GR: Earl brought to the fore the issue of 508 decision-making.
Opposite opinion came up in ATAG review. In ATAG, concerns
about application of Guidelines to purchasing requirements.
e) When building ftf agenda, think about which issues hang
on interpretation of specs. Take those to PF.
Send ftf agenda items to the list.
f) It looks like we will have phone conferencing at the ftf.
Anyone here interested in calling in?
Of those present, Madeleine would.
Action Ian/Jon - publish an agenda by tomorrow morning.

Refer to Ian's proposal.
Please think of questions for the FAQ.
http://lists.w3.org/Archives/Public/w3c-wai-ua/1999OctDec/0502.html
5) LC#138: "Synchronized equivalent" v. "Continuous Equivalent"/
Proposed
split of 2.5
http://cmos-eng.rehab.uiuc.edu/ua-issues/issues-linear.html#138
IJ: Refer to how addressed in 6 December draft to use only
terms "captions" and "auditory descriptions"
2.7 Allow the user to specify that captions and
auditory descriptions be rendered at
the same time as the associated auditory and
visual tracks.
MR: Problem with this wording is exclusion of other types
of synchronized alternatives.
MR: We might need joint GL/UA meeting to consider EH's proposal
http://lists.w3.org/Archives/Public/w3c-wai-ua/1999OctDec/0597.html
MR: People haven't done the text-to-speech synchronization yet.
Resolved: Need to coordinate meeting with GL WG.
Action Jon: Organize meeting with GL and AU (asking in particular
Geoff Freed, Marja Koivunen, Gregg Vanderheiden,
Wendy Chisholm, Eric Hansen).
Propose 15 December joint meeting during UAGL call.
Action Madeleine: Send counter proposal to EH's to the list.
5) LC#171: 3.4: What does natively rendering audio mean?
http://cmos-eng.rehab.uiuc.edu/ua-issues/issues-linear.html#171
DP: Since we moved the definition of "native" to include OS
features, does that mean we can remove it here?
DA: I think we meant in previous discussions that if a helper
app is doing the rendering, it's not the UA's responsibility.
IJ: Do any UAs do this natively today?
GR: If a plug-in manufacturer is reading these guidelines, mentioning
native support might help.
MR: Suppose a mainstream browser encounters a sound file. If the
browser is calling a plug in, the UA should be configurable
to not call the plug-in. Or is the plug-in monitoring content
for sound?
IJ: I agree with MR. I think the UA can control on/off of rendering
by choosing to "display" or not.
IJ: For the checkpoints related to volume (audio and speech),
if you use OS controls, then control of volume through the OS.
MR: Also, background audio doesn't mention "native" either.
DP: There seem to be a lot of things that happen where the
UA calls another. Is there a way to address these globally
in the document?
IJ: Comments on "applicability" welcome.
DP: Gregory brought up interesting point about "autoplay". Many
times an applet will let you control volume. Are we controlling
through this the browser or the UA that content has been handed
off to?
GR: The latter.
RESOLVED: (checkpoint numbers from [1]):
1) UA has the power to turn on/off rendering of audio. This
applies to 3.2, 3.3, 3.4.
Action Ian: Add clarifying Note to rationale
that UAs can turn off control of content
even if it passes content off for rendering.
2) (Applies to 4.12 and 4.15).
Remove native from 4.12 and clarify that
control of volume is possible through OS if the UA
using those controls.
[1] http://www.w3.org/WAI/UA/WD-WAI-USERAGENT-19991206/
IJ: Refer to related discussion on "native": 173.
http://cmos-eng.rehab.uiuc.edu/ua-issues/issues-linear.html#171
http://lists.w3.org/Archives/Public/w3c-wai-ua/1999OctDec/0603.html
MR: Seems harsh if the only solution is not accessible.
DA: But if you are providing a feature, you have to make it
accessible.
JG: What if you're in X-Windows?
IJ: I don't UAs to reimplement, but if they are using a feature
to provide a functionality, it's their responsibility.
Maybe UA designers will ask for more accessibility in the
OS.
JG: So if the Mac doesn't support the use of keyboard to move
among controls in a dialog box whose problem is it?
IJ: I think the UA, but I realize that you want to use system
controls.
GR: Take the case of HPR (native support for speech). The install
is self-voicing. But if you don't have NN installed, speech
stops before that point. Is that part of this discussion?
DA: There are third-party tools for the Mac that make it
accessible. ("ClickIt" by Teletools (?))
DA: If the underlying OS is not accessible, your browser is not
accessible.
DP: But you can make it accessible through your own UI.
/* DB Joins */
DB: I think we can live with with Ian's proposal.
http://lists.w3.org/Archives/Public/w3c-wai-ua/1999OctDec/0603.html
Conclusion: More discussion on the list. Discuss this at ftf with
IBM Team.
6) LC#135: Add incremental forward/rewind for audio, video, speech?
http://cmos-eng.rehab.uiuc.edu/ua-issues/issues-linear.html#135
Resolved:
* No objections to "fast forward" to 4.10 and 4.13.
MR: I thought "incremental" meant small discrete chunks. I don't
think variable speed of fast forward and incremental advance
are the same thing. Analogy: You want the page down key to
move you in small chunks.
IJ: Does anyone feel that this is a checkpoint level requirement:
advance advance/rewind in audio/video by N seconds (P2)
where N is configurable (P3).
DP: I think P2 since without this, difficult for people with physical
disabilities.
MR: I think this is more of a technique. It's also being done
already.
Action Ian: Send proposal on this to the list.
7) .LC#139: Need clarification of 4.11 (audio playback speed)
http://cmos-eng.rehab.uiuc.edu/ua-issues/issues-linear.html#139
Refers to 4.11 "Allow the user to control audio playback rate."
IJ: TV's comment is that speed control for general
audio not as important as for speech.
GR: Hard for streaming. I think TV's point is that acceleration is
just a convenience. Deceleration is different. More likely
that people with learning disabilities could use slower audio.
Also some users with blindness.
JG: It's possible to slow down streaming.
MR: Do we also require adjustment for pitch?
Action Denis: Write up text to explain why deceleration is
important for users.
Resolved:
* 4.11 is Priority 1 (Refer to Denis' action item)
* Change language of 4.11 to refer only to deceleration of audio.
* Usually Helper App or OS will be doing the rendering.
8) LC#164: Proposed change to wording of 4.8 in last call UAGL.
http://cmos-eng.rehab.uiuc.edu/ua-issues/issues-linear.html#164
MR: Note that 4.7 could have captions.
Resolved:
* Merge 4.7, 4.8, 4.11 and use MR's language but talk only
about deceleration.
http://lists.w3.org/Archives/Public/w3c-wai-ua/1999OctDec/0539.html
* Add a note about distortion to that checkpoint.
* Merge 4.10 and 4.13 and add animation.
* Clarify that in 4.9, position means graphically.
Adjourned 13:46 ET.
