Braille Will Soon Be Required On Every One Of The Fire Door Signs
Braille, universally accepted system of writing used by and for blind persons, invented by Louis Braille in 1824. It consists of a code of 63 characters, each made up of one to six raised dots arranged in a six-position matrix or cell. The characters are read by passing the fingers lightly over the manuscript.
