I've found some helpful information on
http://www.nationalbrailleweek.org/page/braille-facts about braille that I thought people might like to read.
What is Braille?
Braille is the system of touch reading and writing that utilises raised dots to represent the letters of the print alphabet for persons who are blind or visually impaired. The Braille system also includes symbols to represent punctuation, mathematics and scientific characters, music, computer notation, and foreign languages.
Why is Braille used?
Braille is not a language. It is a code by which all languages may be written and read. Through the use of Braille, people who are blind are able to review and study the written word. It provides a vehicle for literacy and gives an individual the ability to become familiar with spelling, punctuation, paragraphing and other formatting considerations.
Who uses Braille?
Braille is used mainly by people who are blind, deafblind or visually impaired. It is critically important to the lives of these people as the ability to read and write in Braille opens the door to literacy, intellectual freedom, equal opportunity, and personal security. Teachers, parents and others who are not visually impaired ordinarily read Braille with their eyes.
