Abstract
This is an entirely new type of tactile display based upon cuneiform writing concepts which is an alternative to Braille. This invention uses electromechanical components to display a tactile coding of letters, numbers and symbols using rotating linear components and pointer variations of these. These pointer parts rotate on the surface of the device. A user places fingers or skin on the surface and by feeling the direction in which the components are pointing determines the coded symbol.
