Refreshable Braille Displays are electronic devices that are used to read text that a computer sends to the monitor. The device is connected to the computer by a serial cable and produces Braille output on the Braille display. Refreshable Braille displays only read one line of text at a time. These displays generally include directional keys which allow the user to navigate through a document. Larger displays (80 cells) also include a cursor routing function. Each cell contains eight small pins, allowing eight dot computer Braille rather than the six dot Braille we are used to seeing.

Some portable note takers that have refreshable Braille can also be used as a refreshable Braille display for a PC computer.

Points to ponder - Questions to consider when shopping for a refreshable Braille display

  • Is it compatible with your computer's platform?
  • How many Braille cells are active on the display?
  • Does it have its own power source?
  • Does it have extra keys that can be programmed with additional commands?
