Abstract:
A touch sensing method adapted for a touch panel is provided. The touch sensing method includes following steps. An average value of touch values generated by a touch object on the touch panel is calculated during a first frame period. An amplitude value of the touch values generated by the touch object on the touch panel is calculated based on the average value during a second frame period. Whether the touch object is a target to be sensed is determined based on the amplitude value. Furthermore, a touch sensing apparatus is also provided.
