ABSTRACT
The 1927 French silent film "Napoleon" by director Abel Gance also used a multi-camera widescreen process. One of the most advanced immersive virtual reality (VR) rooms is the StarCAVE, installed at the University of California, San Diego, under the supervision of Tom DeFanti. It utilizes 17 individual screens to create a pentagon-shaped five-walled space, each wall being three screens high, and includes two screens of floor projection. While virtual reality is a relatively new innovation, the state of the art is greatly informed by the many forms of immersive media that have come before. 1991 saw a first attempt at a VR arcade with the Virtuality system and its game "Dactyl Nightmare." Sega's VR-1 motion simulator arcade attraction was introduced in 1994 in SegaWorld amusement arcades. It had the ability to track head movement and also featured stereoscopic 3D polygon graphics.
