W3C on inaccessibility of CAPTCHAs

Nice to see an “official” response to CAPTCHAs (”completely automated public Turing test to tell computers and humans apart”):

The WAI Protocols and Formats Working Group has released Inaccessibility of CAPTCHA: Alternatives to Visual Turing Tests on the Web as a Working Group Note. Requests for visual verification of a bitmapped image pose problems for those who are blind, have low vision or have a learning disability such as dyslexia. The note examines ways for systems to test for human users while preserving access for users with disabilities.
