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.
Claims14
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.
