The PAW3003QS-THQT is a high performance and low power CMOS-process optical chip with integrated DSP serving as a non-mechanical motion estimation engine to implement as finger mouse and also known as Optical Finger Navigation (OFN). It is based on new optical navigation technology which measures variation in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement. The movement of △X and △Y are available in the registers accessed via serial port.
