Zusammenfassung:	A touch sensitive device including a front panel having a touch surface and a back surface opposite the touch surface. The touch sensitive device further includes one or more vibration transducers mounted to the back surface, and a controller electronically connected to the vibration transducer. The controller receives, from the vibration transducer, a vibration signal, extracts feature information corresponding to predetermined features from the vibration signal, determines, based on the feature information, that a touch occurred within a predefined area of the touch surface, and outputs a signal indicating that the touch occurred within the predefined area of the touch surface.
