CAVE technology,that means four video projectors show moving stereo pictures, using one floor projection and three wall projections, in a cubic space. These join together to form a continual three-dimensional impression for the visitors. This makes the virtual representation of individual objects or even of whole landscapes possible. Acoustically, a spatial impression is made by the spatial representation of sound scenarios as well as by moving sounds produced by eight loudspeakers mounted in different places around the cube. The floor is designed as a vibrating element. By linking several sensory impressions, the illusion of immersion in the virtual scene is strengthened. This is what has made CAVE installations prototypes of immersive environments.
