Braille alphabet. Part of a sheet written in braille with the corresponding characters typed above each braille letter.

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.
