Abstract

A high-resolution head-mounted display has been developed from substantially cheaper components than previous systems. Monochrome displays provide 720 by 280 monochrome pixels to each eye in a one-inch-square region positioned approximately one inch from each eye. The display hardware is the Private Eye, manufactured by Reflection Technologies, Inc. The tracking system uses the Polhemus Isotrak, providing (x,y,z, azimuth, elevation and roll) information on the user''s head position and orientation 60 times per second. In combination with a modified Nintendo Power Glove, this system provides a full-functionality virtual reality/simulation system. Using two host 80386 computers, real-time wire frame images can be produced. Other virtual reality systems require roughly $250,000 in hardware, while this one requires only $5,000. Stereo is particularly useful for this system because shading or occlusion cannot be used as depth cues.
