Braille is not a language,but it can be used by the blind to read,write,do math and even write music.
Louis Braille,a Frenchman who became blind after a childhood accident,developed Braille in the 1820s.While attending an activity for the blind in Paris,Louis Braille learned that French soldiers used a special code that could be read without a light to send messages at night.Louis Braille was just 11 years old then,but he spent almost nine years using this code to create something that the blind could use to read with their fingers.Louis Braille's system is still used today.
Braille includes letters,symbols(符號(hào)) for numbers,musical notes and other things.To read Braille,people should move their index fingers(食指) from left to right along the symbols on each line of page.Experienced readers can read Braille books as quickly as people who can see.
Braille can be written on paper,too.Today,Braille is even used in computer programs.
