Projects / libbraille


Libbraille makes it easy to access Braille displays and terminals. It can write text on a Braille display, directly draw Braille dots, or get the value of pressed keys. It is compatible with a wide range of Braille displays, and can autodetect some of them. A virtual GTK+ display is provided so that developers can test how their application would be rendered in Braille.
