In 1991, EVL produced its first CAVE® (CAVE Automatic Virtual Environment) prototype, a two screen stereo projection system with single-user tracking and navigation. In late 1991 – early 1992, a 4 screen (3 walls/floor) CAVE® system – now including surround-sound – was completed and premiered at the annual SIGGRAPH Conference. This video provides an overview of the CAVE system/technology and a glimpse of some of the applications being developed at the time which cover a broad range of scientific and academic disciplines.
