Abstract
(EN)

Disclosed is a touch input device that determines touch position by sensing vibrations propagating in a touch plate that are indicative of a touch to the touch plate. Vibration sensing devices such as piezoelectric sensors are used to sense the vibrations. Selecting the size, shape, placement position and orientation of the sensors on the touch plate can enhance sensitivity of the sensors to vibration and yield symmetric response with respect to the direction of vibration propagation. Also disclosed is a method of making a vibration sensing touch input device.
