Abstract:
1. A touch feedback system comprising: a user touch interface comprising an interface surface and a drive element coupled to the interface surface, wherein the interface surface is configured to sense a touch event and to transmit sensed data in response to the determined touch event; a touch controller coupled to the user touch interface to receive the sensed data and to generate and output a trigger signal in response to the sensed data, the trigger signal including a bit sequence corresponding to a haptic response; a transmission path directly coupling the touch controller to a drive element controller; and the drive element controller coupled to the touch controller and to the interface surface, wherein the drive element controller is configured to receive the trigger signal from the touch controller via the transmission path and to select a drive signal based upon the bit sequence and to output a drive signal to the drive element in response to the received trigger signal, wherein the touch controller includes a register or flag for enabling/disabling the generation of the trigger signal; a system host controller coupled to the touch controller to control the register or flag, wherein the system host controller does not generate and output a control signal to the drive element controller.
