Braille - A system of embossed dots, now accepted for all written languages, that enables blind people to read and write. The system is based on 6 raised dots, which can be combined in different ways. There are 2 types of Braille.
In grade I, each symbol represents an individual letter or punctuation mark. In grade II, which is the more widely used, symbols represent common letter combinations or words.
