<kford> Topic, User Agent Accessibility Guidelines Weekly Telecon
2010-10-14 at 1700h UTC

I think so, perhaps we didn't close them, and zakim carried them forward

i haven't a clue

kelly, just say "agenda order is " and put in the items in the order
you want to present them (5, 3, 1, 2, 4) and it will reorder them 5 as
1 etc.

<jeanne> keep trying, there are system problems

<kford> \zakim, microsoft is kford

Suggested rewrite of 3.7 (Provide volume configuration) from Greg
Lowney http://lists.w3.org/Archives/Public/w3c-wai-ua/2010OctDec/0015.html

<Greg> Here's my suggested rewrite from email:

<Greg> Guideline 3.7 Provide volume control.

<Greg> Upshot: Let users adjust the volume of each audio track
relative to the system volume, but respect global mute settings by
default (3.7.1).

<Greg> 3.7.1 Audio Volume Control:* The user can /independently/
adjust the volume of all audio tracks
<http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-audio-track>
the user agent renders, /relative/ to the global volume level set
through operating environment
<http://www.w3.org/WAI/UA/2010/ED-UAAG20-20100920/Overview.html#def-operating-environment>
mechanisms. However, the user...

<Greg> ...agent should not override a global option that says audio
should be muted unless this is optional, not enabled by default, and
the user is cautioned as to its implications. [Alternate wording:
/However, if audio is muted as the global level the user agent should
not override this unless the behavior is optional, not enabled by
default, and the user is cautioned as to its implications.]...

<Greg> ...(Level A)

mh: likes rewrite, questions alert mechanism

<Greg> By cautioning the user, I was imagining that the dialog box
with a check box to override the default behavior could have static
text cautioning the user, OR the user agent could prompt the user for
confirmation when they try to turn on the overriding.

kf: any SC for synthesized speech. is this only about rendered speech,
and not adjusting audio for talking UA

gl: nothing in the SC that says only rendered

mh, kf: but 'track' implies rendered audio.

kf: as long as we have SC for synthesizers, combining makes sense.

ja: confirms that 3.8 covers synthesized speech.

gl: software can't set volume independently, only relative to OS volume level.

kf: 3.7 is about rendered content (even audio file containing
synthesized speech)
... poll combine 3.7.1 and 2

all: yes

js: in toto a bit confusing, need to reword, or reorder the examples
... likes volume control vs volume configuration

ja: +1

propose wording:

<jeanne> 3.7.1 Audio Volume Control:* The user can /independently/
adjust the volume of all audio tracks
<http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-audio-track>
the user agent renders, /relative /to the global volume level set
through operating environment
<http://www.w3.org/WAI/UA/2010/ED-UAAG20-20100920/Overview.html#def-operating-environment>
mechanisms. However, if audio is

<jeanne> muted as the global level the user agent should not override
this unless the behavior is optional, not enabled by default, and the
user is cautioned as to its implications. (e.g. the alarm clock
application on a mobile device has an option to play the alarm even if
the system is muted, provided the check box is normally unchecked and
is accompanied by text cautioning the user about this behavior.

<jeanne> (Level A)*

<kford> ACTION: kford to provided updated text for implementing of
combined 3.7.1 and 3.7.2 [recorded in
http://www.w3.org/2010/10/14-ua-minutes.html#action01]

<trackbot> Created ACTION-455 - Provided updated text for implementing
of combined 3.7.1 and 3.7.2 [on Kelly Ford - due 2010-10-21].

jr: wording for 3.7.1 seems a bit long

<jeanne> ACTION: jeanne to update 3.7.1 with the text above - Audio
Volume Control [recorded in
http://www.w3.org/2010/10/14-ua-minutes.html#action02]

<trackbot> Created ACTION-456 - Update 3.7.1 with the text above -
Audio Volume Control [on Jeanne Spellman - due 2010-10-21].

gl: note at end was added, so readers would not have to read
implementing document to understand SC

jr: this is a lot to parse

<Greg> Could shorten the parenthetical example to read only "(e.g. an
alarm clock application has an option to play the alarm even if the
system is muted)."

jr: if the global volume level is set to mute, then independently
setting volume level above mute requires user confirmation or warning

gl: could flesh out in the implementation (more examples)

discussion of master control, and independent volume control

kf: accessibility - user can set volumes, up to the OS as to implementation

gl: add content from original email into implementation doc. would that help

kf: exception is longer than the rule.

