Abstract
A interaction device includes a touch-sensitive surface which generates input data when the touch-sensitive surface is in contact with an actuator, a frame fixed to a periphery of the touch-sensitive surface, an actuator which generates a reaction force as a function of the input data, and a support to which the actuator is coupled. The frame and the touch-sensitive surface are arranged to form a rigid assembly which has a resonant frequency of a few hundred Hertz. The actuator is directly coupled to the frame to displace the rigid assembly relative to the support, and the resonant frequency of the actuator is substantially equal to the resonant frequency of the rigid assembly.
