Abstract

Tactile interface comprising a panel (1) having an interactive surface (2) with one or a plurality of exterior elements, comprising a plurality of interactive areas (Z1, Z2, Z3, Z4) arranged relative to one another, such that they cover substantially the whole of the interactive surface (2) and a plurality of actuators (A1, A2, A3, A4) in contact with the panel, control means (6) of actuators configured to send control signals to the actuators, comprising means for calculating (8) said control signals, said calculating means (8) executing an inverse filtering operation, so as to emit, from a desired displacement or displacements of one or more interactive areas (Z1, Z2, Z3, Z4), control signals compensating at least partially the distortion, reverberation and propagation of waves.

Dependent claims

An areal device for localized deformation comprising:

a panel having an interactive surface with one or more exterior interactive elements, comprising at least one interactive area with the exterior;
at least one actuator capable of causing deformation in a direction orthogonal to the plane of the panel in the interactive area, the at least one interactive area being located in the near field of the actuator;
at least one detector for detecting the contact between the at least one interactive area and an exterior interactive element;
and
control means of said at least one actuator being configured to send control signals to said actuator, comprising calculation means of said control signals, said calculation means executing an operation of inverse filtering, so as to emit from a desired displacement of said area, control signals at least partially compensating the distortion, reverberation and propagation of waves,
wherein the at least one interactive area is located with respect to the actuators at a smaller distance or a distance equal to a wavelength of the control signals and/or dimensions of the actuators in direction of the interactive surface.
