Abstract:
1. An apparatus comprising: a touch sensitive visual display including a flexible visual display layer, a touch sensitive layer, and a tactile display layer, the flexible visual display layer configured to render visual images using a matrix of pixels, the touch sensitive layer, having a hollowed effective area, configured to provide touch sensing for non-tactilely enhanced visual images, and the tactile display layer, having an effective core area substantially aligned with the ineffective area of the touch sensitive layer, configured to tactilely enhance at least a portion of the rendered visual images using pistons and to detect contact with the rendered tactilely enhanced visual images; a first display driver to control selective activation/deactivation of the pixels of the flexible visual display layer to facilitate rendering of visual images on the flexible visual display layer; and a second display driver to control the pistons of the tactile display layer to facilitate complementary selective tactile indenting of different portions of a part of the flexible visual display layer that is complimentary to the effective core area of the tactile display layer, said selective tactile indenting to tactilely enhance at least a part of at least one of the rendered visual images.
