Abstract
At a receiver associated with a transmitter-receiver pair, a propagating signal transmitted by a transmitter associated with the pair is received. A detected disturbance to a signal property of the propagating signal is analyzed with respect to reference data associated with the pair to detect whether a touch input has been provided. If the detected disturbance meets a criteria then the reference data associated with the pair is updated using the received propagating signal.
