While depicted here as images, the braille alphabet is designed so that each of six different dots (organized into two columns and three rows) can be raised so that a blind person could physically sense them. The braille communication system uses various combinations of raised dots to represent both letters and numbers. For instance, a single raised dot in the top left corner of a letter block (or "cell") represents the letter A. Two dots, one in the top left and one in the middle left of a braille cell represents the letter B. There are 64 possible combinations of braille "cells."The braille alphabet was developed by Louis Braille (1809-1852) in France. Louis Braille lost his sight as a young child and a young adult developed his braille communication system as a way of communicating so that others who were blind or had extremely poor eyesight could read and write and even print. Louis Braille derived his simple braille type from a more complex method devised by Charles Barbier.
Special machines, similar to typewriters, can create the raised dots for the blind to write, print, and read.
