Video: The process of creating a Braille system for the blind

In the early 1800s, when Napoleon's war took place in central Europe. At midnight, Captain Charles Barbier, the Napoleon servant, was trying to spread the message to one of his soldiers. But sending information via mail to the front line can be dangerous for the recipient, lighting candles to read the letter can reveal the location to the enemy.

Braille.

In a sudden moment, Barbier poked a series of holes in the paper with the tip of a knife, creating an encrypted message that could be decoded with his fingertips even in the dark night. The way of writing that night was never transmitted in the army.

In 1821, Barbier introduced it to the Royal Academy for Blind Youth in Paris, France in hopes of finding a way to use the new method of communication he created.

There, a boy named Louis Braille did this.

It took Louis several years to perfect Barbier's idea, creating an orderly alphabet that fits in the standard 6-dot set, which became popular.

Today, Braille systems are globally accepted for visually impaired people, suitable for 130 languages.

Braille is a braille system for blind people with each word made up of 6 points, arranged in a rectangular frame of two columns, three lines.
