Communication device for the blind

Abstract

Abstract Communication device for the blind providing coarse and fine scanning (reading) of documents. For this purpose it has a Braille dot panel (8) and an optical scanning device (3) for documents together with a Braille keyboard (10) and function keys (11) combined together in a case (1, 1') to form a portable device. The Braille keyboard (10) and the function keys (11), in conjunction with an edit line (9) of the dot panel (8), permit interactive communication between the user and the device, in particular switching over from coarse scanning of the document to fine scanning of a part of the document selectable by the user by appropriate control of the scanning device (3). Provision is also made for connection of the device to conventional data processing equipment via standard interfaces. <IMAGE>
