There is no documentation anywhere which claims, as you do, that it is
impossible to design a captcha which deals with accessibility issues.
a lack of evidence proving the impossible ... there is a logic flaw
there somewhere.
It
has been done and the research into doing it better continues - even
with those who are both blind and deaf.
So, again, remember, the concept of a captcha is this:
A test to prove one is human in order perform some action.
so orthogonal to the turing test ... I'd wager that research in
turing test passing technology is moving faster that captcha tech.
so in the long run captcha is plain dead in the water.
really the basic concept of captcha is this:
A test to prove that the interacting agent is legitimate,
whether it be Bot, Cat, Human or otherwise.
oh, and nobody's yet mentioned that anyone can bust any captcha
on an automated scale without any programming intelligence, it
takes nothing more than a setting up a pr0n affliate site with
a redirector form that sneakily grabs captcha images from whatever
the target of the day is ... and in such a case you'd be quite happy
if someone's bot came along a repeated cracked "your" captcha
There is no reason why a blind or deaf person absolutely cannot be
presented with such a test. Now, if you wish to continue to argue to the
contrary, you are more then welcome to do so.
