[Blindmath] Using Java Draw2D in an SWT GUI

True forcing them might not be possible but there are many examples of small
software companies that once shown the problem quickly fix their
accessibility if the tools are good enough to make it easy.  Take  IOS Coco
for example.  When I first got my IPhone I was looking for  main stream
games that I could play.  My wife was playing a game called Moxi so I tried
it out since it was just letters.  It turns out the coder didn't use the
accessibility information so it was unplayable.  I wrote the coder and he
wrote me and told me he didn't have time to fix it because he was working on
moxi II.  He  wrote me a week later and said both Moxi II and Moxi were now
accessible.   That is just one small company I have seen do that but the
point is you are correct the tools need to be easy enough and there needs to
be documents that easily show developers what they need to do like the Apple
accessibility documents that I sent to the Moxi coder.

I am hoping the same is true for this next generation of Android and Windows
Android has already improved their accessibility at least by double with the
new accessibility event nodes and hopefully Windows is as good as it is
supposed to be when windows 8 comes out.  The more main stream applications
that can be simply made accessible the less there is for us to do.  Even
with your document example that would only take an accessibility company
taking the document and labeling it so while you don't do it the
accessibility is there because of the tags even if it is a sad way to do
access.  I just go back to the day when it took me 6 minutes to scan a
document and I had no access to the graphs or pictures.  The access of
information is looking up I just try to look at the good side and things are
getting better as long as we continue to push the development tools.

While it may be possible to force the large corporations to adhere to
accessibility standards through threatened legal action, a large portion of
the really useful software these days is developed and provided for free
(or for a nominal charge) by independent programmers like myself who
develop the software and give it away for free. Threaten these developers
with legal action, and they will simply stop giving away good software.

It is probably unrealistic to believe that anyone can create software
development tools that will force independent software developers to
produce accessible apps. Take for example, the DTD for XHTML 1.0
Transitional. To be valid, an XHTML document must provide an "alt" field
for every image. However, there is no way to require the author of the
document to make the contents of the field meaningful. The easiest thing to
do is to simply enter an empty string in the field. In other words, hit
quote quote Enter on the alt field and the requirement is satisfied. I
myself am guilty of having entered the string "Missing image" -- probably
thousands of times given the number of documents containing images that I
have published. While that satisfies the requirement, and is a little
better than an empty string, it does little for accessibility.

And by the way, let's not forget that largely inaccessible software is
still being sold or provided for free within the blind community by
companies whose existence depends on the blind community.

While I don't have an answer to the problem of inaccessible software, it is
clear that at least two factors will be required to cause a large
percentage of software that is provided by independent developers to be
accessible:

1. Persuasion
2. Ease of development

Persuasion - Independent developers of the sort who populate SourceForge
with free software and who sell cheap apps on the iPhone and Android
platforms aren't likely to be influenced in a positive way by threatened
legal action. Those developers are more likely to be influenced through
persuasion. Again, threaten them and they will simply find other ways to
spend their time.

Ease of development - Before there will be any large-scale migration toward
accessibility among independent developers, tools that create accessible
software must be no more difficult to use and must require no more time and
effort to use than the alternative tools that don't produce accessible
software.

There are many very capable blind programmers in the world. Perhaps those
programmers should devote their efforts to the development of tools that
will cause sighted independent programmers to be happy to make their free
software accessible. At this point in history, such software doesn't exist,
at least not in the Java world with which I am most familiar.
