Most people have some association of braille with blind people reading or perhaps have seen photographs of Helen Keller reading with her fingertips. But precisely what is braille?
Braille is a tactile system for representing the written word that is used as an alternative to reading and writing print by people who are blind or visually impaired. It is not a language, but rather is a code—a system for representing the alphabet and words—in a language such as English. For people who use braille, it provides a means of independent literacy—that is, they can read and write without assistance from anyone else. The braille code used today in the United States was invented by a Frenchman, Louis Braille, in the 1800s.
