Virtual reality: fitting adjustments being made to a data suit (blue, center) by Lou Ellen Jones, Asif Emon and Bea Holster at VPL research, Redwood City, California. VPL specializes in virtual or artificial reality systems, the production of computer-generated graphical environments that users may enter. Visual contact with such artificial worlds is provided by a headset equipped with 3-D goggles. A spatial sensor on the headset (to fix the user's position in space) and numerous optical fiber sensors woven into the data suit, relay data back to the computer. The forerunner to the data suit is the data glove, which restricted the user's virtual interaction to hand gestures. Model Released (1990)