jr: what is the accessibility issue

<kford> kford incorporate percentage volume concept in example.

kf: JS to use discretion for wording of new 3.7.1, kf will add
volume/mute info to examples

Problems with 3.5.2 from Greg Lowney
http://lists.w3.org/Archives/Public/w3c-wai-ua/2010OctDec/0011.html

<Greg> Here is one of the two proposed wordings from the email:

<Greg> 3.5.1 Highlighted items: The user has the option to highlight
the following classes of information so that each is uniquely
distinguished:

<Greg> * (a) selection,

<Greg> * (b) content focus,

<Greg> * (c) recognized enabled elements, and

<Greg> * (d) recently visited links.

<Greg> The highlighting options (with the same configurable range as
the operating environment's conventional selection utilities) include
at least (Level A):

<Greg> * (a) foreground colors,

<Greg> * (b) background colors, and

<Greg> * (c) outline (with configurable color and width).

<Greg> The changes from the current wording are (a) combining 3.5.2
into 3.5.1, and (b) changing the "input focus" attribute to "outline".

<Greg> The email also included a version which did NOT combine 3.5.2
into 3.5.1, instead revising 3.5.2 to refer explicitly to 3.5.1, as:

<Greg> 3.5.2 Highlighting options: When complying with 3.5.1, the
highlighting options (with the same configurable range as the
operating environment's conventional selection utilities) include at
least (Level A):

<Greg> * (a) foreground colors,

<Greg> * (b) background colors, and

<Greg> * (c) outline (with configurable color and width).

a good article on focus control by Patrick Lauke
http://24ways.org/2009/dont-lose-your-focus

jr: want to keep separate with reference to 3.5.1

kf: likes separate

mh: +1

ja: +1

gl: +1

<Greg> In my latest email I gave three possible wordings for the
outline bullet item:

proposed wording for 3.5.1 & 2

<Greg> * "outline (with configurable color and width)", or

<Greg> * "outline (with configurable color and width, e.g. the CSS
outline attribute)", or

<Greg> * "outline (with configurable width and color, including inversion)"

*3.5.1 Highlighted items:* The user has the option to highlight
<http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-highlight>
the following classes of information so that each is uniquely
distinguished. (Level A):

* *(a) selection*,

* *(b) content focus*,

* *(c) recognized
<http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-recognize>
enabled elements*, and

* *(d) recently visited links*.

*3.5.2 Highlighting options:* When complying with 3.5.1, the
highlighting options (with the same configurable range as the
operating environment's
<http://www.w3.org/WAI/UA/2010/ED-IMPLEMENTING-UAAG20-20100920/#def-operating-environment>
conventional selection utilities) include at least (Level A):

* *(a) foreground colors*,

* *(b) background colors*, and

* *(c) "outline (with configurable color and width, e.g. the CSS
outline attribute)"

<jeanne> ACTION: jeanne to combine 3.5.1 and 3.5.2 using the text
above [recorded in
http://www.w3.org/2010/10/14-ua-minutes.html#action03]

<trackbot> Created ACTION-457 - Combine 3.5.1 and 3.5.2 using the text
above [on Jeanne Spellman - due 2010-10-21].

<Greg> The CSS outline attribute covers color (including inversion),
width, style (solid, dashed, etc.). Do we want to require all of
those, or just color and width?

<kford> JAllan: If css chnages we don't want to have our item become outdated.

jr: may be other UA (flash) so may be other ways to 'outline' something

gl: advocates for inversion and animation for highly visible focus

<kford> +1

<Greg> The only way to get an outline that is guaranteed to be visible
is to use inversion, and even better with inversion and animation
(e.g. the original marching ants).

jr: agree with adding inversion

ja: +1

<Greg> "outline (with configurable width and color, including inversion)"

DOM3 Review - http://www.w3.org/TR/2010/WD-DOM-Level-3-Events-20100907/

<kford> JA: I looked at this spec. Lots of stuff in there. Kind of
wish Gregory was here because I think he has some serious concerns.

<kford> JA: Events on tab key for example. What to do in an edit box.

<kford> JA: loads of mouse events that have cancel but for some
keyboard events unable to cancel.

<kford> JA: How do you cancel a key down for example?

<kford> Kelly and Jim to follow up with Gregory on his concerns. PF
also now taking part of this up.
