Hi, Scott:

I think our first step should be a consensus on what APA can recommend
to AGWG. I think we've covered the highlights already in this thread and
in our Conclusions section.

We should get something into a form we can run a CfC on.

And, just so you don't miss it, our paper has triggered a recent
Honeypot conversation on the WAI Interest Group list starting here:

http://lists.w3.org/Archives/Public/w3c-wai-ig/2019AprJun/0096.html

Now, participating in AGWG moving forward on our recommendations is
another matter entirely. I'm confident you'll be most welcome in that
process.

Best,

Janina

At the moment we have obscure implication suggesting that inference. I don't understand the need for indirection, except perhaps for the fact that the term itself is unfamiliar--as our document also acknowledges.

In so far as interaction is required, it should demand as little as possible of the user's sensory, cognitive, and manipulative abilities, consistently with meeting the security objective. The challenge here is that it's a matter of balancing the demands imposed on the user with what is needed to achieve a security goal; and there isn't a single "right answer" to this problem, as we acknowledge.

In the workshops I run I get asked about CAPTCHA a lot in terms of WCAG and if there is interest in supporting the workflows for a WCAG 2.2 or similar update I'd be happy to get involved if anyone could provide some guidance on how the workflows operate.
