Braille is a tactile reading system that was invented in France in the mid-1800s and is named for its inventor, Louis Braille.
Braille enables children who are unable to read print to become literate and helps adults who lose the ability to read, due to blindness or low vision, to continue enjoying books, newspapers, and magazines.
The braille alphabet is based upon a "cell" that is composed of 6 dots, arranged in two columns of 3 dots each. Each braille letter of the alphabet or other symbol, such as a comma, is formed by using one or more of the 6 dots that are contained in the braille cell. (The letter "z" is pictured at left.) The chart below provides a good example of the design of the braille alphabet.
