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.

Abstract: In a multiple-projector concave-screen display system, spacial alignment of images on the screen, is enabled by designating calibration points with retro-reflective dots and illumination markers. The manufacture of the screen involves locating calibration points and depositing the dots with a tool utilizing a rotary mechanism for loading and applying the dots from solenoid actuated pod units. Areas for retro-reflective dots, versus illumination markers, are defined on the basis of reflectance angles between vectors to the screen from a projector and from the screen to a viewer.

Abstract: Disclosed is a mechanical translation linkage and lamp support apparatus for maintaining the projection light source inside a gimballed transparency displaced from the geometric center of the transparency and in a fixed spatial relation with the center of the transparency as the transparency rotates about any of its three mutually perpendicular axes. The translation apparatus employs only a mechanical linkage to ground and reacts to rotation of the support gimbal about either the X or Y axis to maintain the projection light source at the required position regardless of the attitude of the gimbal.
