Accessibility stack internals
For graphical desktop accessibility to work, three things are needed:
- the accessibility bus get started,
- toolkits load their accessibility layer,
- a screen reader get started.
The first two points, described in details below, can be checked automatically on any desktop with
$ git clone git://git.debian.org/git/pkg-a11y/check-a11y $ sudo apt-get install build-essential pkg-config libdbus-1-dev libatspi2.0-dev libgtk2.0-dev libgtk-3-dev libqt4-dev qtbase5-dev $ cd check-a11y $ source env.sh $ make check
Accessibility bus getting started
This is provided by package at-spi2-core.
For gnome and Unity, this is automatically started from /etc/xdg/autostart/at-spi-dbus-bus.desktop under condition:
gsettings get org.gnome.desktop.interface toolkit-accessibility
For MATE, this is automatically started under condition
gsettings get org.mate.interface accessibility
Others don't start it automatically, but it is getting started when running accessible GTK2, GTK3 or QT4 applications with accessibility enabled. QT5 doesn't start it automatically, but can catch up with it afterwards if accessibility is enabled in it, see below.
Toolkits loading their accessibility layer
gtk3 needs libatk-adaptor and libgail-common, no condition.
gtk2 needs libatk-adaptor and libgail-common, loaded when GTK_MODULES=gail:atk-bridge or loaded by /usr/lib/gnome-settings-daemon-3.0/gtk-modules/at-spi2-atk.desktop when gnome-settings-daemon is running and gsettings get org.gnome.desktop.interface toolkit-accessibility is true.
KDE4 needs qt-at-spi, conditionalized by QT_ACCESSIBILITY=1
KDE5 has it integrated, conditionalized by
gsettings get org.gnome.desktop.a11y.applications screen-reader-enabled
but starting from QT5.4, it can also be forced with QT_LINUX_ACCESSIBILITY_ALWAYS_ON=1
java needs libatk-wrapper-java, conditionalized in /etc/java-7-openjdk/accessibility.properties :
assistive_technologies=org.GNOME.Accessibility.AtkWrapper
TODO: mono ?
screen reader getting started
Part of Debian Installer testing: DebianInstaller/Accessibility
Under Gnome3, MATE, Unity, Cinnamon, started by /etc/xdg/autostart/orca-autostart.desktop under condition
gsettings get org.gnome.desktop.a11y.applications screen-reader-enabled
- Gnome2: started under condition
gconftool-2 --get /desktop/gnome/applications/at/screen_reader_enabled
- XFCE could have it
xfconf-query -c xfce4-session -p StartAssistiveTechnologies
- KDE: started under condition
qdbus org.kde.kaccessibleapp /Adaptor setSpeechEnabled true
- LXDE?
Notes about packaging
- pkg-a11y project on alioth, we usually use git repositories.
- speakup: speakup_decpc is not free, that's why we use a dfsg branch. To release a newer upstream version, pull the upstream branch from the dfsg branch, then pull the dfsg branch from the debian branch, then run git-buildpackage --git-tag --git-upstream-branch=dfsg
- liblouis*: import tarballs to the upstream-import branch (git-import-orig file.tar.gz --upstream-branch=upstream-import), then pull into the upstream branch and discard the conflicts in generated files which we do not ship in the .orig.tar.gz

Packaging
Package nfbtrans, see http://lists.debian.org/debian-accessibility/2008/05/msg00043.html http://www.nfb.org/nfb/nfbtrans.asp
- Hook braille translators into cups
Package Anumaan http://www.cdacmumbai.in/index.php/cdacmumbai/research_and_publications/research_groups/open_source_soft_division/projects/anumaan
- Package eviacam (Cesar Mauri is working on it)
- Add a tasksel element. It doesn't seem so simple, we'd need subtasks. Maybe a complete package that asks precise questions.
- Help Mario with the packages he requested help for.
- See how to write a win32-loader frontend to easily configure a11y parameters
See mono's UI Automation/ATK accessibility bridge http://www.mono-project.com/Accessibility
GEM http://www.cdacmumbai.in/ http://www.cdacmumbai.in/projects/accessibility/
lios http://sourceforge.net/projects/lios/?source=navbar https://gitlab.com/Nalin-x-Linux/lios-3
- chewing-word, on alioth, licensing issue.
- petitboot, Bug#659668: ITP: petitboot -- A kexec based bootloader, integrate with brltty to make it an accessible bootloader. Or just wait for the grub version with integrated brltty.

brailleblaster http://www.brailleblaster.org/
marytts http://mary.dfki.de/
speechless https://github.com/raginggoblin/speechless
What is the status of this? the web page claims the repo is at https://googlecode.com/hg/ but that's an empty hg repo. Is developement happening somewhere else?
- odt2braille and odt2daisy, needs liblouisxml 2.3.0, or maybe libutdml is enough.
dae ftp://ftp.csir.co.za/MI/National_Accessibility_Portal/wvdwalt/dae-latest.tar.bz2
- magnifier magnifier.sourceforge.net (was waiting for lazarus 0.9.29, now available)
?OpenMary (http://mary.dfki.de/ , svn checkout https://mary.opendfki.de/repos/trunk)
?VoxForge http://voxforge.org/
- Enable libjs support in links2
afaik a11y support for mono is packaged, is there more to package / update or is testing still needed for this?
Installation
More generic details on http://brl.thefreecat.org/wiki/Installer
- Tune accessibility support in the liveCD.
- Add brltty/speakup parameters preseed support?
- Create a webpage that generates preseed files according to the hardware selected by the user in a form.
- Another way is putting parameters in the iso itself:
- Add AT-SPI and Orca/gok to debian installer
- speakup translations should be loaded automatically according to installation locale, at least
desktop qualification: DebianDesktop/Requalification/Jessie
Documentation
Add an accessibility section to http://wiki.debian.org/Derivatives/Guidelines and tell debian-derivatives@lists.debian.org about it.
- Add an accessibility chapter to the developer's reference
- Add accessibility questions to the NM process.
- Add an "Accessible Event Howto".
Misc
- Add package tags: something like accessible-with::{at-spi,tty-screen-reader}, accessible-with::{braille,speech}, accessible-with::{gnome-orca,brltty,speakup}
- Add an accessibility tag to bugs (and thus cc-ed to debian-accessibility)
- Make accessibility bugs RC, or at least consider them with care during freeze?
- Add archive Accessibility section?
Rasterize console fonts (595696). Useful for both bigger and smaller fonts
Use personas: [http://www.aegis-project.eu/index.php?option=com_content&view=article&id=63&Itemid=53], [http://www.w3.org/WAI/redesign/personas]
