Abstract
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.
