Abstract

The system has a touch-controller (14) i.e. touch-screen controller, coupled with a user contact interface e.g. resistive touch screen, to obtain and produce acquired data e.g. contact coordinate data and print data, and output a trigger signal in response to the data. A transmission path couples the touch controller with a driver element controller that is coupled with an interface surface area. The driver element controller receives the trigger signal from the touch controller via the transmission path, and outputs a drive signal to a driver element (24) in response to the trigger signal. An independent claim is also included for a method for providing a haptic feedback.
