Abstract: A propagating signal transmitted through a propagating medium is received where a detected disturbance to a signal property of the propagating signal is analyzed to detect whether a touch input has been provided. It is determined whether the detected disturbance matches a signature and in the event it is determined that the detected disturbance matches the signature, it is determined that the detected disturbance does not correspond to the touch input.

Abstract: A sensor includes a plurality of piezoresistive elements. A physical disturbance sensor may be formed by configuring the piezoresistive elements in a resistive bridge configuration. A signal transmitter is electrically connected to the physical disturbance sensor and configured to send an encoded signal to the piezoresistive elements of the resistive bridge configuration. A signal receiver is electrically connected to the piezoresistive elements and configured to receive a signal from the physical disturbance sensor. The received signal from the physical disturbance sensor is correlated with the sent encoded signal in determining a measure of physical disturbance. A system for detecting a location of a touch input on a surface of a propagating medium includes a piezoresistive sensor coupled to the propagating medium. The piezoresistive sensor is configured to at least detect a force, pressure, or applied strain of the touch input on the propagating medium.

Abstract: Determining a touch contact location is disclosed. A signal that has been disturbed by a touch input on a surface is received. The received signal is transformed to determine a spatial domain signal. The spatial domain signal is compared with an expected signal associated with a potential location of a source of a disturbance caused by the touch input. The touch contact location of the touch input is determined based at least in part on the comparison.
