Abstract

A simulator system for use in providing an event simulation to an occupant includes a motion base moveable only along three mutually orthogonal displacement axes by means of displaceable actuators. An audio-visual display mechanism is included for providing a sequence of audio and visual images to the occupant. A motion base controller generates actuator drive signals. A system controller provides the command signals to the motion base controller in synchronization with the presentation of the audio-visual images. The projected visual images including 'foreground' and 'background' portions. The system controller generates the motion base command signals such that the displacement of the motion base is synchronized to the onset of movement of the foreground image and the foreground image is constrained to move, relative to the occupant, only along the same three orthogonal axes as the motion base.
