Braille is a tactile writing system used by people who are blind or visually impaired. It is named after Louis Braille, the French man who invented it. The system is used by blind people to read and write. The Braille system uses a set of raised bumps or dots that can be felt with a finger. Each set of dots is a character in an alphabet, and the numbers and some punctuation. Braille is used with different languages today. In each language, the letters are encoded differently, depending on the alphabet. The list of codes is known as braille code, or code page. There are also different braille codes in use for special purposes, like writing shorthand, mathematics or music. Close-Up. Pack 2 Full HD Clips.
