  Hi agan!
   I missed one angle entirely: the GNOME desktop has a few helpers for
 the visually impaired. Magnifiers and orca (mixed results for braille
 display or speech) are there to assist and the GTK itself has a few
 good hooks for those things. I believe they thought about it quite a
 while. So GTK-based software, at least some of it, could probably
 called "software for visually impaired people" as well.
   Kindest regards

thanks.
