<janina_> /me michaelc: EMERGENCY: Can't get in on Webex for APA with 647 857 439

<janina_> Argh. Webex is misbehaving. The 9 digit code isn't working for me

<janina_> No go here either via SIP (my usual) or direct dial PSTN

<janina_> Will try again

<scribe> scribe: MichielBijl

preview agenda with items from two minutes

JS: Hope to have Judy here today

are we doing enough?

are there missing pieces?

Welcome Ralph!

Any news or other relevant tidbits?

LW: We published a new update to HTML 5.2

Working draft update, no big milestone, nothing that impacts accessibility

Media Accessibility in W3C Specs

JS: we did a lot of work to make sure HTML 5 supports everything we can reasonably expect

We went through and came up with all kind use cases

Came up with a notes document

<janina_> http://www.w3.org/TR/media-accessibility-reqs/

That is the basis by which we talked to HTML about how to support it

It should not be a surprise that some of them text

Some of them are binary

Like video or audio files

And some of this is fixed up in use cases

I know we’re listed in a charter

Has just been renewed for another year

Some of the folks there are familiar with what we’re about

In some cases I’m seeing new names

Not sure if they’re aware of what we’re about

In some cases it’s hard to find out what an API is about

There’re enormous opportunities to get this right

Users at home

Educational videos

In a school setting for example

Or even in a movie theatre

HTML should be an inter-operable device

Make it possible for hearing impaired users to use their smart device to listen to the main track or audio described track

Maybe we have to update the MAUR

We did for visual impaired users

Not sure we did for hearing impaired users

Might have documented some issues, but not the solutions

You can find plenty of examples where you have subtitles and audio description

RS: Thank you for inviting me

<Ralph> [Ralph notes http://www.daltonize.org/ for Daltonization]

JF: I’m just curious

You made mention of delivering solutions

Was my understanding that the MAUR was about documenting use cases

<Zakim> JF, you wanted to ask if it is the role of the MAUR to deliver "solutions", rather than articulating needs?

JB: Motivation was to find the support between HTML and ??

We wanted to achieve a technology neutral document

With of those things in hand it should facilitate the technology options

Until we have that each meeting there is a discussion

scribe: a debate between which technology better address some user needs, TTML, or WebVTT?

We noticed that since then there are a couple of groups

That from time to time work in areas that relate to media accessibility, but without realizing the tie-ins such as the need for APIs, nor the availability of the MAUR doc

One aspect is colour schemes

Another is flash mitigation

We can just capture the colour scheme aspect and the flash mitigation

Happy to tell more about

it

JS: And very important

Also some legal ramifications

Make sure developers are aware of them

What we need to follow through on

Most of us have non real time things in mind

There is the real time world as well that we’re working on

All of them will probably come into play

If we think of an entity like Canada

About some thing

That they would stream

Being Canadian they have to do it in English and French.

But you would also like to support the third scenario

??

Also automatically decide which language you need

Not sure WebRTC is appropriate for that

We don’t have a standardised control

JF: I’m struggling to understand what it is we’re trying to achieve

JB: There’s still a very active a11y effort in W3C

We’re opparating in different ways

And media a11y issues come up sometimes

In unexpected placed

I think it may be useful to look at this question of where are media a11y opportunities coming up

What would the APA need

We want to drive the support for media a11y support

JF: There have been two specific issues

??

The other is about, lost the thread, switching between languages etc

Real time support

That somehow they can choose they can choose which audio stream they want to select?

JS: Yeah, and also video

RS: The content has to be there

Our scope here is to say the content should be available

And we need the infrastructure support

for users to choose languages

JS: ANd that last point is what APA is running into to

We need to review whether it’s relevant

We know it’s related to audio or something else

I spend a lot of time on MEDIA

We weren’t only talking about real time, but it’s hard to tell sometimes where it fits

Where these APIs fit in the larger picture

For APA one thing that is missing is how to place the APIs in the larger scheme

Sometimes it’s hard to start the conversation on that.

<Zakim> Judy, you wanted to ask a question

<Judy> https://www.w3.org/TR/media-accessibility-reqs/#toc

JB: Are you asking hey let’s look at maybe how can we make the document better known?

If you look at the structure of the document

There’re three main sections

1. Summary of Accessible Media Requirements by Type of Disability

2. Alternative Content Technologies

3. System Requirements

*description of these categories, please refer to document itself*

<JF> I am still confused. The use-cases Janina has risen seems (to me) to be covered in the MAUR already. For example, the ability to switch language streams should be covered by this: [DAC-3] The user can browse the alternatives and switch between them.

<JF> and perhaps this: [DAC-7] During time-based media playback, the user can determine which tracks are available and select or deselect tracks. These selections may override global default settings for captions, descriptions, etc.

