ABSTRACT:
A Braille display cell which may be embedded in one of a plurality of keys that are used to provide input to a digital data processor. Cursor controls identify a location in text containing characters, and, in response thereto, the processor produces a Braille actuation signal which identifies the character located at said position. The Braille actuation signal, in turn, generates a Braille indicator of the character on the Braille display cell. With the assistance of the cursor controls, the text can be scanned to cause the Braille indicators corresponding to the characters in the text to appear sequentially on the Braille display cell thereby displaying the text in Braille so that said text can be read tactilely.
