A few weeks ago in A Coruña, Spain a Hackfest around GNOME Accesibility took place hosted by Igalia . openSUSE found the opportunity to make some questions to the people involved and then learn a bit more about this interesting Project.
Most assistive technology software is not cross platform because it is often closely integrated with the operating system and screen display sub-systems. Commercial developers also face the challenge that the potential user base is not large, so prices can be high, which restricts the user base even more.
I used the Assistive Technologies on screen keyboard because hotplug was not working and I could only use my bluetooth mouse. Now, even after disabling Assistive Technologies, the icon still appears in the apps toolbar, next to my network connection status icon and battery status icon, also next to the clock and date.
Orca, a free, open source, flexible, and extensible screen reader that provides access to the graphical desktop via speech and refreshable Braille, is now at version 3.10. Orca works with applications and toolkits that support the Assistive Technology Service Provider Interface (AT-SPI), which is the primary assistive technology infrastructure for Linux and Solaris.
