The Free On-line Dictionary of Computing (30 December 2018):

braille

    /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.
