Available in BRLTTY, BrlAPI is a way for your applications or screen readers to easily output braille without having to tackle all the nasty technical details, through the use of a library which forwards the braille output to the BRLTTY daemon. See the documentation of latest stable version and the reference manual


NEW: in the new release (0.5.0), BrlAPI has Python, Java, Tcl, OCaml and CLisp bindings!

BrlAPI is already used by leading screen readers like Gnopernicus, Orca, LSR, and soon Serotek's System Access and probably NVDA.

Several programs were written for transferring files to/from braille devices:

Accessibility Howto

There are two generic guides: one for developers, and one for users. They are a bit outdated, but they still give a good idea of the needs.

For GULs, there is a page from the wiki.

For making an Linux installer accessible, there is a page from the wiki.
