Ken, I couldn't agree more. If this could be done in a manner that uses a technique that does not need the bridge, it would be a huge win.
Someone (name omitted for privacy reasons) is likely to donate a bridge-free screen access tool for Java to the FSF/GNU. We'll give it a repository and someone can volunteer to be its maintainer and, from there, the community will be in charge of our own destiny regarding Java accessibility.
We're only waiting on some code clean-up which, I'm told, won't take too long, then we need to put on a free software license and the world can get to work on this highly innovative approach to Java accessibility.
** I have no clue whatsoever when this task will be completed to the point that it is part of the world of GNU and make no promises nor assertions or even guesses at when it will become available. **
People interested in getting involved in this or any other GNU accessibility project should first join our very low traffic accessibility discussion mailing list by sending an email to accessibility-requests@xxxxxxx with "subscribe" (sans quotes) in the subject line. We have lots of projects that need help immediately and others in the early planning stages. We need help with coding, testing, documentation, tutorial and nearly every other software related task on a bunch of interesting accessibility initiatives.
As for the mailing list, it is for discussing all aspects of free access technology software so everyone is welcome. If the list grows and becomes too high volume, we'll probably add an accessibility hackers mailing list for the highly technical. The only topics that are banned from the FSF/GNU accessibility mailing list are debates of the relative merits of proprietary versus free software licenses - we are, after all, the Free Software Foundation and we're not likely to change our values for any reason whatsoever.

It is sad but the truth is the only way we are going to truly get universal access to Java is if someone sits down and writes a java screen reader / tool kit that makes the entire system talk. This would be cross platform and injected into the Jvm like the access bridge. Otherwise we end up writing scripts for jaws, Plug ins for window - eyes, other methods for other screen readers and we are all working on multiple methods. If we all worked on one method it would be done in a year to the point of at least something like voice over. ken -----Original Message----- From: programmingblind-bounce@xxxxxxxxxxxxx [mailto:programmingblind-bounce@xxxxxxxxxxxxx] On Behalf Of Jamal Mazrui Sent: Saturday, June 12, 2010 2:45 PM To: program-l@xxxxxxxxxxxxx Cc: programmingblind@xxxxxxxxxxxxx; Roopakshi Pathania Subject: Re: [program-l] Re: Developing cross-platform, accessible apps Correction -- Window-Eyes does not have native support for the Java access API, but considerable support has been developed by a third-party script writer. A significant problem, however, is that there is little tech support for that script at this time.

This is more the fault of the screen reader companies than Sun, since the API is strong on the server side. Window-Eyes, for example, does not support that API at all. JAWS works partially. I hear that NVDA works well. I do not know about System Access or Hal. With the SWT approach, on the other hand, apps can be fully accessible because native widgets are used, including MSAA-integrated controls on Windows. Thanks for the info about Axtk, which I had not heard about. At first, I thought the name was associated with the cross-platform GUI library called TK, which has poor accessibility, but I see that it is actually wx-related, as you say.

In this regard, the guidelines laid down by IBM on developing a completely accessible Java application are quite useful. http://www-03.ibm.com/able/guidelines/software/accesssoftware.html I like to point the developers of inaccessible applications to this page. One more toolkit might be of interest: AxTk. http://code.google.com/p/axtk/ It is built on wxWidgets and is especially geared towards screen reader users. It is also suppose to have text to speech wrapper class supporting a number of speech engines. I’m building my own tools for financial and data analysis, so have looked at cross-platform accessible libraries.

Currently, the key is using programming libraries that wrap native widgets of the platform. These native widgets generally implement the main accessibility API of the platform, much more so than custom widgets. On Windows, native widgets are most likely to implement Microsoft Active Accessibility, or increasingly, User Interface Automation as it replaces MSAA. On Linux, the GTK+ widgets that are native to the Gnome desktop implement the Assistive Technology Service Provider Interface. On the Mac, Cocoa-based widgets implement the Mac Accessibility Protocol. Thus, a cross-platform library is most likely to create accessible GUIs if it wraps native widgets of each platform, rather than defining its own widgets. A disadvantage of this approach is that the developer needs to be conscious of small differences in the behavior of widgets across platforms, even though wrapping code of the library tries to minimize such differences. Besides accessibility, an advantage of this approach is that widgets have the look and feel that sighted users are accustomed to experiencing on each platform. Sometimes, a GUI library is closely associated with a programming language that has especially strong support for that library in wrapper functions and design tools. A few language and library combinations that seem to work particularly well for cross-platform, accessible development are as follows: * Java and the Standard Widget Toolkit http://www.eclipse.org/swt/ * Python and wxWidgets http://wxPython.org * C# and the System.Windows.Forms classes of the Mono Framework http://mono-project.org Note that, in this case, the Microsoft .NET Framework should be used as the runtime environment on Windows in order to have native widget support. http://msdn.microsoft.com/en-us/netframework/default.aspx If others have further info or ideas on this topic, please share.
