Scientists In Wonderland

(1993) Traditional computer graphics has typically required that scientists look through a restricted window (the computer screen), to view images that depict their research data. Virtual Reality (VR) on the other hand, offers scientists the means to leap through that window and physically engage their experimental environment.

The idea of stepping inside the computer with a natural interface for interaction, to experience virtual environments was first proposed by Ivan Sutherland with his Ultimate Display[sutherland65]. Since then, devices and systems have been built to better immerse humans in computer-generated worlds. These devices typically fall into three categories: (1) viewing devices, (2) tracking devices and (3) interactive devices. Head-mounted displays (HMD) like the VPL eyephones [teitel90] and the Flying Helmet have become the most popularized VR viewing devices. Others include the BOOM [mcdowall] and the CAVE [cruz92]. Tracking devices like the Polhemus Isotrack and Ascension Technology's Flock of Birds allows the computer to determine the location and orientation of a person in the virtual space. Finally, devices that allow the user to interact with and perceive virtual worlds include the popular VPL Data Glove.

This video explains how the CAVE® Virtual Reality Theater functions, and shows all the hardware outlined above. Additionally, the video shows several early VR graduate student projects.
