'''GNU Accessibility Statement'''
 
 
 
[http://www.gnu.org| Project GNU] urges people working on free
 
software to follow standards and guidelines for universal
 
accessibility on GNU/Linux and other free operating systems.
 
Multi-platform projects should use the cross platform accessibility
 
interfaces available that include GNU/Linux distributions and the
 
GNOME desktop.  Project GNU also advises developers of web sites to
 
follow the guidelines set forth by the World Wide Web Consortium's Web
 
Accessibility Initiative.

According to the United Nations in 2005, there were 600 million
 
people with disabilities in the world.  To use computers, many of them
 
need special software known as &ldquo;access technology&rdquo;.  Like
 
other programs, these can be free software or proprietary.  Those
 
which are free software respect the freedom of their users; the rest,
 
proprietary programs, subject those users to the power of the
 
program's owner.
 
 
In order for access technology to work, the other software in use
 
must interoperate with it.  The majority of computer programs and web
 
sites (85% in one estimate) do not comply with accessibility standards
 
and guidelines, so they do not work with access technology.  They
 
provide a frustrating experience, and can bar users from job or school
 
activities.
 
 
Proprietary file formats that require proprietary reading programs
 
are poison to both accessibility and to the freedoms that we as free
 
software activists hope to establish.  The biggest offender is Flash
 
format; it usually requires proprietary software that doesn't
 
cooperate with accessibility.  Microsoft Silverlight is similar.
 
<acronym title="Portable Document Format">PDF</acronym> is also
 
difficult; though there is free software to view it, it does not
 
support free access technology software.  GNU PDF aims to do
 
better.
 
 
People with disabilities deserve to have control of their own
 
technological destinies.  When they use proprietary access technology,
 
they have little or no way to correct whatever is wrong with it.
 
Virtually all major decisions of the proprietary developers are made
 
by people who do not have the disability; 20 years' experience shows
 
that people with unusual combinations of disabilities, who require
 
relatively unusual software, or who encounter a bug that keeps them
 
from doing their job have no way to obtain the changes they need.
 
These products are only changed or improved when the vendors see a
 
business reason for doing the work; this leaves many users behind.  As
 
a secondary problem, proprietary access software is far more expensive
 
than a PC.  Many users cannot afford to give up their freedom in this
 
way.
 
 
For users with disabilities, as for all other users, free software
 
is the only way the users can control their own computing, their only
 
chance to make software fit their needs rather than passively
 
accepting whatever developers choose to offer them.
 
 
Nations with large populations also have large numbers of people
 
with disabilities.  Countries including Brazil and Russia are
 
discussing whether to standardize government purchases on GNU/Linux
 
platforms.  These nations are all signatories to the UN Convention on
 
Human Rights and People With Disabilities, and include technology in
 
their agenda for providing such rights.  This will require them to
 
hire programmers to work on accessibility software for their
 
populations.  If it is free software, the rest of the world will be
 
able to use it too.  The hackers who work on free access technology
 
will provide tools that people with disabilities can use to expand
 
their horizons enormously.
 
 
Ensuring that your application or web site is accessible is the
 
right thing to do.  And it fits naturally with free software.
 
 
'''Recommendations'''
 
 
Application software developers should learn how to use the
 
accessibility features of the <acronym title="Integrated Development
 
Environment">IDE</acronym> or toolkit they employ to build their user
 
interface.  Programmers who need to implement access technology, or
 
work on a desktop or OS-level accessibility problem, will need to
 
understand the accessibility <acronym title="Application Programming
 
Interface">API</acronym>, and should choose the one that is compatible
 
with free OS/desktops.  These include the [http://library.gnome.org/devel/accessibility-devel-guide/stable/index.html.en| GNOME accessibility API]
 
(GNU/Linux platforms only), the [http://java.sun.com/javase/technologies/accessibility/docs/jaccess-1.3/doc/core-api.html| Java accessibility API] (GNU/Linux and
 
Windows) and [http://www.linuxfoundation.org/collaborate/workgroups/accessibility/iaccessible2| iAccessible2] (GNU/Linux and Windows).
 
 
<ul>
 
  <li>Web developers should follow the [http://www.w3c.org/wai| W3C web accessibility guidelines]
 
and, for complex web applications, the developers should follow the [http://www.w3.org/WAI/intro/aria| Accessible Rich

<li>[http://www.gnu.org/philosophy/javascript-trap.html| Nontrivial Javascript code distributed to the user]
