Agenda Review & Announcements;
janina: Early stage conversations regarding promoting a11y & AT
… A topic raised, is extend the a11y APIs
… Needs keep growing
… pronunciation for example, and automotive WG, XR immersive environments, ARIA discussing same
… if we undertake this, APA would be very involved and it would be a multi-year effort
David: we offer to test
janina: If this is to occur, the next step would be a W3C workshop likely 2022
… These are the Accessibility trees that are exposed to AT: iAccessible2, UIAutomation, atk/atspi...

Joshue108: Automotive TFis trying to develop a best practices document....
… and a vehicle specification that may have a11y implications
<Fazio> sounds interesring
paul_grenier: Pronunciation TF
… still waiting for feedback and working on communications
<Zakim> Lionel_Wolberger, you wanted to discuss personalization
<becky> scirbe: janina
<janina> Lionel_Wolberger: Personalization still wrangling whether we have 3 attributes or 1 ...
<janina> Lionel_Wolberger: Matt and John have been working on it via use cases
Lionel_Wolberger: Still hoping to move to CR soon
<Lionel_Wolberger> Fazio: COGA responded to way finding, mono audio, breadcrumbs, actionable targets
paul_grenier: hitting hard on mental health as well
Joshue108: Open survey with the FAST user needs, requesting review from APA
Discuss Media Stream Content Hints https://
lists.w3.org/ Archives/ Public/ public-apa/ 2021Jun/ 0001.html
Lionel_Wolberger: Media Stream Content Hints
Lionel_Wolberger: Provides an optional hint to give consumers info on making choices
Lionel_Wolberger: e.g. your audio codec in a Zoom call, phps a different codec?
Lionel_Wolberger: same for video
Lionel_Wolberger: Content hint definitely helpful for decoders
Lionel_Wolberger: phps should be clearer this could be beneficial to AT users
Lionel_Wolberger: Also, these hints are actually authored, so the hints could be authored with pwd in mind
Lionel_Wolberger: Also, spec makes no mention of support files
Lionel_Wolberger: No support for possibly linked media, e.g. 3rd party described video
becky: Is this hint for people who create/modify UI? How provided to user?
Lionel_Wolberger: Don't think in the UI
becky: not for end users?
becky: so at would take advantage
Lionel_Wolberger: not an UI/UX spec, but great impact on UI/UX
Lionel_Wolberger: also thought of 2 use cases not covered ...
Lionel_Wolberger: e.g. video content hints -- motion, you want to preserve display of motion
Lionel_Wolberger: so if motion with transcription/caption, those could become blurry
<Zakim> janina, you wanted to talk about captions
janina: asks about captions, still burned in?
jf: still far too common, e.g. facebook
jf: So agree with this use case
Lionel_Wolberger: suggests can make the observation that we prefer not burned in
<Fazio> good point
jf: Notes it's possible to have the one atop the other--a mess
Lionel_Wolberger: also thinking of ua and dom ...
Lionel_Wolberger: does the aapi pass this on?
Lionel_Wolberger: should we require ua passes hint to aapi
becky: not necessarily the specification's responsibility?
janina: so it's exposed somewhere
Lionel_Wolberger: yes, in the ua player
<Zakim> JF, you wanted to ask about metadata schemes?
jf: perhaps it should be addressed in metadata -- via the containing document
jf: maybe we need to promote a better authoring pattern
Joshue108: at may variously use, or not info from the dom
Joshue108: still variants, the old osm plus aapi still out there
becky: you wouldn't know at the doc level
becky: video may be coming from elsewhere, and containing page wouldn't know
becky: so it has to be part of the stream
jf: good point
jf: maybe embedded in the stream container
[discussion on next steps]
<JF> MP4 files can contain metadata as defined by the format standard, and in addition, can contain Extensible Metadata Platform (XMP) metadata. (source:: https://
<JF> Metadata: https://
Discuss Permissions and Permissions Policy https://
lists.w3.org/ Archives/ Public/ public-apa/ 2021Apr/ 0013.html
<JF> Metadata Pt. 3 https://
<Lionel_Wolberger> becky: Permissions can limit browser features
<Lionel_Wolberger> ... concern that this spec might be too low level
<Lionel_Wolberger> ... APA concern if browser capabilities are turned off
<Lionel_Wolberger> ... since turned off for everyone, it's not an a11y issue
<Lionel_Wolberger> janina: USB can be turned off? What if the AT is relying on USB?
<Lionel_Wolberger> becky: spatial tracking, picture in picture are both in there
<Lionel_Wolberger> Lionel_Wolberger: There are examples in the policy spec
<Lionel_Wolberger> becky: Add that implementers should be aware of the possibility of accessibilty features that rely on features that are switched off, e.g. an AT relying on USB
<Lionel_Wolberger> janina: If they are focused on iFrames thats fine
<Lionel_Wolberger> becky: They are talking about cross-browser issues as well
<Lionel_Wolberger> janina: Can we use this to disallow automatic audio auto-play
<Lionel_Wolberger> Lionel says to Janina and becky +1 to no audio and +1 to no auto-play
<Lionel_Wolberger> becky: I will provide the note
