Re: Making A Better CAPTCHA For the Visually Impaired And Making Captions More Available To The Hearing Impaired

Samir:

I believe I understand why Lucy's experiencing some problems accessing your
audio content. There are some technical accessibility issues with your page
that need to be addressed first before you will get much out of user
testing. After just a few minutes, here are some starting points to fix
the page, things that I would consider must-have support features:


- *Perceivable:* I recommend some more browser testing if you want this
to be a popular alternative to CAPTCHA solutions in use today. Using
Windows, Firefox 20, the audio player does not visually display (screenshot
of page:http://i.imgur.com/Qef7IVL.png).

- *Operable:* The audio player is not keyboard accessible using Chrome
26, Firefox 20, or Internet Explorer 10. Some recommended reading on
keyboard accessibility, ARIA, and focus path (because I suspect that will
be the next hurdle for you):
-- Terrill Thompson's accessible audio player (just tested it again,
still working for me!): http://www.terrillthompson.com/music/aap/
-- ARIA best practices (and focus path management):
http://www.w3.org/TR/wai-aria-practices/

- *Understandable:* The label for the text entry is missing a FOR
attribute that will tie it to the input field's ID attribute. These two
elements must be associated programmatically in order for all users to
understand their relationship. For example, instead
of <label>Caption:</label>, you should have <label
for="responsenew">Caption:</label> where "responsenew" is the ID attribute
for the text input field.

- *Robust:* I think it would be beneficial if you did consider offering
multiple ways that users could access the audio content. Your suggestion
about an MP3 may be the answer. Either way, please ensure that your CAPTCHA
does not depend on a very specific combination of browsers, technologies,
or assistive technology to support it.


Again, that wasn't a full review or anything, but I figured it would help
to provide you some initial technical feedback before you run into any more
problems.


All the best,
Elle
