Tactile writing system using raised dots that is used by blind people.
Braille is traditionally written on embossed paper, where it uses 6 dots per character. On a computer, a screen reader can turn screen content into Braille, which is displayed on a refreshable Braille display, which uses 8 dots per character. Braille can also be produced with a slate and stylus, with a Braille writer, e.g. a portable Braille note-taker, or on a computer that prints with a Braille embosser.