JB: I’m thinking maybe coming up with structure questions to focus people’s attention could get us farther

Does that match at all what you’re trying to achieve with this document?

JS: It does for me

JB: John does it help you?

JF: I mean, you brought up a use case, I went and looked at the MAUR, we have two uses cases that fit your issues

JS: I think it might be point 2 and 3

Point 2 is a frequent issue for APA

What we expect a particular API to achieve

What could conceivable be picked up by implementers and the like

Then we start to look at do we ??

as well as APIs and so forth.

RS: John’s question makes an interesting point

As new WG are formed

It’s hard for different WGs to look at APIs and see what the intersections may be

If we remind them that the MAUR exists

If there is one thing I would encourage the APA to do

Is to publish an update

Would encourage to stage multiple updates

To get more exposure as you update regularly

JF: Want a sanity check

What I’m hearing is we’re talking about two things

1. Perhaps need to revisit MAUR and plug things

2. How do we socialise the MAUR

(within the W3C)

Am I understanding this correctly

JS & JB: Yes

JS: Or a spin off

MAUR 2: Die Harder

JS: Michael should we build this into the checklist?

Think we have an early draft

<Ralph> [publishing an update is one of the ways to socialize the resource]

Doesn’t include media yet

<MichaelC> http://w3c.github.io/pfwg/wtag/checklist.html

MC: So, I think in the APA we’ve been expected to come up with user requirements

<janina_> Yes to similar counterparts

Like payments(?)

<janina_> Like payments

The centralised checklist if you scroll down to the fourth big black bar (that’s WCAG fail Michael)

JB: Are you looking for volunteers?

JS: Yeah, I think so

A lot of us here are already overcomitted

JB: Iw ould be interested to contribute to ?? and the flash mitigation

GZ: I would volunteer

There are some standards coming up

For example how text is contained in frames

Something we should look at when we revise this document.

JS: Any other thoughts?

RS: Thanks for inviting me and would like to return from time to time

JS: Interested to learn how to socialise the MAUR

RS: One of our big goals

Judy has support from other seniors to spread this around

JS: Going once

going twice

sold!

JS: Michael, a question: are there any new publications?

Input Events http://lists.w3.org/Archives/Public/public-apa/2016Nov/0005.html

JS: This is a WP set of issues

We lost Rich S.

He was the last to review

We do have some comments from back in November

LW: Did they make it as far as the group working on the spec

JS: They might need some cleanup before we formally put them forward

Not exactly sure how to go about the cleanup

LW: Don’t mind taking a look at them

The group that are working on them have a planned call around 13th of February

I’ll prioritise this

JS: Do you want two weeks?

<janina_> ACTION: Leonie to move forward from Rich's start re Input Events http://lists.w3.org/Archives/Public/public-apa/2016Nov/0005.html due +2 weeks [recorded in http://www.w3.org/2017/01/25-apa-minutes.html#action01]

<trackbot> Created ACTION-2110 - Move forward from rich's start re input events http://lists.w3.org/archives/public/public-apa/2016nov/0005.html due +2 weeks [on Léonie Watson - due 2017-02-01].

LW: Yes, won’t be here next week, will try to respond to the list before then.

<MichaelC> action-2110 due 2 weeks

<trackbot> Set action-2110 Move forward from rich's start re input events http://lists.w3.org/archives/public/public-apa/2016nov/0005.html due +2 weeks due date to 2017-02-08.

Updating DOM--Any RFEs? https://lists.w3.org/Archives/Public/www-dom/2017JanMar/0000.html

JS: There’re various DOM specs open for review

Do we need to keep bringing this up

SM: Have discussed this with Rich, please keep on the list

JS: Will do!

MC: That’s related to Shadow DOM, are there any other DOM specs we need to track?

JS: All of them

MC: What’re all the DOM specs?

JS: Steve F. send something to the chairs list, can’t find it at the moment

MC: I don’t see it either

Wondering if we’re missing something in our Wiki

JS: I’ll find it

Not right now, but I’ll find it or drop the question

*boom*

APA's Accessibility Checklist

MC: Don’t feel it has had sufficient review

John has accepted to reviewed it

But nobody else has made any comments

LW: Is it worth asking some people outside the a11y community to get an outside review of it

MC: I’ve had some feedback, that it’s too wordy, needs editorial review

Give a couple weeks for that

And as a second round do what Léonie is suggesting

Not sure where to go there

But might be best to start with groups we work with

Ask them “will this make it easier to work with us”

Maybe the furthest we can go before the AC meeting

After that we can take it to a wider audience for input

JS: John, how much time do you think you need?

JF: Want to get the spreadsheet finished first

How about a week?

JS: Okay that sounds good

s/fine/good/

JS: Calling a CFC will put us all on record

Any other business

next and future meetings
