3.1: Notes About Braille

Braille is a tactile code that is widely used by visually impaired individuals to read and write. Each character, or “cell,” is made up of six dot positions, arranged in a rectangle containing two columns of three dots each. There are several different grades of Braille in use. Grade 1 Braille uses one character per cell. Experienced Braille readers usually prefer to use grade 2 Braille, in which several letters are combined into a single cell.
