I would like to consider if we are speaking specifically about
*requires physical contact for normal operation* or is it simply
*physical controls that affect the operation of the product*?
Playing devil's advocate, if I create a control for a product
that I deem isn't a part of *normal operation* then do I get a
get-out-of-508-free card? If I create physical controls that doesn't
require physical contact, because I have software that can remotely
control the product (e.g., software that controls the copier, email,
fax, all-in-one printer on my desktop connected to the LAN) and even
more importantly to my point are *not* accessible without previously
mentioned software, is that acceptable?
I'd really like to see something that doesn't fail when combined with
or without accessibility. The terms "required" and "normal operation"
are tied to the accessibility discussion. My point: you have operable
controls but we shouldn't assume they are accessible.
Suggested definition: "Operable controls: any physical control
that affects the operation of the product. Operable controls include,
but are not limited to, mechanically operated controls, input and output
trays, card slots, keyboards, keypads, keys, or buttons, including
touch-screens." Note I added individual keys and buttons, as I've
inspected many devices that have only those features where the
manufacture thought Section 508 didn't apply because it didn't have "a
Just my two cents.
