Abstract
A touch device includes a plurality of sensors, a storage module and a processing module. The sensors are placed on a substrate for detecting acoustic waves and generating electrical signals. The storage module stores a plurality of templates of delay measurement for a plurality of locations on the substrate. The processing module is coupled to the sensors and to the storage module for calculating a received delay measurement and comparing the received delay measurement to the plurality of templates of delay measurement to estimate touch location. A detection method for the touch device is also provided.
