CAVE (Cave Automatic Virtual Environment)

	Schematic of an idealized Cave VR system. Tiled rear projection stereo images appear on up to six faces of the room in which the operator works. In practice, most Caves have three to four faces with projections. (Image from: Cruz-Neira, Sandin, DeFanti, Kenyon and Hart, 1992).

The CAVE (Cave Automatic Virtual Environment) was developed at the University of Illinois at Chicago and provides the illusion of immersion by projecting stereo images on the walls and floor of a room-sized cube. Several persons wearing lightweight stereo glasses can enter and walk freely inside the CAVE. A head tracking system continuously adjust the stereo projection to the current position of the leading viewer.
