Braille is a tactile representation of alphabetic and numerical symbols using six dots (three rows of two dots) to represent each letter, number, and even musical symbols. This system of delivering words as a series of dots for blind people to read using their fingers to distinguish letters, was created by a young Frenchman named Louis Braille. He became blind as a child due to an accident.
Louis first published his method in 1829. Braille is used by blind and partially sighted people to read the same books, and periodicals as those printed in a visual font. It is used for all European-based languages and has also been adapted to present Arabic, and Asian languages as well. Learning to read and write in braille allows a child to be fully literate and they can excel in learning from any books published in braille form.
