What is Tele-Immersion Networked Virtual Reality
High Speed Network: Internet 2 Virtual Reality
• computer generated, interactive, three-dimensional environment in which a person is immersed
About Tele-Immersion
• Will transform the way people collaborate at a distance • computers recognize the presence and
movements of individuals and objects• track those individuals and images• permit them to be projected in realistic,
multiple, geographically distributed immersive environments on stereo-immersive surfaces.
Virtual Reality High performance computer
graphics system Interactive Immersive
Fully & Partially Immersive
Surround Environments CAVE (Fully immersive)
• 3 rear-projected screens for walls and a reflective projection for the floor
• Stereographic LCD shutter glasses• High-resolution, high bandwidth• Computer controlled audio, support
multiple speakers• Tracking system for users’ head
movements
Surround Environments (cont’d) Responsive Workbench
Tabletop environment Stereo graphics via projector-and-mirror
system Shuttered glasses Tracking system for head, as well as
gloves and stylus to interact
Surround Environments (cont’d) Both CAVE and Responsive
Workbench are quite expensive $1,000,000 for CAVE
Our goal – build low cost VE $10,000 or less Horizontal Virtual Table (had before) Vertical Virtual Table (soon)
