Nonsense. There is no reason why the usage of Captcha's would
need to present accessibility problems.
No offense, but please look into it.
You are welcome to explain, rather then just assert, what is
inherent about the concept of a Captcha that would force
accessibility problems upon a website.
Read your own reference:
http://en.wikipedia.org/wiki/Captcha
That says:
Accessibility
See also: Web accessibility
Because CAPTCHAs rely on visual perception, users unable to view a
CAPTCHA (for example, due to a disability or because it is difficult
to read) will be unable to perform the task protected by a CAPTCHA.
As such, sites implementing CAPTCHAs may provide an audio version of
the CAPTCHA in addition to the visual method. The official CAPTCHA
site recommends providing an audio CAPTCHA for accessibility reasons.
Why should I have to explain something that is widely known and easy
to find?
So, I'm curious, what prevents a website from providing a good
implementation of both an audio and visual captcha to prevent
accessibility problems which you claim are impossible to avoid with
every use of a captcha?
Personally, my favorite implementation to date is:
http://recaptcha.net/learnmore.html
and not only is it well designed, but all that brain power which goes
into solving captcha's goes into helping out with a very worthwhile
project.
Remember, the concept of a captcha is this:
A test to prove one is human in order perform some action.
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.
