It contains an LCD projector, and projects an image onto two small mirrors near the bottom and in front of each eyeglass lens. The two mirrors are oriented such that a image appears as if it were a 26'' monitor, located two meters away. Obstructs a portion of the view, but keeps the projected image in the field of view at all times. Envisioned as an ideal tool for surgeons and dentists. CAVE Developed at the University of Illinois at Chicago.
Users wear stereo glasses to correctly view the stereo images.
One user can be head-tracked for more accurate updates of the stereo and perspective projections. Additional controllers such as tracked wands can be used to allow for navigation through the virtual space. CAVE Implementation Projectors are typically 1024x 768 resolution at 96kHz or better. Some implementations have used Systran's Scramnet reflective shared memory to accomplish this. The original CAVE system consisted of two walls and a floor.
