Braille 

Braille is a writing system which enables blind and partially sighted people to read and write through touch. It was invented by Louis Braille (1809-1852), who was blind and became a teacher of the blind. It consists of patterns of raised dots arranged in cells of up to six dots in a 3 x 2 configuration, where each cell represents a letter, numeral or punctuation mark. Some frequently used words and letter combinations also have their own single cell patterns.
