A haptic interface including an element that interacts with a user; a rotation shaft with a longitudinal axis to which the user interaction element is fixed in rotation; a fluid interaction element, the fluid interaction element being fixed in rotation to the shaft, the fluid being of magneto-rheological type, a system generating magnetic field in the fluid; and a control unit capable of generating orders to magnetic field generation system so as to modify the magnetic field. The interaction element includes a cylindrical wall of revolution with a longitudinal axis, including through openings and/or patterns in relief.
