ACTUATING DEVICE HAVING A TOUCH-SENSITIVE SURFACE WHICH CAN BE MANUALLY OPERATED

摘要

An operating apparatus has a manually operable touch-sensitive surface with an associated actuator system for providing a haptic feedback signal on the basis of a touch, which represents triggering operation, on the surface. The actuator system can be used to provide a haptic feedback signal upon release of the pressure on the surface. The feedback signal is provided on the basis of a sensed change in the contact area of the finger pushing the surface.
