Abstract :
The paper describes the initial stages of the development of microprocessor-based equipment to convert pages of teletext and viewdata information into forms suitable for blind users. The paper concentrates on the development of hardware and software to convert the information into Grade I Braille, which is then displayed on a refreshable row of electrically activated pins, arranged in standard Braille configuration. Initial reactions to the device have been encouraging, and the paper concludes with a discussion of development work now in progress.
