Abstract
A haptic device with ultrasonic actuation, including: a support, a user-interaction element movable at least in rotation and/or translation relative to the support, a first contact surface that moves as one with the interaction element, a second contact surface that moves as one with the support, resonators, and a control unit that excites the resonators at at least one resonance frequency, generating a vibration mode in a plane and an ultrasonic lubrication phenomenon between the first contact surface and the second contact surface.
Claims14
A haptic device comprising:
- a support;
- a user interaction element configured to be at least rotationally and/or translationally moved with respect to the support;
- a first contact zone movably secured to the user interaction element;
- a second contact zone movably secured to the support;
- at least one position detector detecting a position of the user interaction element relative to the support;
- at least one first resonator;
- a control unit configured to energize the resonator at at least one resonance frequency generating an in-plane vibration mode and occurrence of a vibration lubrication phenomenon between the first contact zone and the second contact zone.
