Abstract
A gesture sensing device includes a multiple segmented photo sensor and a control circuit for processing sensed voltages output from the sensor. The control circuit processes the sensed voltage signals to determine target motion relative to the segmented photo sensor. The control circuit includes an algorithm configured to calculate one of more differential analog signals using the sensed voltage signals output from the segmented photo sensors. A vector is determined according to the calculated differential analog signals, the vector is used to determine a direction and/or velocity of the target motion.
