It is a bit confusing but what I was saying is
- built-in means that a capability is in the product when sold.
- compatible with AT means that it will work with AT that a user (person or
agency) adds later
With a kiosk, which is closed, the user can't add or install AT. That is
the definition of closed essentially. In order to be accessible the access
would need to be built in. A company could use many different methods to
do this. One of them might be to include a screen reader (that was easy to
use for most people who were blind who would encounter the kiosk) as part of
the software in the kiosk.
The kiosk would thus be both closed and accessible because of the built-in
Another kiosk that was AT compatible but did not include any screen reading
capability and was closed would not pass since there would be no way for
anyone with a disability (of this type) to use it.
This example is of course just covering one dimension of access. There are
other disabilities and even other issues for blindness (like tactilely
discernable controls for the screen reading feature).
Does this help?
