Abstract: A haptic feedback system is disclosed. The system includes a plurality of remote transmitters that are remote from a location of interest on a surface of the system. The system includes a signal generator that generates a signal for each of the remote transmitters. The remote transmitters propagate the signals through a medium of the surface and the signals interfere at the location of interest such that a localized disturbance is generated at the location of interest.

Abstract: An indicator identifying a force intensity of a touch input provided on a touch input surface is received. It is determined that the touch input is associated with an audio volume control. An audio volume is controlled based at least in part on the indicator identifying the force intensity of the touch input.

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 touch input to a propagating medium is identified based on one or more of the following: (1) a determination that a third propagating signal (from a second transmitter to a first receiver) was interfered with while a first propagating signal (from a first transmitter to the first receiver) was not interfered with or (2) a determination that the second propagating signal (from a first transmitter to a second receiver) was interfered with while the fourth propagating signal (from the second transmitter to the second receiver) was not interfered with. In response to the touch input to the propagating medium being identified, a system which includes the first transmitter, the second transmitter, the first receiver, and the second receiver updates.

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.

Abstract: A first transmitter transmits a first propagating signal to a receiver through a first region of a touch input medium corresponding. A second transmitter transmits a second propagating signal to the receiver through a second region where the second region is a subset of the first region. At least the first propagating signal and the second propagating signal are analyzed to identify, based on a determination that the first signal path was disturbed by a touch input while the second signal path was not disturbed by the touch input, the touch input on a part of the first region that is not part of the second region.
