What fresh hell is THIS now? - Patrick Lauke

    why does rawgit sometimes take forever to refresh when you push a change

    [dylanb] @powrsurg: the reason it scrolls is to do accurate determination of background elements in a cross browser way. elementFromPoint needs things to be visible to work properly.

    @jnurthen, because Rawgit loves the planet and wants to save engery.

    @jnurthen why do you hate the planet?

  6. MichielBijl @MichielBijl is postponing his lunch to keep to his “it's done before lunch time” claim…

    That is how it works right?

    It only works for as long as you can handle eating multiple meals at the same time.

    Wow. So I left after @dylanb's reply to me and at home wrote a Memory game with the goal to be responsive, use no JavaScript library, be completely accessible, and support the Gamepad API. I got the first two of those down. It is accessible (you can tab to each card), but I thought it would be nice to support the arrow keys as well. I was using elementFromPoint and found that the elements not being visible at the time was the cause of problems and I needed to re-work my code (though I instead chose to go to bed as it was 1 and I had to be up at 5:30)

    http://powrsurg.com/work/memory_game/ for anyone interested or has any further accessibility related points. I was contemplating let the user change the speed of the animation to help them deal with vestibular disorder and not just change the method of animation itself.

    I haven't tested the screen reader support yet, though I believe it should be good.
  13. powrsurg
    Mar 08 14:21
    I chose to use aria-hidden on the images instead of regular hidden so that the regular web browser preprocessor should still download them during normal page load, but they shouldn't be read out.
  14. powrsurg
    Mar 08 14:22
    I do intend to make it better, it's just something I choose to throw together starting at about 9 pm after a long day ... could use some more polish

    Also, has anyone seen http://blog.monotonous.org/2016/03/07/narrate-a-new-feature-in-firefox-nightly/ ?

    [pdroll] Is anyone aware of a way to add a javascript event listener to the "swipe" event when using VoiceOver in iOS Safari?
  17. MichielBijl
    Mar 08 14:34
    Not aware, but would be interested. Although I don't think that exists.
  18. MichielBijl
    Mar 08 14:34
    VO on iOS captures all movements.
  19. MichielBijl
    Mar 08 14:34
    Might be able to do tap+hold + then swipe?

    [mkduell] Hey guys! Does anyone know of a good resource for working with the android 'Talk Back' software for html apps?
    Specifically dealing with its (seemingly) quirky behaviour?
  21. powrsurg
    Mar 08 15:44
    Shouldn't screen reader software itself parse audio description tracks and read them out themselves? Why must HTML5 video players build out their own interface for reading them out themselves?
  22. powrsurg
    Mar 08 15:45
    I can do such, I just don't get why this is necessary.
  23. powrsurg
    Mar 08 15:45
    Or does Jaws and maybe VO do and NVDA doesn't?
  24. pkra
    Mar 08 16:05
    Hey slacker, is the Chrome Dev Tools Accessibility extension reliable for computed names?
  25. pkra
    Mar 08 16:06
    as in: for working out what, in theory, it should be?
  26. zakim-robot
    Mar 08 16:11
    [hmig] @powrsurg: I tested your game with VO and it does not read out the image alt text. It just says "button selected/button unselected.”
  27. MichielBijl
    Mar 08 16:28
    pkra: I assume it gets it from the a11y tree?
  28. MichielBijl
    Mar 08 16:28
    If you're on the mac, accessibility inspector is my go to tool for that.
  29. garcialo
    Mar 08 16:32
    I think I recall @alice saying something about how she's not actually able to get it from the a11y tree?
  30. garcialo
    Mar 08 16:32
    I usually glaze over at that point; I don't understand all that stuff as much as I should
  31. pkra
    Mar 08 16:33
    @MichielBijl I don't think so. The extension says it applies the algorithm from the spec (and AT doesn't read the same thing that the extension calculates but that could be a problem elsewhere)
  32. pkra
    Mar 08 16:33
    @garcialo ah, thanks.
  33. pkra
    Mar 08 16:35
    thanks for the mac pointer; I was mostly thinking about it from the perspective of debugging; having an independent party's opinion so to speak.
  34. pkra
    Mar 08 16:38
    @MichielBijl for example, that math example (with the label+MathML element) in the WAI-practices-WD is computed in a way that surprised me (and does not match any AT behavior).
  35. pkra
    Mar 08 16:38
    *computed in the chrome a11y devtool extensions
  36. pkra
    Mar 08 16:39
    (and the ATs differ as well, of course, because where would be the fun in this otherwise)
  37. powrsurg
    Mar 08 16:43
    @hmig: thank you. I just tested in NVDA and it only seems to read it out when I press a key down afterwords. I expected that setting the aria-hidden to false would mean that the alt text of the image would have been read out. Do I need to set some type of live region? Should I add the alt text to the alert?

    [dylanb] @pdroll: it is there, the event is jst not being delivered. You can allow it to be delovered by using gesture passsthrough mode
  39. zakim-robot
    Mar 08 18:10
    [dylanb] double-tap and hold for 1 second
  40. zakim-robot
    Mar 08 18:10
    [dylanb] you will hear a tone
  41. zakim-robot
    Mar 08 18:10
    [dylanb] swipe
  42. zakim-robot
    Mar 08 18:11
    [pdroll] Oh cool. Didn't realize that was a thing. I'll have to do some digging when in this mode
  43. MichielBijl
    Mar 08 18:46
    @pkra: ah, good to know.
  44. jnurthen
    Mar 08 20:17
    @pkra you can look at the code Chrome Dev Tools it is using for the name calculation at https://github.com/GoogleChrome/accessibility-developer-tools/blob/master/src/js/Properties.js#L236

    With Google having ended the authorship program, should this kind of markup change? 

    <address class="byline">     <img class="byline-avatar" src="https://api.adorable.io/avatars/285/corey%40adorable.io" width="64" height="64"/>     <a class="byline-name" href="/author/john-doe" rel="author">Patricia Magana</a> </address>

    Is this kind of markup still sound, or is there a better way to do it and it’s misguided to use <address> and rel="author" for a byline?

  46. powrsurg
    Mar 08 22:01
    just because Google isn't doing anything with it doesn't mean that rel="author" isn't still valid code ...
  47. stevefaulkner
    Mar 08 22:56
    @jonathantneal suggest if you want to do such stuff use microdata/rdfa
  48. stevefaulkner

    Or whatever voodoo is your bag
