Claim 0:
1. A haptic interface comprising:
a support;
at least one plate comprising a first face forming a surface for interaction with at least one member of a user; and
at least one actuator adapted to apply a vibration to said plate; and
a control module of said actuator,
wherein said support includes at least two support elements supporting the plate so as to delimit between the two support elements a strip extending along a first direction,
wherein said actuator is located opposite to the plate with respect to the interaction surface, and
wherein said control module being configured to generate control signals to said actuator at first frequencies lower than a cutoff frequency of a first propagation mode of said plate, so that the actuator generates evanescent waves in the plate.
