Mike,

This sounds like great explanatory information or techniques but I believe
the subcommittee view is that such requirements are too prescriptive to be
part of the provision itself.

We have been talking about starting to gather this kind of information to
be delivered to the Access Board as a supplement to the provisions. I
haven't set anything up for that yet but plan to set it up soon. Please
hold on to this idea so we can be sure to capture it when I get things set
up.

I have been away for a while so if this question has been addressed
please excuse the intrusion. Has there been any consideration for the
size, shape or blink rate of the focus cursor? This is very important
in using terminal emulation software as the assistive technology must
find the cursor first and the blink rates and size are a factor. The
size and blink rates also affect screen magnification users, as the
speed can be very distracting. Typically, the applications have an
ability to change the characteristics of the cursor, but the AT still
has to be usable with it. Thanks.

Okay, it looks like we have reached consensus on this as the final
wording now with the existing and modified notes:

"Any keyboard operable user interface must have a mode of operation
where the indication of keyboard focus has a high degree of visibility.
This can be provided by the interface itself or by the interface in
combination with focus services provided by the platform."

- NOTE: If the object is a text entry field, a visual indication of the
text insertion point is sufficient as a focus cursor.

- NOTE: A focus cursor that is visually locatable by people (familiar
with what the focus cursor would look like) who have 20/20 vision at
3.5 times the typical viewing distance without moving the cursor is
sufficient.

- NOTE: Since computer software would be displayed on unknown screen
sizes: for computer software a focus cursor that is visually locatable
by people (familiar with the cursor) who have 20/20 vision at 2.5 meters
when software is displayed on a 38 cm (15 inch) diagonal screen at 1024
x 768 pixels resolution, without moving the cursor is sufficient.

Objections only please.
