METHOD AND APPARATUS FOR PROVIDING INPUT TO A PROCESSOR, AND A SENSOR PAD

摘要

An apparatus for providing input to a processor includes a sensor pad having a surface and a sensor array for sensing pressure at the surface and producing signals corresponding to the pressure at the surface The sensor array having columns and rows of electrodes that are covered with resistive material which fills in the spaces between the electrodes and acts as a linear resistor between the electrodes and measures pressure on the pad surface between the electrodes The sensor array having columns and rows of electrodes that are covered with resistive material which fills in the spaces between the electrodes and acts as a linear resistor between the electrodes and measures pressure on the pad surface between the electrodes There is the step of communicating the signals to the processor in contact with the sensor pad and in communication with the sensor array which couples to the processor
