A refreshable braille notetaker combines a braille display, a line of small pins that physically rise and fall to render braille characters, with note-taking, calendar, and often web-browsing functionality in one portable device. Many connect to a computer or smartphone to mirror screen reader output in braille rather than audio.
Some blind users, particularly those who are deaf-blind or who simply prefer reading over listening, rely on braille displays as their primary way of consuming digital content, which is one more reason well-structured, screen-reader-compatible markup benefits more than audio-only assistive technology users.
