What is a braille terminal?
A refreshable braille display, also known as a braille monitor, braille terminal or simply a braille display, is a peripheral device that allows blind or visually impaired people to interact with a computer, tablet or smartphone. A braille monitor uses the braille system that blind people use to read. Raised dots spell out text that the user traces a finger over to read. A braille display consists of a rectangular device with grouped rows of pins. The pins are raised and lowered to spell out letters in the braille alphabet. Braille displays use groups of 40 by 80 pins, or braille cells. Models for note-taking use cells of 10 by 40 pins. A user reads the letters by touch.
