Abstract
Bending wave vibrations propagating in a substrate of a touch input device are sensed. Provision is made for discriminating between sensed vibrations propagating in the substrate indicative of an intended touch and sensed vibrations propagating in the substrate indicative of an unintended touch. In response to the sensed vibrations propagating in the substrate indicative of the intended touch, a wake-up signal is generated. The wake-up signal is communicated to a control system of the touch input device for transitioning the control system from a sleep state to an operational state.
