On last week's call we approved the version in the wiki and created
an action item (550) to update the document.
2.9.1 (former 4.9.1) Background Image Toggle: The user has the
global option to hide/show background images. (Level A)
Users can have difficulty reading text or recognizing images that
are shown against a non-plain background. Background images can also
be distracting.
Users can have difficulty reading text or recognizing images that
are shown against variable backgrounds. Background images can also
be distracting, especially to people with some cognitive
impairments.

impairments.
<kford> Possible Example, may be to fluffy.
<kford> John finds multiple images behind the text he is reading
distracting. He navigates to his favorite news site where he finds
today's weather displayed over a picture of a sunny sky with fluffy
clouds. He activates a button on a toolbar named "Hide Background"
and now can easily determine he's in for a day filled with sunshine.
A related resource: 1.1.1 Configure Default Rendering allows the
user to hide foreground images by replacing them with alternative
content, but 2.9.1 extends this to background images in languages
such as HTML that do not support alternative content for background
images.
<jeanne> Example: Sasha requires high contrast to be able to
discriminate the shape of letters. She always sets a preference in
her browser to turn off background images, so that she can see the
text clearly without the variations in the background.

<trackbot> Created ACTION-553 - Update document to include IER for
2.9.1 from the wiki. [on Jeanne F Spellman - due 2011-05-19].
2.9.2 (former 4.9.2) Time-Based Media Load-Only: The user can load
time-based media content @@ Editors' Note: DEFINE@@ such that the
first frame is displayed (if video), but the content is not played
until explicit user request. (Level A)
Users should be in control of side-effects of navigation, including
loading of new pages.This allows users to avoid distraction caused
by animations, and also allows deaf users to avoid disturbing people
around them by sound playing without their knowledge of permission.

interfering with the user's ability to hear their screen reader.
<jeanne> Users should control whether media plays automatically
particularly audio tracks that can interfere with assistive
technology, be a distraction to other users in the vicinity, or

photoepilepsy.

<trackbot> Created ACTION-554 - Add IER for 2.9.2 to document from
wiki. [on Jeanne F Spellman - due 2011-05-19].
<JAllan> Musicogenic epilepsy is a rare entity among the large
category of reflex epilepsies. Pure cases with no associated
spontaneous seizures are exceptional. Our observation confirmed the
implication of the right temporal lobe in this epilepsy.

2.9.3 (former 4.9.3) Execution Placeholder: The user can render a
placeholder instead of executable content that would normally be
contained within an on-screen area (e.g., Applet, Flash), until
explicit user request to execute. (Level A)
<JAllan> Mark, is working on his 2.9.6, 2.9.7, 2.9.8 will be putting
them in the wiki by next weeks meeting
Closely related is 2.9.4 (former 4.9.4) Execution Toggle: The user
can turn on/off the execution of executable content that would not
normally be contained within a particular area (e.g., Javascript).
(Level A)
2.9.2 should be limited to "recognized" time-based media.
2.9.2 would change to read "2.9.2 Time-Based Media Load-Only: The
user can load *recognized* time-based media content such that *a
placeholder* is displayed but the content is not played until
explicit user request. (Level A)
How about changing the title from "Time-Based Media Load-Only" to
"Placeholders for Time-Based Media" or the like?
Jeanne and Kelly want to keep the old title but use the new text.
<jeanne> ACTION: JS to update document with revised 2.9.2 text from
wiki. [recorded in
[11]http://www.w3.org/2011/05/12-ua-minutes.html#action03]
<trackbot> Created ACTION-555 - Update document with revised 2.9.2
text from wiki. [on Jeanne F Spellman - due 2011-05-19].
It seems to me that 2.9.2 and 2.9.3 should use parallel
construction, but it's not a major problem.
Discussion of whether 2.9.3 is needed. Jeanne suggests it's just a
subset of 2.9.2.
Greg said that 2.9.3 would apply to a Flash object that serves as a
button, which would not be considered time-based media. Jeanne asks
is there an accessibility need for blocking such objects, which are
not time-based.
Kelly says that if there's a plug-in without accessibility support,
the user would want to block it from running, for reasons different
from the time-based media issue.
Decided that the title of 2.9, Provide control content that may
reduce accessibility, is broad enough to include blocking
applets/objects that are inaccessible for reasons other than being
time-based media.
Is 2.9.3 just a specific case of the other SC that says the user can
choose to have alternative content rendered in place of the default
content?
Kelly says that IE9 has an example of this in a few feature called
"ActiveX Filtering", where you can disable ActiveX by default, but
enable it for specific pages.
In those cases fallback content is rendered in place of the ActiveX
object.
Jim feels a placeholder is needed, but Kelly feels that an indicator
would be enough.
Kelly suggests that displaying fallback content that the author
provided for use when the applet/technology is not supported would
be just as good or better than a browser-supplied placeholder.
There are cases where each behavior is more functional.
For example, the Flashblock add-in for Firefox replaces each Flash
object with a placeholder which lets the user tell where they are,
and use them as a control to active them on a case-by-case basis. If
they were instead replaced by their fallback content, the user would
not have an easy way to activate the specific instances, and may not
even be able to tell that there are inactive objects...
