Braille is a system of raised dots that is read with the fingers. It was invented in the early 1800s by Louis Braille of France, who became blind when he was a boy. Each Braille character is made up of six dot positions, arranged in a rectangle comprising two columns of three dots each. A dot may be raised at any of the six positions, or any combination. Counting the space, in which no dots are raised, there are 64 such combinations.
