Mandala VR Module hardware.
The Mandala Virtual World System uses a video camera to display a participant's image superimposed over computer-generated graphics. Moving in front of an Ultimatte Blue screen, the Mandala participant watches the interaction on a video monitor. Partic-ipants can interact with 3D graphic objects on the screen while controlling their movements through the environment. This mode of interaction allows completely free, entirely unencumbered interaction with the virtual environment.
