What is Braille?
Definition
Braille is a reading and writing
system used by visually impaired people. The letters of the alphabet and the
numbers are formed from different combinations of a set of six dots arranged in
two vertical rows of three, like a domino. A visually impaired person can
interpret these dots when moving a finger along a line of braille.
A shorthand system
If printed material were
transcribed into braille letter for letter, braille books would be very bulky.
The six dots permit 63 different combinations, and so in addition to letters,
numbers and punctuation marks, there are other symbols for frequent
letter-groups like ING, ER, AND and BLE. There are other devices within the
system which make it into a type of shorthand code.
Grade 1 and Grade 2
If someone learns the letters
of the alphabet and the numbers, this is called grade 1 braille; if you are
able to master the 189 contracted forms, you will know grade 2 braille. Grade 1
is much easer to learn, but grade 2 can save as much as 25% in paper
consumption.
Writing Braille
Braille can either be produced
through a computer translation program, or you can write it by hand in various
ways. When a computer has 'translated' some text into braille, it can be
printed out on a braille embosser. A visually impaired person writing braille
will probably use a small machine which looks rather like a typewriter.
Freedom
As well as providing an open door to all
kinds of literature, braille can be found on clocks and watches, many kitchen
devices, maps and diagrams, labels, card and board games, and so provides a
person without sight with a great deal of freedom and independence.
Moon
Moon is another form of embossed type which
many older visually impaired people find is easier to learn than braille. It
does not require as much sensitivity in the fingertips.
National Library for the Blind
The National
Library for the Blind offer a wide choice of books, in braille and moon, for
both adults and children, similar to the selection found in a local public
library. For example classic novels, Booker prize winners, and modern
bestsellers. Together with biographies, history and travel. Authors like Roald
Dahl, Dick King-Smith and Anne Fine are included in the children's
collection.
