CAVERN Networks not only facilitate but seem to mandate partnerships • CAVE Research Network (CAVERN) • CAVE Research Network User’s Society (CAVERNUS) University of Illinois at Chicago
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 • 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
Two Representations of People • Video images • Synthetic models (avatars) University of Illinois at Chicago
Tele-Immersion and CAVERNsoft • Tele-Immersion requires expertise in graphics, VR, audio/video compression, networking, databases • Rapidly build new teleimmersive applications • Retro-fit old applications • CAVERNsoft enables applications! University of Illinois at Chicago

Requirements for Tele-Immersion • Collaborative interaction and manipulation • Communication: audio, video & avatars (virtual participants) • Synchronous and asynchronous work • Network and database quality of service • Multiple heterogeneous data streams University of Illinois at Chicago
More Requirements for Tele-Immersion • • • Flexible connectivity High level modules for developers Performance monitoring Recordability Trans-oceanic capability Cultural sensitivity (e. g. , avatar gesture translators) University of Illinois at Chicago

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 • 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
