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.

Regards,

Matt May, Team Contact for Protocols and Formats Working Group
Judy Brewer, WAI Domain Leader
