? What is Braille
Braille is a tactile system of reading and writing for use by the blind or visually impaired.
_The reason for the name Braille system.
Braille is named after its creator Louis Braille (1809 – 1852). In 1824, at the age of 15, Braille presented his ideas for a system of tactile code that could allow blind people to read and write quickly and efficiently.
Braille is not a language, it is another way to read and write a language.
Characters are represented by an arrangement of raised dots.Each braille character or cell is made up of six dot positions, arranged in a rectangle comprising of two columns of three dots.
A dot may be raised at any of the six positions to form many combinations. Counting the space in which no dots are raised, there are sixty four such combinations.
Braille font cellFor reference purposes, a particular combination may be described by naming the positions where dots are raised, the positions being universally numbered 1 through 3 from top to bottom on the left and 4 through 6 from top to bottom on the right for example, dots 1-3-4 would represent a cell with three dots raised, at the tip and bottom in the left column and on the top right of the right column.
Braille characters are three dimensional tactile bumps on a medium such as paper or board. In order for these bumps to be represented, viewed, checked and controlled on digital artwork the designer places appropriately sized and spaced filled circles on the artwork layout. The circles can be constructed from a simple grid of dots, but the most efficient method of creating braille print artwork is with a braille font.
Grade 1 braille.
It is possible to transcribe braille by simply substituting the equivalent braille character for its printed equivalent, such a character-by-character transcription, known as Grade 1 braille. Grade 1 braille is recommended for pharmaceutical and medicines packaging.
The braille alphabet, numbers and symbols of Grade 1 (uncontracted braille) differ around the world.
Grade 2 braille.
Braille characters are much larger than their printed equivalents, and the standard 28 cm × 28 cm page has room for only 25 lines of 40 characters. To reduce space and increase reading speed, virtually all Braille books are transcribed in what is known as Grade 2 braille, which uses a system of contractions to reduce space and speed the process of reading.
Grade 3 braille.
is a system that includes many additional contractions, almost a shorthand; it is not used for publication, but is used mostly for individuals for their personal convenience.
Why are there contractions in braille?
Braille takes up more space than printed text. For this reason, braille uses short sequences, called contractions, to take the place of words or letter groups that commonly occur in the language. For example, “the” is usually just one character in braille. The contractions save space, and they also improve the speed of writing and reading.
