Abstract

A system has been developed for allowing blind people to access unlimited documents by using a tactile Braille display device with relay switch. The proposed system presents a machine which renders the text from a document as tactile Braille cells. The implementation of refreshable Braille tactile displays is designed using relay switches and its advantageous features in the fabrication which is easy in the implementation and less cost. The tactile cell in the system of Braille device is based on tactile sensation, which changes the visual sensation of the person’s with sight. The tactile sensation is achieved using fingertips running over the round-tipped pins mounted over the movable part of the relay switch. The system first acquires an image of the set type document using a camera, then character from the image is recognized using OCR. The recognized characters are coded and then send to the tactile board.
