Braille refers to a system of making raised dots on paper to form letters and words that are read by the blind with their fingertips.
Arrangements of dots which make up letters of the alphabet, numbers and punctuation marks. The basic Braille symbol is called the Braille cell and consists of six dots arranged in the formation of a rectangle, three dots high and two across. Other symbols consist of only some of these six dots. The six dots are commonly referred to by number according to their position in the cell
