    Spatial input/display correspondence in a stereoscopic computer graphic work station



    An interactive stereoscopic computer graphic workspace is described. A conventional frame store is used for three-dimensional display, with left/right eye views interlaced in video and viewed through PLZT shutter glasses. The video monitor is seen reflected from a half silvered mirror which projects the graphics into a workspace, into which one can reach and manipulate the image directly with a “magic wand”. The wand uses a magnetic six degree-of-freedom digitizer. In an alternative configuration, a graphics tablet was placed within the workspace for input intensive tasks.
