Speaker: Klara Nahrstedt Ralph and Catherine Fisher Professor Department of Computer Science University of Illinois at Urbana-Champaign Title: "Shall we dance …. across thousands of miles? " Date and Location: July 21, 2008 6:30pm Refreshments and Networking 7:00pm Presentation Cisco Building 3, 2F New Frontier Televised Conference Room 225 E. Tasman Dr. San Jose, California 95134 Abstract: Tele-immersive 3D multi-camera, multi-display room environments are the next generation of emerging cyber-physical spaces with many opportunities for joint physical activities, such as dancing across geographically distributed sites. To enable such tele-immersive environments, new challenging research questions must be answered. One important question is how to organize the large amount of visual data, being captured, processed, transmitted and displayed, and their corresponding resources over current COTS computing and networking infrastructures so that “everybody” would be able to use tele-immersive environments for collaborative physical activities. In this talk, I will argue that we need to introduce a concept of a “view” within the tele-immersive spaces and design overlay networking substrate that will link the human, application and physical environment semantics. The “view” specifies sensing information that (a) surrounds the user in the physical space and (b) expresses user’s desires what she wants other people to see. We will present our view-based overlay network framework design with a QoS-enabled management and delivery of tele-immersive visual streams between remote tele-immersive rooms. The current experiments within our testbed, called TEEVE (Tele-immersive Environments for EVErybody), between University of Illinois at Urbana-Champaign and University of California, Berkeley show that we can sustain a strong interactive communication for dance-like applications. I will discuss the successes, supported by the current TEEVE system, as well as point out the various challenges that still remain in these very interesting environments. About the speaker: Klara Nahrstedt is a full-time professor at the University of Illinois at Urbana-Champaign, Computer Science Department. Her research interests are directed towards multimedia middleware systems, quality of service (QoS), QoS routing, QoS-aware resource management in distributed multimedia systems, P2P streaming, tele-immersive environments, trust management in mobile systems, and multimedia security. She is the coauthor of the widely used multimedia books `Multimedia: Computing, Communications and Applications' published by Prentice Hall, and ‘Multimedia Systems’ published by Springer Verlag. She is the recipient of the Early NSF Career Award, the Junior Xerox Award, IEEE Communication Society Leonard Abraham Award for Research Achievements, Ralph and Catherine Fisher Professorship Chair, and IEEE Fellow. She was the editor-in-chief of ACM/Springer Multimedia Systems Journal (2000-2005), she was the general co-chair of ACM Multimedia 2006, the general chair of ACM NOSSDAV 2007, she will be the general chair of IEEE Percom 2009, and she currently serves as the elected chair of ACM Special Interest Group in Multimedia (2007-2009). Klara Nahrstedt received her BA in mathematics from Humboldt University, Berlin, in 1984, and M.S. degree in numerical analysis from the same university in 1985. She was a research scientist in the Institute for Informatik in Berlin until 1990. In 1995, she received her PhD from the University of Pennsylvania in the Department of Computer and Information Science.	Sponsored by:
