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
Julien
