Abstract
A pressure-sensitive control device for a simulated vehicle in a video game or simulator. In the preferred embodiment a brake pedal control device is implemented having a strain gauge which senses the strain in the material of the brake pedal. This strain is amplified by a differential amplifier having a self-adjusting input circuit with a long time constant which causes any variations in the input voltage not due to changing strain on the brake pedal to be applied to both inputs of a differential amplifier in common mode, thereby cancelling the effect thereof. Only voltage differences resulting from variations in the strain on the brake pedal are amplified by the differential amplifier and output for use by the video game or simulator.
