Time reversal interface generating an acoustic lubrication
A tactile stimulation interface comprising a surface explored by touch by means of a finger of a user, actuators applying forces on said surface, and control means of the actuators, said control means sending, to the actuators, signals corresponding to the forces to be applied to said surface, the f...

| description | A tactile stimulation interface comprising a surface explored by touch by means of a finger of a user, actuators applying forces on said surface, and control means of the actuators, said control means sending, to the actuators, signals corresponding to the forces to be applied to said surface, the forces being determined by a time reversal method, means for detecting the contact of the finger with the surface and for monitoring the movement of the finger on the surface. The control means are capable, in order to produce an acoustic lubrication effect in at least one given area of the surface, of generating a signal formed from a convolution of a pulsed response returned by a continuous function representative of the acoustic lubrication effect. |
