Filed:

Jul 28, 1994

Appl. No.:

8/282925

Joe L. Walker - Salt Lake City UT
Paul C. Lyon - Sandy UT
Richard B. Linton - Salt Lake City UT

Assignee:

Evans & Sutherland Computer Corp. - Salt Lake City UT

International Classification:

G09B 924
G09B 934

US Classification:

434 43

Abstract:

The present invention is directed to a simulation system for simulating virtual reality experiences such as for the sport of hang gliding or the like. The simulation system has a stereoscopic and collimated virtual image display, for providing pupil forming simulated images to a rider at a fixed point of reference relative to the stereoscopic display. In the disclosed embodiment, the simulation system comprises a mechanical support structure for suspending the rider in a harness so as to allow freedom of movement. The rider is suspended to face a visual display over a movable control bar coupled to the mechanical support structure. By maneuvering the control bar, riders may view the results of their actions as by a simulated display. The visual display is coupled to the control bar to receive electrical signals indicative of the movements initiated by the riders as they maneuver through a programmed environment. The visual display provides stereoscopic "pupil forming" images of positional states of the hang glider to the riders at a fixed point of reference relative to the visual display.
