The Virtual Reality CAVE

 

A Virtual Reality CAVE is a virtual reality environment that consists of a number of walls that are placed in the form of a cube around the user(s). Three-dimensional images are projected on the walls using 2 projectors per side. CAVE is an acronym that stands for CAVE Automated Virtual Environment. A CAVE accommodates a small group of people. The number of walls can range from 4 (the most common form) to 6, wherein the users are fully enclosed. The users wear special glasses to truly see three-dimensional (stereoscopic) images. Users can exert influence on the 3D world by means of a motion tracking system. In September 2008, a virtual reality CAVE was placed by ProSystems at Fontys University of Applied Science, School of ICT.
