I am pretty sure they are talking about the application being usable by people who might be impaired in some way: https://en.m.wikipedia.org/wiki/Computer_accessibility

I "think" having options to make font and controls more legible, and being accessible by a screen reader(which you GUI framework should facilitate), is 85% done.

search HN for blind or accessibility, I suspect you will find great resources.
