What is Braille?

What is Braille?: Braille is the system used by blind people to read. This, a writing system works by allowing characters to read embossed using the fingers.
Each of these characters or cell contains six positions of points positioned in boxes, which are in two columns of three dots each. Each of these points can be raised (embossed them), so that the fingers, the blind person can feel this bump. When no relief, means that there is a space.
The first column contains numbers from 1 to 3. The second, which is positioned on the right, contains the numbers 4 to 6. Letters to be developing, carrying out various combinations of relief, with the various existing points.
With respect to the history of braille, this originally born, through the request of Emperor Napoleon Bonaparte, creating a silent communication system for soldiers, which could be read without light. It was called the night reading.
But this reading system, proved too complex, so that soldiers could read quickly the different notes. Apart from the resort that was the very act of learning to read under this system. Thus, as the military academies, rejected the project.
In the mid-nineteenth century, in the year of 1821, gave birth to the creation of Louis Braille, who having been blinded in childhood, had managed to create a speed reading system and easy to learn, for people who are blind. This person worked at the National Institute for the Blind in Paris. His idea was generated from previously developed systems for the military. Thus, as he realized that the previous system failed because their signs were very large, and to immediately determine the distribution of the relief using your finger, without having to move it. Which made it extremely slow. Its creation and great contribution was to develop or Braille cells, that is, the six points, which shape the letters, through the relief thereof.
Thus, as Braille, may be considered as the first binary encoding, the world. This system also can be used for the purpose of reading music and even mathematics.
The forms used to write Braille, are those described below. This the manual way, using along with a punch combinations to be forming. Are typewriters of this system (do not forget that the conventional typewriters, born by the request of an earl, a machine to write her daughter who was blind). There are also Braille printers, which can be connected to a computer. The latter is the modern and fast solution to the issue.
Regarding Braille characters, they come to occupy much more space than conventional print. This is how a typical page of Braille, which can grow up to 28 centimeters, for another 28, only gets to be room for 25 lines of 40 characters each.
