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.
Claims20
A method, comprising:
- receiving an identifier associated with a location on a surface where a localized haptic disturbance is desired;
- using the identifier to obtain one or more signal configurations to be used to provide the localized haptic disturbance;
- determining one or more calibration factors;
- generating a corresponding haptic component signal for each of a plurality of transmitters including by using location based signal parameters adjusted based on the one or more calibration factors, wherein the plurality of transmitters propagate the haptic component signals through a touch medium of the surface and the haptic component signals interfere at the location of interest such that a localized haptic disturbance is generated at the location of interest and the localized haptic disturbance is generated by an interference of the haptic component signals at the location of interest without a use of a motor and the interference of the haptic component signals that generated the localized haptic disturbance takes place locally at the location of interest to generate the localized haptic disturbance at the location of interest;
- and
- receiving a version of a touch detection signal that has been propagated through the touch medium and disturbed by a touch input on the surface, wherein the received version of the touch detection signal is processed determine a location of the touch input on the surface.
