Description Laura Carlson 2010-02-28 12:17:10 UTC
It would be helpful to add a CAPTCHA example that is in accord with WCAG2 to "HTML5: Techniques for providing useful text alternatives":
http://dev.w3.org/html5/alt-techniques/

Current HTML5 Spec example:

<label>What does this image say?
<img src="captcha.cgi?id=8934" title="CAPTCHA">
<input type=text name=captcha></label>
(If you cannot see the image, you can use an <a
href="?audio">audio</a> test instead.)</p>

http://dev.w3.org/html5/spec/text-level-semantics.html#unknown-images

HTML Action 54 Example:
http://www.w3.org/html/wg/wiki/Action54AltAttribute#CAPTCHA_Images

WCAG 2.0 Technique G143 recommends, if a CAPTCHA test asks the user to type in text that is displayed in an obscured image, the text alternative is "Type the word in the image".

Thanks.

Status: Accepted
Change Description: have added a section on captcha images, note: the checkin schedule for the draft is not that regular for the moment, so may be a few days or so until it shows up in the draft.
Rationale: I had overlooked the captcha image case. Thanks for suggesting it.

Bug triage sub-team notes the task force has an interest in this but does not need to prioritize its work on these. Steve and the reporters can follow the usual process on these.
Comment 3 Laura Carlson 2011-01-01 21:42:24 UTC
Thanks for adding this, Steve.
