Interactive Three-Dimensional Computer Space
C. Schmandt · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1983
Work is described which merges 3-D input and display technologies to implement a real time interactive computer graphics environment, generating a stereoscopic image that one creates by reaching directly into it. The display is an ordinary video monitor, reflected off a half-slivered mirror, and viewed through PLZT opto-electrical shutter glasses. For input, an electromagnetic six degree-of-freedom digitizer is mounted in a small wooden "magic wand", with a pushbutton mounted in the handle.
