  • Patent number: 11960686
    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.

  • Patent number: 10860107
    Abstract: A touch-sensitive interface has a contact surface that is able to be touched by an effector (e.g., a finger). The interface includes actuating transducers (e.g., piezoelectric transducers) allowing a standing flexural wave to be formed, in a resonant mode, extending over the length of the slab. The interface includes a detector for measuring the amplitude of the wave, and a detecting circuit for determining an attenuation signal, when the contact surface is touched by an effector. It includes a processing circuit for estimating a magnitude of the force exerted by the effector on the contact surface.
