Abstract
An apparatus providing a three dimensional tactile sense on a display of an electronic device. The apparatus comprises two layers. The bottom layer is a set of channels that form a matrix along x and y axes. The top layer comprises a matrix of small transparent columns. When the user interface provides the sensation of a three dimensional surface, the corresponding x and y coordinates that are mapped to the three dimensional surface are inflated. The change in volume forces a subset of columns upward in the direction orthogonal to the plane of the screen.
