    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.

    Users can have difficulty reading text or recognizing images that
    are shown against variable backgrounds. Background images can also
    be distracting, especially to some people with cognitive
    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.

    the wiki. [recorded in

    <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.

    scribe: , and prevents audio from automatically playing and
    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
    start flashing content that would be harmful to a user with
    photoepilepsy.

    <jeanne> Users should be in control of whether media plays
    automatically, it can interfere with assistive technology, be a
    distraction to other users in the vicinity, or start flashing
    content that would be harmful to a user with photoepilepsy.

    <jeanne> Users should be in control of whether media plays

    photoepilepsy.

    Users should be in control of whether media plays automatically, it
    can interfere with assistive technology, be a distraction to
    themselves or to other users in the vicinity, or start content that
    would be harmful to users with seizure disorders.

    <KimPatch> Jamie has epilepsy that's triggered by certain types of
    audio. She needs to be able to avoid audio that plays automatically
    when she visits a web page.

    Related Resource: Guideline 2.4 Help users avoid flashing that could
    cause seizures.

    <kford> Jill browses the web using a screen reader that requires her
    to listen to the text of web pages. She navigates to her favorite
    shopping site and is greeted with trumpets blaring and an announcer
    shouting "Sale, sale, sale!" The audio is so loud that she can no
    longer hear the web page content. Jill closes her browser and
    changes a setting titled Play Audio on Request to yes and visits her

    <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.

    <KimPatch> Jamie has epilepsy that's triggered by certain types of
    audio. She sets her browser so that content does not play
    automatically so she can be sure to avoid triggering her epilepsy
    when she visits a web page.

    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...
