BACKGROUND

The Braille History starts when Louis Braille had an accident in his father´s workshop and he lost one eye. Finally, he was a totally blind person when he was 3 years old. In the 19th century, Louis Braille designed his system with 6 dots in relieve when he was fifteen years old. This system has 63 combinations. These dots are in two vertical rows of three dots each one.  

Later, Barbier, a captain of the French army thought a night writing system about dots in relieve that soldiers could use to communicate silently. The Braille´s system was based on a code of the army.

The Braille is a system that is based on touch through dots in relief. In 1840, The Braille´s system was accepted officially.

We are going to pay attention to sixty years ago, approximately.

This system can be reproduced manually with a punch and a metal plate.

 

+However, in 1951, it produced a great challenge. It appeared Perkin´s machine which lets write quickly in  Braille. It is similar to a manual typewriter. It allows a better quality of dots and facilitates an association of alphabet.

This machine has an electronic accessory Braille´n-printer, it allows the conversion of normal texts (ink, pictures…) into a braille text with a printer. It is a printer used for Perkin machine.

+Later, in 1988, the Braille´n speak was created, which processes the information and records electronically what said, it has a similar keyboard to Perkin´s machine. Its main functions are reading and writing.

+In 1970, it appeared the microelectronic. After, it appeared the typhlotechnology in Spain.

According to ONCE´s website, "typhlotechnology has all techniques, knowledges and resources for blind people can  use the technology”.

With Tiflotecnología appears:

-Readers of screem

-Magnifier of screem

-Recognition of printed texts

-Braille Indez printer: It prints with the dot system.

-Thermoform Braillon Duplicator: to make different copies in relieve.

-Converters

-Specific mechanism (Mobile speak, Mobile magnifier, calculator,etc).

-And so on.

These systems are based on technology and blind people could have improved their speed in reading.
