Abstract:
A touch pad device and method for determining a position of an input object on the device uses multiple sensing electrodes to produce signals induced by mutual capacitive coupling that are dependent on which conductors of the device are being electrically contacted by the input object. These signals are then processed to determine the position of the input object on the touch pad device.
