Braille is a system that uses combinations of raised dots to spell letters and numbers. It's used by people who are blind or partially sighted to help them read and write. Braille is not actually a language — it's a system of writing. 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.
