Abstract: A control device with haptic feedback includes a vibrating plate having a touch surface provided with touch sensors and capable of being vibrated at an ultrasonic frequency by electromagnetic actuators controlled by a control electronics, so as to generate an ultrasonic lubrication effect on the touch surface. A three-dimensional touch interface is fixed to and integral with the touch surface, configured to communicate vibrations of the ultrasonic lubrication effect from the touch surface to the finger of a user by means of the three-dimensional touch interface.
