Abstract
The invention relates to a pointing device including a touch plane for an object moving thereon to generate a sound, a microphone for converting the sound into a sound wave signal, and a control unit. The control unit receives the sound wave signal and determines a moving direction of the object, so as to generate a direction signal. Accordingly, the moving direction of the object can be determined according to the sound wave signal received by the microphone, such that the volume and the cost of the pointing device of the invention can be reduced.
