Initial comments from the SSA Accessibility Staff on the recommended
1194.21 provisions shared at the last TEITAC meeting.
1194.21a (minor edit for clarity)
All functionality of the user interface is operable through a keyboard
interface. Specific timings for individual keystrokes cannot be
required, except where the underlying function requires input that
depends on the path of the user's movement and not just the endpoints.
Consider specifying an acceptable contrast ratio and set a minimal pixel
size for the border to improve testability.
How would an application vendor handle coding for multiple platforms?
Consider exposing page name and page section (heading tag and associate
different sections of a page)
Consider exposing field association directions and cues
Consider deleting "when the availability of those selections are
developed and documented according to industry standards" . We don't
see the need for qualifying it-that confuses it. The systems colors and
fonts should always be an option, and they should always be user
Consider adding "Information provided in the animation should be
included (alt text, long description, or on screen)"
Consider deleting the specific reference to equivalent facilitation
here. Equivalent facilitation should not be encouraged as a way of
meeting a standard explicitly in the standard itself.
Consider specifying "n"
Consider specifying what is needed for access to directions and cues -
these have not been raised as a concern. Should this be an expansion of
other requirements - such as 1194.21(d), rather than making it specific
to electronic forms here?
Consider adding a provision for logical tabbing order. SSA runs across
many applications that do not provide a logical tabbing order, creating
situations where we could have "30 keystrokes to one mouse click".
Consider adding a provision for minimal size for clickable elements
including clickable text. (low vision users)
