Virtual reality: data suit design. John Bumgarner at VPL Research Inc., Redwood City, California, discussing technical points relating to the design of the blue data suit being worn by Lou Ellen Jones on left. VPL produces virtual reality systems - computer generated graphical environments that a user may enter & interact with. Visual contact 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)
