Computer interactive motion simulator

Abstract

A motion simulator uses an existing personal computer and off the shelf software to physically simulate and control the motions of a computer generated vehicle. The motion simulator is manually powered by the user and includes a control stick connected to an input to the computer whereby movement of the control stick is translated into movement of the computer generated vehicle. A rigid control arm connects the control stick to a base unit and to a cockpit frame to move the cockpit frame relative to the base unit as the control stick is moved. The control stick also contains buttons which provide additional inputs to the computer generated vehicle. Foot operated pedals are also connected to the computer program and to the cockpit to move the cockpit in conjunction with movement of a computer generated vehicle. A throttle lever unit is also connected to the computer to control the computer generated vehicle. The center of gravity of the cockpit is located below the pitch and roll axis so the cockpit tends to return to an initial position. Gravity assists the cockpit and control stick in resisting movement whereby realism is added to the simulation. A trim adjusting wheel moves the seat unit fore and aft to adjust center of gravity of the cockpit frame to position the cockpit frame in a pitch up or pitch down position. A releasable parking mechanism securing the cockpit frame to the base unit immobilizes the simulator for safe boarding. A speaker bracket on the seat unit provides a place to mount stereo speakers for added realism.
