meaning to these objects and places, identify where different objects and places are positioned, and their spatial relationship with each other. In this talk, I will present how the power of the Web can be leveraged in ubiquitous computing tools to help a user learn an environment. I will discuss what information is required by visually impaired pedestrians, when and where to provide this information, and also how to collect and present it. Finally, I will describe how this work can be extended to benefit the general population.

Khai N. Truong is an associate professor in the Department of Software and Information Systems at the University of North Carolina, Charlotte. His research lies at the intersection of Human-Computer Interaction (HCI) and Ubiquitous Computing (UbiComp), specifically examining the mutual impact of usability and technical constraints on the design of applications and interaction techniques for novel, off-the-desktop computing systems that may be commonplace in 5-10 years. He received his PhD in computer science from the Georgia Institute of Technology.

Title: Designing and Developing Interactive Multimedia Systems   

Abstract:

This talk presents the design and development process of interactive multimedia and multimodal systems used in diverse environments. The technologies, including new sensors, interaction surfaces and semantic information processing techniques will be described in the context where they were used. The systems result from collaborative projects in several fields, ranging from cultural heritage to contemporary art and dance. The dialogue with stakeholders from different areas and the impact on the resulting outcomes will be discussed, along with the process of setting up, specifying and developing interdisciplinary projects and the methodologies that are used. Recent work on motion annotation to help choreographic work, image analysis of paintings and digital art projects (e.g., TimeMachine) will be described. The academic and research environment and programs in which this work is done will also be presented.

Title: Collaborative Authoring Requires Advanced Change Management  

Abstract:

Collaborative document authoring is a pervasive activity of modern life. It extends far beyond simple joint authorship to many forms of shared document work, including laws, patient charts, and the editing process. Software engineering is also a form of collaborative authoring, and in general, the software engineers have the best tools for managing collaborative changes, such as version control and build systems. It is the thesis of this talk that collaborating authors of natural language documents need the same kinds of tools that software engineers take for granted. In fact, because of important domain differences, people collaborating on a natural language documents need better tools than software engineers. The document engineering research community has been working on this problem domain for a considerable time, particularly in the area of version control of XML documents, which is the primary representation for modern office documents. Key research results have included a variety of schemes for merging and patching XML document versions, advances in formalizing document deltas, a scheme for controlling author access to the various sections of a document, and demonstrations that authors can edit a document simultaneously over the Internet without locking mechanisms. I will argue that document systems must adopt the full range of version management tools used by software engineer, including full branch-and-merge versioning, but then must extend those tools and simplify their use. We need approaches to sharing documents and merging their changes that are highly automated, that recognize the difference between formatting and content, that permit fine-grained access control, and that help users understand the provenance of changes so that responsibility is correctly assigned. I will show how my laboratory's work on Version-Aware Documents is addressing these issues and describe a longer term vision requiring further research. I will also suggest how the same techniques might impact other domains including medical informatics, eGovernment, and document analysis.
