Tactile stimulation interface using time reversal and providing enhanced sensations

A tactile stimulation interface includes a surface which the user explores by touch with the fingers, an actuator for applying a force to the surface, and a controller for controlling the actuator. The controller sends the actuator signals corresponding to the forces to be applied to the surface according to the tactile stimulation to be generated on the surface, the forces being determined by a time reversal method. The controller is configured such that, for at least one given tactile pattern, the actuator is controlled such as to generate pulses, in at least one area of the surface, by focusing at least one acoustic wave at a point. The location of the point on the surface varies over time, such as to provide tactile stimulation for the finger according to the given tactile pattern.
