A tactile reading format used by people who are blind, deafblind or who have some visual loss. Readers use their fingers to ‘read’ or identify raised dots representing letters and numbers. Although originally intended (and still used) for the purpose of information being documented on paper, braille can now be used as a digital aid to conversation, with some smartphones offering braille displays. Refreshable braille displays for computers also enable braille users to read emails and documents.
