As it stands CAPCHA is problematic for any users with disabilities...Thanks for the link. Boone, this is an interesting proposal.

Genius.  Thanks for sharing this example of innovative thinking.

According to Wikipedia, the “P” in the acronym comes from “Public”:
Completely Automated Public Turing test to tell Computers and Humans Apart.

CAPTCHAs based solely on reading text — or other visual-perception tasks — prevent visually impaired users from accessing the protected resource. Such CAPTCHAs may make a site incompatible with Section 508 in the United States. Any implementation of a CAPTCHA should allow blind users to get around the barrier, for example, by permitting users to opt for an audio or sound CAPTCHA.</blockquote> <br /><br />The key to CAPTCHAs is that they must be automatically generated and nearly impossible to crack with a program.  This creates impediments for the visually impaired user... a potential work around to give that person access is for the site to include contact information to manually arrange access. Good question.    

From the CAPTCHA website, section on “Guidelines” for use:

Accessibility. CAPTCHAs must be accessible. CAPTCHAs based solely on reading text — or other visual-perception tasks — prevent visually impaired users from accessing the protected resource. Such CAPTCHAs may make a site incompatible with Section 508 in the United States.

The key to CAPTCHAs is that they must be automatically generated and nearly impossible to crack with a program.  This creates impediments for the visually impaired user… a potential work around to give that person access is for the site to include contact information to manually arrange access.

But do you know how this will work for blind users using assisstive technology? What if someone is using Jaws or similar speech recognition software to read everything that is on their screen: will the computer read the Captcha? Interesting indeed.
