Last week I was attending the CSUN conference - probably the biggest and most exciting Accessibility conference in the world.
The different presentations made it clear: Web Accessibility, ARIA and AJAX are still very hot topics.
For Windows Accessibility, IAccessible2 is still making a lot of progress. Some Screen Readers already have support for it, and I hope we will have it in OpenOffice.org soon.
I gave a small talk in an IAccessible2 session, my presentation can be found here.
Of course I have used the cool PDF export in OpenOffice.org, which allows you to create well accessible, tagged PDF. Unfortunately, creating tagged PDF is not the default, because of the increased file size. I hope we will change the default eventually. For now, use the "Export as PDF..." menu item in the file menu, which will give you a dialog where you can check the option to create tagged PDF. The tool bar item skips this dialog.
In parallel to IAccessible2 on Windows, we are also working on support for the Mac OS X Accessibility Framework!
We have shown the latest builds to some AT vendors, and it seems they are very exited about this. From what I heard, not many applications on Mac OS X have good support for this right now.
So with all our Accessibility work going on, I am very confident that OpenOffice.org 3.x will be very accessible on many different platforms, with native support for the platform specific Accessibility frameworks!
