| Title: | TOUCH POSITION DETERMINING DEVICE AND METHOD, AND ELECTRONIC TOUCH-SENSITIVE DEVICE | |||||||||||
| Abstract: | In a device (2) for determining the position (P1(x, y) ) of a touch on a contact surface (1a), a plurality of vibration sensors (4) are configured to detect mechanical vibrations (9) generated by the touch on the contact surface (1a) and to generate corresponding vibration signals, and a processing circuit (6) is connected to the vibration sensors (4) and is configured to determine the touch position (P1 (x, y) ) via a time-of-f light algorithm, based on differences between times of detection (t1, t2, t3) of the mechanical vibrations (9) by the vibration sensors (4). | |||||||||||
