There are many people in the world who cannot make full use of their
computers without some sort of accessibility support. Developers, though,
have a tendency not to think about accessibility issues themselves; they
don’t (usually) need those features and cannot normally even see them. In
a talk at the 2020
GUADEC virtual conference, Emmanuele Bassi discussed the need for
accessibility features, their history in GNOME, and his effort to rethink
about how GNOME supports assistive technology.
