Overview of the system. The Audio PC handles sound playback and equalization and controls the overall sequence of an experiment. The interactive visual environment is computed on a second computer (Video PC) and displayed via a video projection system on three screens in the anechoic chamber while being monitored in the control-room. A third computer handles input devices like a trackball. Computers communicate via messages on the network. Flexible extensions on additional computers include a motion tracker to record head and body positions and an eye-tracker (not shown).
