Claim 0:
1. A control device with haptic feedback, comprising a vibrating plate having a touch surface provided with touch sensors and vibrated at an ultrasonic frequency by electromechanical actuators which are controlled by control electronics so as to generate, on said touch surface, an ultrasonic lubrication effect, and further comprising a three-dimensional touch interface that is devoid of any actuator and of any moving part and is fixed and secured to said touch surface by an adhesive chosen to transmit the ultrasonic vibration generating the ultrasonic lubrication effect from said touch surface to said three-dimensional touch interface, wherein said ultrasonic lubrication effect is communicated from said touch surface to a digit of a user via said three-dimensional touch interface when said digit of the user touches or swipes said three-dimensional touch interface.
