Braille code enables blind and visually impaired to read and write through touch. It was devised by Louis Braille and consists of raised dots arranged in cells. A cell consists of six dots that fit under fingertips, arranged in two columns of three dots each. Each cell represents a letter, a word, a combination of letters, a numeral or a punctuation mark.
