Claim Text:
1. Tactile stimulation interface comprising an element intended to be tactilely explored by an operator, said element intended to be tactilely explored being formed by at least one surface, at least one actuator configured to apply a force on said surface, and a controller for controlling said at least one actuator, said controller being configured to send, to the actuator, signals corresponding to the forces to be applied to said surface according to the tactile stimulation to be generated on the surface, wherein said forces are determined by a time-reversal method, said surface comprising at least one area such that: λ is a wavelength of bending waves being propagated in said area, c is a speed of the bending waves, ρ is a mass per surface unit of said area, and wherein said at least one actuator has a bandwidth extending between 1 Hz and 20 kHz so as to excite a large number of modes specific to said surface.
