Inkprint

Devices that permit direct reading of inkprint would be far more useful, since then the entire library of published literature is then opened to a deaf-blind person, while only a relatively small selection can ever be put into braille.

“Twin-Vision” books are inkprint with braille overlays that help young children learn that words can be either seen or touched.

A Braille library looks certainly dull and cold to the sighted person's eyes, used to inkprint libraries, since the Braille one looks more like a shelved collection of large bound legal documents.
