Tele-Immersion • Tele-Immersion is the merger of VR worlds and people--3 D phone calls! Tele-Immersion • Tele-Immersion is the merger of VR worlds and people--3 D phone calls! • For each user, Tele-Immersion needs to support: – Viewer-centered perspective – Large angle of view – Stereo – Seeing and talking to distant collaborators University of Illinois at Chicago

Why Represent People ? • Need to know relationship of people to synthetic world Why Represent People ? • Need to know relationship of people to synthetic world • To signal exchange and shared control • To communicate states of collaborators • To recognize people and tell who is talking • And, people want to be “in the picture” University of Illinois at Chicago

Impact: Five Years From Now • Tele-immersion and data mining over high speed networks Impact: Five Years From Now • Tele-immersion and data mining over high speed networks will be routine; audio, video, gesture and haptics will be integrated with latency tolerant techniques • Methods for recording, editing, annotating, replaying, and broadcasting tele-immersive sessions will be perfected; avatars will help convey a true sense of tele-presence University of Illinois at Chicago

International Impact • Tele-immersion is particularly critical for trans-oceanic science and engineering users • International Impact • Tele-immersion is particularly critical for trans-oceanic science and engineering users • Implementation is particularly difficult and challenging as distance increases • Significant participation expected by international researchers via STAR TAP, given support for applications development University of Illinois at Chicago
