Re: Use of role="application" for flash files

I guess I don't quite understand your concern. You own your own plug-in for
flash. As long as your tools allow ARIA semantics to be used you would map
it to the designated API in your player.

Sorry for my confusion. My mind may be numbed by the Obama
inauguration. :-)

First, I agree with Rich that role="application" makes sense for Flash
objects right now.

However, I can envision a point in the future where Flash Player could
itself implement ARIA. The Flex framework in particular would benefit from
ARIA role and state, as well as live regions. We already have similar
functionality in ActionScript 3. But we will need to add support for IA2 or
UIA to take that next step. My big concern here is leading UA implementers
down a path today that will keep us from doing our own ARIA implementation
in the future. What happens then? Has there already been a discussion about
ARIA-aware plugin content?

The AT should not ignore landmarks in "document browsing" mode so for this
it should not matter if you are in "application" mode. Flash supports
platform accessibility APIs in the form of MSAA. What they do not do at
this point is support a richer accessibility API which would support the
entirety of WAI-ARIA. I believe Adobe is looking at the end to end solution
but I don't know what progress they have made to supporting an extended API
set like UIA or IAccessible2 in the flash player. Matt May can speak more
to this.

My experience with Flash is that when it is accessible it works when you
are doing application mode style navigation. Browsing the virtual buffer
did not work so well. So, I would agree that having role="application"
would be a great addition to Flash.

Matt, what are your thoughts?

I can see the benefit of using application on a Flash movie for the
sake of landmark navigation, but it also is intended to communicate to
the UA/AT to switch from 'document browsing' mode into 'application
interface' mode, so it doesn't make as much sense b/c Flash movies
aren't ARIA applications. In a sense, because Flash isn't accessible
on all systems, and because the interface is very different from the
web browser's interface, the author is promising the user something
they can't always deliver, or may not deliver in the way the user
expects.

In theory, on the platforms where Flash is accessible, the Flash
player could/should communicate role, state, and property information
directly to the accessibility API, instead of going through the
browser via ARIA.
