ABSTRACT:
The present invention provides a multiple region vibration-sensing touch sensor that incorporates at least two sets of vibration sensors on a single touch plate, each set of vibration sensors defining distinct touch regions. The vibration sensors detect vibrations indicative of a touch to the touch plate, and are configured to communicate signals representing the detected vibrations to controller electronics for determining information related to the touch input. Touches within each touch region can be distinguished.
