'Braille'
Tactile writing system used by blind people
A system of raised dots representing the letters of the alphabet, punctuation and numbers. Braille enables blind people to read by touching and to write using an embosser.
There are several forms of Braille, including the most common, Literary Braille. Grade 1 Braille is where each print letter is represented in one Braille cell. More experienced Braille users may read Grade 2 Braille. This is where common words or groups of letters (for example, 'and', 'the', 'ing') are combined into one Braille cell. The advantage of Grade 2 Braille is that it takes up less space than Grade 1. Additional codes have been developed for musical notation, work in math or science, and computers. Foreign languages have their own codes as well.
Braille takes its name from the French inventor; Louis Braille.
