Question

Guys explain me about Braille scripts . ☺

Answer 1

The Braille system is a way of writing things. It is named after Louis Braille, the French man who invented it. ... The Braille system uses a set of raised bumps or dots that can be felt with a finger. Each set of dots is a character in an alphabet, and the numbers and some punctuation.

Answer 2

Braille is named after its creator, Louis Braille, a Frenchman who lost his sight as a result of a childhood accident. In 1824, at the age of fifteen, he developed a code for the French alphabet as an improvement on night writing. He published his system, which subsequently included musical notation, in 1829.[1] The second revision, published in 1837, was the first small binary form of writing developed in the modern era.

These characters have rectangular blocks called cells that have tiny bumps called raised dots. The number and arrangement of these dots distinguish one character from another. Since the various braille alphabets originated as transcription codes for printed writing, the mappings (sets of character designations) vary from language to language, and even within one; in English Braille there are three levels of encoding: Grade 1 – a letter-by-letter transcription used for basic literacy; Grade 2 – an addition of abbreviations and contractions; and Grade 3 – various non-standardized personal stenography.

Braille cells are not the only thing to appear in braille text. There may be embossed illustrations and graphs, with the lines either solid or made of series of dots, arrows, bullets that are larger than braille dots, etc. A full braille cell includes six raised dots arranged in two columns, each column having three dots.[2] The dot positions are identified by numbers from one to six.[2] There are 64 possible solutions using zero or more dots.[3]A cell can be used to represent a letter, number, punctuation mark, or even a word.[2]
