Abstract:
Tactile stimulation interface comprising a support (2), a flexible surface suspended on the support (2) intended to be tactilely explored by an operator, actuators (6) intended to apply a force on the flexible surface (4) and means for controlling the actuators (6), the actuators being located on the contour of the flexible surface. The control means are intended to send, to the actuators (6), signals corresponding to the forces to be applied to the flexible surface (4) according to the tactile stimulation to be generated on the flexible surface (4), the forces being determined by a time-reversal method. The surface (4) comprises at least one sufficiently flexible area, for example of Mylar®, in order for the propagation speed of the waves thus generated to be slow enough to reach sufficiently short wavelengths at low frequencies, thereby substantially improving focusing at resolutions compatible with tactile stimulation.
