Braille. Braille Brings “Light” into Darkness
摘要
Using their fingers, blind people can be taught to read. They glide their fingertips over dot-shaped elevations on the paper. Palpated, one after the other, these tangible dots translate to letters, words, sentences, or numbers. This internationally accepted method of communication for the blind was developed by the Frenchman, Louis Braille, nearly 200 years ago.
