1. A processing system having a haptic feedback system, comprising:

  • a plurality of actuators configured to provide tactile feedback associated with an input surface, each actuator adapted to be activated independently of the other actuators; and

    a controller configured to activate a first actuator of the plurality of actuators to induce a first vibration at a selected contact location of the input surface and to activate a second actuator to induce a second vibration at a second location;

    wherein the controller is configured to drive the first actuator with a first waveform to produce vibrations, and to drive the second actuator with a second waveform configured to suppress propagating vibrations from the first induced vibration.
