Braille
A term which is useful to know is "accessible publishing": Accessible publishing means books and other texts are available in formats designed to aid or replace the reading process. Examples are: varieties of larger fonts, specialised fonts for certain kinds of reading disabilities, Braille, e-books, and automated Audiobooks and digital talking books. This means that Braille is only one way for sighting-impaired people to go; also that there are many more partially sighted people than registered blind people. The partially sighted obviously have more choices.
