Abstract
A touch-sensing apparatus includes a signal-receiving module and a control unit. The signal-receiving module includes a mechanical wave-receiving unit and an electromagnetic wave-receiving unit. The mechanical wave-receiving unit is configured to receive a mechanical wave signal actively emitted by a touch object. The electromagnetic wave-receiving unit, adjacent to the mechanical wave-receiving unit, is configured to receive an electromagnetic wave signal actively emitted by the touch object. The control unit is electrically connected to the mechanical wave-receiving unit and the electromagnetic wave-receiving unit, and decides an azimuth angle and a distance of the touch object on a sensing surface with respect to the signal-receiving module according to the electromagnetic wave signal and the mechanical wave signal, and decides a position of the touch object on the sensing surface according to the azimuth angle and the distance. A touch system and a touch-detection method are also provided.
