Tactile stimulation interface comprising a support (2), a flexible surface suspended on the support (2) and intended to be explored tactilely by an operator, actuators (6) intended to apply a load to the flexible surface (4) and means of control of the actuators (6), the actuators being situated on the contour of the flexible surface. The control means are intended to send the actuators (6) signals corresponding to the loads to be applied to the flexible surface (4) as a function of the tactile stimulation to be generated on the flexible surface (4), the loads being determined by a time-reversal method. The surface (4) comprises at least one sufficiently flexible zone, for example made of Mylar®, such that the speed of propagation of the waves thus generated is sufficiently slow to attain sufficiently short wavelengths at low frequencies, thereby substantially improving the focusing at resolutions compatible with the tactile stimulation. |
