What is Braille?

Braille is a tactile writing system that was developed in the year 1824 by Louis Braille a Frenchman with the aim of allowing those who are low-minded crap to read and write. Louis developed Braille after being involved in an accident during his childhood that led him to lose his sight. Traditionally, Braille has been written with embossed paper. Nowadays, braille users can use updatable Braille displays to read electronic media and computer screens. They can use the original stylus and slate to write in Braille or to write it on a Braille writer.

Chronology

Louis improved the night by writing a code invented by Charles Barbier for the military. Louis improved this code by developing the code for the French alphabet and subsequently included a musical notation in his system published in 1829. In 1837 the second edition was published, which was the first small binary writing system in the it was modern. These characters consisted of rectangular blocks with small bumps, which are cells with raised points. The characters are distinguished from each other by the disposition and number of these points.

Braille Illustrations

Braille cells do not appear exclusively in Braille text, illustrations and graphs can be embossed with solid lines or lines consisting of series of arrows, points or points that are larger than Braille points. A complete Braille cell has six raised points arranged in two columns and each column has three points. The numbers from one to six identify the position of the point using one or more points one with the combinations 64. You can use a cell for different functions such as representing a number, a letter, a word or a punctuation mark.

Previous Braille system

In the original Braille system, points were assigned to letters based on their order in the French alphabet. The letters aj of the alphabet use the positions of the four upper points. Since it is not easy to delete when you make a mistake while writing in Braille, all six points are used to overwrite the error. Eight point codes have been obtained by extending the braille to use it with braille embossers, in which the additional points are added in the lower part of the cell creating a matrix of four points of height and two points of width.

Contractions

Literal contractions are used in the Braille script which refers to the Braille contracted with the aim of reducing the amount of paper needed to produce a Braille book and also helps facilitate reading. The Braille grade 2 is the Braille that is completely contracted, while the uppercase and numeric signs are used in Grade 1. The linguistic structure of a word is taken into account when using the contraction rule and, therefore, this rule cannot be used if its use can change the braille form of a word.

Master the Braille

Braille readers must develop the ability to create uniform and uniform pressures when passing their fingers through words. A study by Lowenfield and Abel was used to show that individuals who use both of their indexes read better and faster than others who have used other methods.
