Computing Dictionary
 
 Definition: 

/breyl/ (Often capitalised) A class of writing systems, intended for use by blind and low-vision users, which express glyphs as raised dots. Currently employed braille standards use eight dots per cell, where a cell is a glyph-space two dots across by four dots high; most glyphs use only the top six dots.

Braille was developed by Louis Braille (pronounced /looy bray/) in France in the 1820s. Braille systems for most languages can be fairly trivially converted to and from the usual script.

Braille has several totally coincidental parallels with digital computing: it is binary, it is based on groups of eight bits/dots and its development began in the 1820s, at the same time charles babbage proposed the difference engine.

Computers output Braille on braille displays and braille printers for hard copy.
