Braille (Paragraph1)

  Braille is a special system of writing and reading for blind people. Braille letters have groups of bumps or dots. Blind people read these dots by running their fingertips across them to recognize the pattern of the dots. Braille uses a special code of sixty-three characters. Each character has one to six dots that are arranged in a six-position pattern. For example, in the pattern for the letter C, the top two dots are raised, but the lower four are not. Braille gets its name from Louis Braille, a blind science and music teacher who invented this special alphabet in the 1800s. Millions of blind people are able to read today because of this simple yet effective communication system.
