Regards, Loretta Guarino Reid, WCAG WG Co-Chair Gregg Vanderheiden, WCAG WG Co-Chair Michael Cooper, WCAG WG Staff Contact On behalf of the WCAG Working Group ---------------------------------------------------------- Comment 1: simplify "alternate forms in different modalities are provided" Source: http://lists.w3.org/Archives/Public/public-comments-wcag20/2007May/0129.html (Issue ID: 1931) ---------------------------- Original Comment: ---------------------------- I would be grateful if you could simplify the following as found in Web Content Accessibility Guidelines 2.0 (WCAG 2.0) Principle 1, Guideline 1.1 1.1.1 Non-text content, 3rd point CAPTCHA Text reads "....alternate forms in different modalities are provided...." Could you simplify this by being a bit more verbose... ...different modalities? Do you mean using different methods or technologies to provide the content to accomodate different disabilities, if so, say so. There may also be a technical issue here in that providing those different methods of representing the content may compromise the security of using CAPTCHA in the first place and so render it useless. Thinking like a miscreant, if I can exploit an accessibility method used to represent this content to bypass the security of that content, then I probably will. --------------------------------------------- Response from Working Group: --------------------------------------------- We have adopted your recommendation in the Success Criteria as follows: "If it is to confirm that content is being accessed by a person rather than a computer, then text alternatives that identify and describe the purpose of the non-text content are provided, and alternative forms of CAPTCHA using output modes for different types of sensory perception are provided to accommodate different disabilities." Regarding the security issues of requiring different forms of CAPTCHA, we spent a lot of time considering the pros and cons of allowing CAPTCHA. We believe that in today's environment it is necessary to encourage accessible CAPTCHA, and we think requiring different forms is the best way to approach the accommodation of people with varying disabilities.
