Braille

Communication Braille

Braille is a tactile writing system used by the blind and the visually impaired, and found in books, on menus, signs, elevator buttons, and currency. Braille-users can read computer screens and other electronic supports thanks to   refreshable braille displays. Refreshable braille displays are electronic devices used to read text tactually that is typically displayed visually on a computer monitor. The refreshable braille display is connected to the computer by a serial or USB cable and produces braille output (with small plastic or metal pins that move up and down to display the braille characters) for the reader.

They can write braille with a slate and stylus, which is are tools used by blind persons to write text that they can read without assistance. Invented by Charles Barbier as the tool for writing night writing. Night writing, also called sonography, was the forerunner of Braille. It was a code that used symbols of twelve dots in two columns of six dots raised on a square of paperboard. It was designed by [|Charles Barbier] in response to Napoleon's demand for a code that soldiers could use to communicate silently and without light at night. The slate and stylus allow for a quick, easy, convenient and constant method of writing with Braille.

Blind persons can also type on a braille writer, such as a portable braille note-taker, or on a computer that prints with a braille embosser. For more information go to [|Braille Technology]

Braille is named after its creator, Frenchman Louis Braille, who went blind following a childhood accident. In 1824, at the age of 15, Braille developed his code for the French alphabet, which is the same alphabet used by English. It was an improvement on its forerunner, night writing.
