An optical mouse is an advanced computer pointing device that uses a light-emitting diode (LED), an
optical sensor, and digital signal processing (DSP) in place of the traditional mouse ball and
electromechanical transducer. Movement is detected by sensing changes in reflected light, rather
than by interpreting the motion of a rolling sphere. The optical mouse takes microscopic snapshots of the working surface at a rate of more than 1,000... | |||
