Abstract
The human-machine interface is generalized beyond traditional control devices to permit physical participation with graphic images. The VIDEOPLACE System combines a participant’s live video image with a computer graphic world. It also coordinates the behavior of graphic objects and creatures so that they appear to react to the movements of the participant’s image in real-time. A prototype system has been implemented and a number of experiments with aesthetic and practical implications have been conducted.
