Dear WAI Interest Group Participants: On 5 November 2003 the W3C/WAI Protocols and Formats Working Group (PFWG) published a Working Draft of a paper addressing accessibility problems with visual Turing tests, also known as CAPTCHAs. These tests, which involve visual verification of a bitmapped image, are increasingly being used to limit access to services made available over the Web. They present a major problem to users who are blind, have low vision, or have a learning disability such as dyslexia. This Working Draft examines a number of potential solutions that allow systems to test for human users while preserving access by users with disabilities. Inacessibility of Visually-Oriented Anti-Robot Tests: Problems and Alternatives http://www.w3.org/TR/turingtest/ Comments are welcome at the publicly archived mailing list wai-xtech@w3.org.
