MIXED REALITY :THE CAVE

teaser.jpg

The CAVE is a multi-person, room-sized, high-resolution, 3D video and audio environment. Graphics are rear projected in stereo onto three walls and the floor, and viewed with stereo glasses.As a viewer wearing a location sensor moves within its display boundaries, the correct perspective and stereo projections of the environment are updated, and the image moves with and surrounds the viewer. The other viewers in the CAVE are like passengers in a bus, along for the ride! “CAVE,” the name selected for the virtual reality theater, is both a recursive acronym (Cave Automatic Virtual Environment) and a reference to “The Simile of the Cave” found in Platos “Republic,” in which the philosopher explores the ideas of perception, reality, and illusion. Plato used the analogy of a person facing the back of a cave alive with shadows that are his/her only basis for ideas of what real objects are.
