VIDEO SYSTEMS mix computer graphics with camera images that approximate what the user would normally see. In this design, light from the surrounding world is captured by a wedge prism and focused on a charge-coupled device that converts the light to digital video signals. The system combines the video with computer graphics and presents the merged images on the liquid-crystal display. Video systems can produce opaque graphics but cannot yet match the resolution and range of the human eye.
