Braille. Fingers of a blind boy moving across a page of text written in braille,which is a set of mathematics questions. The braille writing and reading system was devised by the French teacher Louis Braille (1809-1852),who himself was blinded at the age of three. It is a universally accepted system that enables blind people to have access to written language. It consists of a sequence of cells,each of which contains a pattern of raised dots that can be sensed by touch through the fingers. Different patterns of dots represent letters,numbers,punctuation marks and several short words | |
