Patent

CA 2735638

The invention relates to an interaction device comprising a touch-sensitive surface (1) capable of generating input data when said touch-sensitive surface is in contact with an actuator, a frame (2) fixed to the periphery of said touch-sensitive surface (1), an actuator (3) capable of generating a reaction force as a function of said input data and a support (4) to which said actuator (3) is coupled, characterized in that the frame (2) and the touch-sensitive surface (1) are arranged so as to form a rigid assembly (1-2) that has a resonant frequency of a few hundred Hertz and in that the actuator (3) is directly coupled to the frame (2) to displace the rigid assembly (1-2) relative to the support (4), the resonant frequency of said actuator (3) being substantially equal to the resonant frequency of the rigid assembly (1-2). The invention advantageously applies to the haptic touch-sensitive display devices that have a diagonal with a dimension greater than inches.
