Abstract: A dynamic distortion correction apparatus 100 for use in an image projector 120. The invention includes a computer image generator 144 for generating a video image signal. A control circuit 102 processes the video image signal and regulates the clocking rate of a time-delayed video output signal. A modulator 104 is included for converting the video output signal to an optical image signal having a plurality of television raster lines. An optical device 148 is incorporated which orients each of the plurality of raster lines to compensate for distortion in the optical image signal at any viewing angle. A gimballed mirror 126 and a color projection optic device 178 are included to control the projection of the optical image signal onto a surface 110 to provide a display image 106. In a second embodiment, the optical device 148 is replaced by a correcting feature of the computer image generator which causes each of the raster lines to be parallel to every other raster line.

Abstract: The system includes a computer (20), a detector (40) for detecting and tracking head orientation and head movement of an individual, a pair of tactile gloves (42, 44) which are donned by the individual (51) for detecting and transmitting to the computer (20) as input data orientation and movements of the hands of the individual inserted in the tactile gloves (42, 44), a stereoscopic, head-mounted display (31), a subsystem for enabling the computer to generate a stereoscopic image of the training environment, a subsystem for causing the stereoscopic image of the training environment to be displayed and changed by the computer relative to input data received by the computer relating to the head orientation and head movement of the individual, relative to input data received by the computer relating to orientation and movement of the hands of the individual inserted in the tactile gloves, and relative to input data reflecting realistic changes in the training environment that would be perceived by the individual

Abstract: A system (10) for simulating an operating environment, such as aircraft cockpit for use in training. The system (10) includes a video storage device (46) for storing and transmitting an image of the operating environment. The video storage device (46) is coupled to a video monitor (58) for displaying the stored image. A graphics generator (54) generates an overlay image simulating the appearance of displays and manipulable controls in the operating environment in a plurality of its manipulative states. The graphics overlays may be manipulated by means of a touch sensitive screen (64) to simulate the operation of the manipulable controls. The system also includes an interactive system (12) for authoring and editing the overlays as well as the simulation process.
