TOUCH STICK CONTROLLER USING CAPACITANCE TOUCHPAD CIRCUITRY AS A MEASUREMENT SYSTEM

摘要

Capacitance-sensitive touchpad circuitry used for detecting and tracking an object on the surface of a touchpad now receives as inputs to the circuitry the voltage divider signals from each axis of a strain gauge used as a touch stick input device, wherein the touchpad circuitry is far less sensitive to noise, and wherein touch stick control circuitry can be eliminated through the use of existing touchpad circuitry.
