Among the hand's symbolic meanings, the communicative relevance is the one with greatest
importance for certain people. Braille is a tactile writing system formed by raised
dots arranged in specific places in a 6-position matrix. It's used by the blind and
the visually impaired for books, menus, signs, elevator buttons, and currency. Louis
Braille, a blinded 15-year old boy adapted a 12-dot cell system developed by a French
captain in Napoleon's army to allow soldiers to compose and read messages at night
without illumination. The basic technique was the first raised-dot reading and writing
system. Nearly 300 million people are now visually impaired worldwide: 14% blind and
the remaining have low vision. About 90% of the world's visually impaired live in
developing countries. Historically developing countries like Brazil in 1979 (Fig. 1) encouraged Braille reading to provide an essential skill that would allow visually
impaired children to better compete with their sighted peers in a school environment
and later in the workforce.
