A display device including a deformable surface, including: plural actuators including mobile elements that can be moved to deform the deformable surface, the mobile elements being distributed in a space occupied by the deformable surface; a set of position sensors for sensing the position of at least one touch, and distributed in the space occupied by the deformable surface; and an elastic flexible membrane placed against the mobile elements, extending through the space occupied by the deformable surface and configured to accompany deformation of the deformable surface. The set of sensors is secured to the elastic flexible membrane and distributed in a regular manner in the space occupied by the deformable surface in an array of electricity conductors configured to accompany deformations of the elastic flexible membrane.

Display device having a deformable surface and position sensors

An haptic interface including a knob manipulated by a user, a rotation shaft with a longitudinal axis to which the knob is fixed in rotation, an interaction element with a magneto-rheological fluid in rotation with the shaft, the fluid, a system for generating a magnetic field in the fluid, and a control unit capable of generating orders to the system for generating the magnetic field to modify the magnetic field. The system includes a coil type mechanism generating a variable magnetic field, and a permanent magnet type mechanism generating a permanent magnetic field.

Force feedback interface with improved sensation

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.
