Abstract
A tactile display reads out information corresponding to at least a portion of an image appearing on a computer screen comprising a 2-dimensional array of pixels. The tactile display comprises at least one array of tactile output elements, each element corresponding to at least one pixel of the computer screen image and movable, in response to an input representative of a value of a property of the at least one pixel, to a predetermined one of a plurality of discrete, tactilely-recognizable positions. The positions of the plurality of tactile output elements provide a tactilely-recognizable pattern representative of the information on the screen. A touch sensor may be operatively associated with at least one of the tactile output elements to provide an output in response to a user's touch of the associated tactile output element.
