Braille is a system of touch reading and writing for blind persons in which raised dots represent the letters of the alphabet. It also contains equivalents for punctuation marks and provides symbols to show letter groupings. Braille is read by moving the hand or hands from left to right along each line. The reading process usually involves both hands, and the index fingers generally do the reading.
What Is Braille?
The braille system is a tactile method of reading and writing for the blind. Named for its inventor, Louis Braille, it employs groups of dots to represent printed letters and numbers. The dots in the first column are numbered one through three and the second, four through six. These patterns are easily identifiable by touch. Although beginning braille readers generally prefer uncontracted braille, contracted braille tends to be the default for documents and publications. A typical braille page contains forty braille characters per line and twenty-five lines.

The specific code used in the United States has been English Braille, American Edition but as of the main code for reading material is Unified English Braille, a code used in seven other English-speaking countries. Braille symbols are formed within units of space known as braille cells.

Braille is named after its creator, Louis Braille , a Frenchman who lost his sight as a result of a childhood accident.
