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

6
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

7
Surround Environments (contd)

• 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

8
Surround Environments (contd)

• 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)
