The Braille method is a reading system for the blind or blind person, is known by the Braille method, and the system arose from reading in the dark developed by Charles Barbier, designed for military use.

The Braille system uses a series of raised dots that are interpreted as letters of the alphabet and used by blind people who learned the method. The existence of Braille, opens a whole world to those who have serious visual disabilities and, as if that were not enough, technology integrated Braille to modern gadgets.

Origin

In 1825, Louis Braille, a blind Frenchman after an accident in his childhood, became interested in a system used in military units and that transmitted instructions using a tactile code to be deciphered based on raised points, with the idea of hiding them from the enemy.

From then 13 years, Louis Braille was dedicated to simplify it, adapting it to the abilities and needs of blind people, who use it not only to read, but also to write and perform in different areas of knowledge.

¿How Does it Work?

The Braille system is based on six points that are distributed in different ways, falling within what is considered a binary system. It is not a language, but an internationally recognized alphabet, capable of displaying letters, numbers and even signs, which makes it really complete.

In total, there are 256 characters in Braille, many of which owe their meaning to the one preceding or following it. There is even a translation of musical notes into Braille

Each character is based on six points that are arranged in two parallel rows of three. Depending on what you want to represent, certain points are highlighted and, when you touch them, who knows how to interpret Braille detects which letter, number or sign corresponds to.

Although Braille is a universal alphabet, there are small variations in each language, adding letters or replacing them with others, typical of a certain language. Alphabets such as Japanese and Chinese, combine sounds in braille characters, since they are based on symbols.
