Claim Text:
1. A haptic feedback system including: a plurality of remote transmitters that are remote from a location of interest on a surface of the system, wherein the plurality of remote transmitters is included in the haptic feedback system but is not located at the location of interest; a signal generator that generates a haptic component signal for each of the remote transmitters, wherein the remote transmitters propagate the haptic component signals through a touch screen 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 is substantially localized to the location of interest to generate the localized haptic disturbance that is substantially isolated to the location of interest; and an ultrasonic transmitter that transmits an ultrasonic touch location signal, wherein the ultrasonic touch location signal is allowed to freely propagate in multiple directions through the touch screen medium of the surface of the system, the ultrasonic touch location signal is utilized to detect a location of a touch input and the ultrasonic touch location signal is different from the haptic component signal.
