Abstract
The present invention relates to an apparatus for identifying motions of an object, which is used for detecting motions of at least an object. A sensing plate senses the object and produces at least a sensing signal. A processing circuit is coupled to the sensing plate. It gives at least a moving speed along at least one axis, at least a variation in the sensed value between the object and the sensing plate, or at least a variation in the contact area according to the sensing signal. Then it produces a corresponding control signal according to the moving speed, the variation in the sensed value, or the variation in the contact area. Thereby, the present invention further produces a corresponding control signal by means of the variations in the sensed value. Hence, the control signal can be produced without touching the touch panel and thus increasing the lifetime of the touch panel.
