title: ARIA Deep Dive - Should form field in cells have name computed from table/grid headers

aardrian6: assume everyone has read the comment

aardrian6: take accname and add another step. If there is a field with no accname but sufficient context then give it that accname

aardrian6: has to have a col/row header associated - if both then would concatenate

aardrian6: broadly my goal is to provide a guessable accname for voice users

aardrian6: and for screen reader users

aardrian6: and also to provide some redundancy for screen reader users would need coordination with AT vendors to coordinate

matt: I read the proposal and understand what you are proposing. Do you think this discussion needs to revolve around the pros and cons of whether this is done at all?

matt: if we don't do this what would we do to solve the problem. What would you like the scope to be?

aardrian6: figured folks who are familiar could do that

matt: what are the plusses of an automatically generated name

matt: versus the cons especially around edge cases.

aardrian6: edge cases... and corner cases where authors would override

matt: this is intended to be a fallback name calculation

aardrian6: i work with authors all the time with these data sttructures who don't want a visible label

giacomo-petri: are you saying that this fallback is a valid solution or is this a fallback that would be managed by user agents

aardrian6: initial thought is that this is just a fallback. but then maybe if this gets iimplemented then would maybe create a wcag technique

matt: seems like a good approach

matt: still womdering whether or not we want it to be an explicit wcag technique

jamesn: would also need stuff in HTML-AAM too

https://www.w3.org/TR/html-aam-1.0/#accname-computation

aardrian6: take a little further and look at headers and id. When it comes to contructs that don't have great support. my model is looking at simpler tables

aardrian6: do we run at what support looks like now. or do we wait for browsers to implement that stuff and build it in to that

aardrian6: my thought is that browsers are already responsible for coming up with that.

jongund: there seems to be a difference between grids and static tables. tables would use tabs, grids generally arrow keys. in a static table what do screen readers do now if there is no label
… if using table commands get the label

aardrian6: propose grids and tables are the same
… if via cell navigation you are already hearing this new info - need to discuss with AT how they would do that

jongund: seems like in the past accname type issues - browser developers were hesitant to make changes

aardrian6: understand that concern

jamesn: not super concerned about this

jongund: would we limit to native HTML

aardrian6: th and role columnheader/rowheader are functin

ally the same thing

jongund: don't think it should be a fallback

aardrian6: techniques includes failures and sufficient techniques

jamesn: how do we do it so that AT can make it less verbose?

jamesn: you can do this today, and if you did do it today, how can we communicate to AT that they should not communicate this information

jamesn: in the accessibility API, the AT will not know how the accessible name got there

jamesn: they will have to use context clues

matt: this is good for ARIA-AT

matt: good for ARIA-AT

jongund: already deal with this

matt: but right now they don't deal with this really

matt: the only way we can figure that out is by having a set of test cases

matt: we can write a should expectation in ARIA AT not a must

giacomo-petri:

giacomo-petri: was going to say the input name should be the same as the row/column header. You have the repetition right now. Of course would be necessary for the future.

giacomo-petri: lets assume this proposal comes off. If AT would support this then at the very end this solution would be more accessible. With this solution if AT avoid the repetiition then it would be much less verbose

matt: if this is adopted then it doesn't change anything for AT developers. I think they have to solve the double speak problem today

matt: this is just 1 more way of a browser calculating an explicit name. Any of todays explicit name techniques then AT already has to do things today to avoid extra speech

CurtBellew: Q about a scenario. What do you do when there are multiple controls or a radio group in a cell

aardrian6: if you have multiple then you get the same accname

giacomo-petri: if AT that supports this structure by announcing once. What happens if the author is customizing the accname?

aardrian6: if there are 2 controls and neither has an accname. they both get the same accname. If 1 has an accname and the other doesn't then 1 would follow this.

jongund: more things will get accessible names

StefanS: want to ask if thisn't more a discussion about what screen readers should do not what screen readers should do

<giacomo-petri> <td><input type="text" ... aria-label="input 1"></td><td><input type="text" ...></td>

StefanS: should behave like a table - what a screen reader can do is look at the relationship of the cell.... more a requirement for screen reader builders

aardrian6: no this is not for just screen readers. The accname should be in the browser

aardrian6: redundant fields.... authors should already be doing that

aardrian6: someone should be raising the issue that all fields had the same accname - authors can do all sorts of things.

aardrian6: if someone has the same button 10 times then this doesn't change that

giacomo-petri: we are saying that AT should end the redundancy. Have some cells with an input with no accname but other table cells with multiple inputs then need an accname. Would the AT provide inconsistent feedback. Then the AT would no longer be able to recognise that the AT has been cusotmized

aardrian6: the author is always required to provide an accname. if this lands with support then doesn't change the fact that authors need to provide accessible names

giacomo-petri: talking about consistency

aardrian6: if i am navigating table cells using a virtual cursor then already a verbose experience. Then will hear the accessible name of the fields

aardrian6: would need conversations

jongund: Q? for screen reader users - would row or column number be useful?

matt: no

Mario_B: users decision to hear the number or not

Mario_B: propose to have exact order for accname. If have in a table column headers and row headers we need to say in which order we take these headers into the accname. It is important as the screen readers can then more easily decide how to mute some announcements

aardrian6: would use columnheader and rowheader to build the name. The screen reader would then be able to decide if they want to announce it all or try to concatenate. If the screen reader wants to split that would be up to the screen reader

aardrian6: feel like it is a heavier lift to do that

general consensus is that we should go forward with this
