World Braille Day

Braille is a code that uses bumps and indentation on a surface to represent letters, which can be recognized by touch. Louis Braille, a French man who was blinded in an accident at a very young age, invented it.

Before Braille invented this form of communication, visually impaired people read and wrote using the Haüy system which embossed Latin letters on thick paper or leather. This was a complicated system that required much training and only allowed people to read, not write. Discouraged by this, Braille at the age of 15 invented the Braille code.

While there are now several different versions of Braille, Louis Braille’s code was arranged in small rectangular blocks called cells with raised dots in a 3 x 2 pattern. Each cell represented a letter, number or punctuation.

Since Braille is a code, all languages and even certain subjects like mathematics, music and computer programming can be read and written in braille.
