RE: Background audio (was: Impact of not setting baseline and writing SC as functional outcomes)

Hi all,
 
John, I understand the need for an explanation but isn't that why we have a
'who benefits' section? I think our success criteria should be as concise as
possible and not contain any explanations or rationale.
 
I would like to go with Mike's suggestion:<proposed>"A mechanism is
available to turn off background audio that plays automatically.</proposed> 

and add the following to 'who benefits':
<proposed>
People who are blind or have low vision can use a screenreader without
having the background audio interfere.
People who have learning disabilities may find it easier to concentrate on
the content without background audio.
</proposed>
 
A real-world example example of a site that has this problem:
http://www.stichtingmeerzicht.nl/
This is a Dutch website of an organization that focuses on participation of
people with a visual impairment in the 'normal' society. However, their own
website does not follow the WCAG. On mouse over, the navigation buttons are
read aloud. In my browser, this is all scrambled and just goes on and on
until you mouse-out.

Mike, I know it would be nice to get rid of the "so as" clause. But Gregg
made the point that this is one case where the rationale isn't necessarily
self-explanatory so that it might be worth keeping, and I think Becky's
proposed rewrite is good because it provides some explanation without
limiting it to a particular disability.

great work going through all of the success criteria and submitting several
proposals to address the issue!  I have a modified proposal for GL 1.4 level
2 success criterion 3. 

<excerpt from john's post> 
GL 1.4 level 2 success criterion 3: Users can disable background audio that
plays automatically on a page so that it does not interfere with text
reading software they may be using 
Impacted: yes 
<proposed>"A mechanism is available to turn off background audio that plays
automatically. So that the audio does not interfere with text-reading
software that may be in use.</proposed> 
</john> 

<becky's proposed>"A mechanism is available to turn off background audio
that plays automatically so that the audio does not interfere with assistive
technology that may be in use. 
</becky's proposed> 
I would not assume that background audio only interferes with text reading
software.  It also might distract those with reading disabilities -although
they may not be using any assistive technology. Another, more generic
wording might be <proposal 2>"A mechanism is available to turn off
background audio that plays automatically so that the audio does not
interfere with the user's interaction with the remaining content."
</proposal 2>
