Braille is a tactile writing system used by blind and visually impaired people. It was developed in the 19th century and uses patterns of dots to represent letters and numbers. Louis Braille improved on a previous system to develop the 6-dot braille cell that is used today. Braille can be read through touch and allows blind people to read and write. It is produced using braille embossers or printers and comes in various formats including braille books, notes, and computer displays.
