How to make applications accessible?

Because “One person out of ten consider having a handicap, but one person out of five consider being limited it her activitie”, “15% of the world's population lives with some form of disability”, Laws require accessibility.

Or rather, how to make accessible applications? This section gathers links to documentation and videos talking about it. The idea is that ideally you should not have to focus on accessibility features, but just integrate in your development process good practices which improve accessibility: in a couple of words, simple and logical design, instead of complex and graphical design, and configurability.

Accessibility Howto

There is a guide. It is a bit old, but it still gives a good idea of the needs.

Gnome has its own guide.

KDE has its own guide.

Qt5 has a guide for QWidget and a guide for Qt Quick.

There is also a good LinuxJournal article.

So as to check how good your graphical application looks like, you can try Accerciser.

There is guide for text applications for testing accessibility of text applications.

For GULs, there is a page from the wiki.

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

BrlAPI

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:

Linux

A set of fonts/keyboard mappings for typing braille on the linux (>= 2.6.17rc1) console with regular keyboard.

Braille tables

You can find here some braille tables which don't seem to be supported by nowadays' screen readers.

Brltty for Windows and DOS

You can get some old Windows and DOS version of brltty here.

Free Braille Displays

Braille devices are expensive and non free, please join us on the Free Braille Display project.
