Braille is the internationally widespread reading and writing system for blind and partially sighted people. The system was founded in 1825 by Louis Braille , who lived in France and himself was blind.
Braille is not a language, it is just another way to read and write a language.
Braille consists of arrangements of dots which make up the letters of the alphabet, numbers and punctuation marks. The basic Braille symbol is called the Braille cell.
Due to the reason that there are differences in Braille in different countries, the type of Braille letter (size of Braille cell) has to be standardized.
