Jake,

Thank you very much for the thought filled review. I will add clarifications before today’s meeting where I can and capture outstanding issues where I cannot.

I did want to recommend for others stopping at the history and notes section as I used that to retain previous but no longer completely relevant work so we could go back to it during discussions.

I think there is a lot here we can discuss so thank you again.

Rachael

AND… personalization kind of methods… see also again: https://docs.google.com/spreadsheets/d/1yTpbJFsaadIbCigV15YK6bWB4xk_MoOgREjGMHHMVgQ/edit#gid=1983238719

> ·      Guideline/Functional Outcome (Scoring is handled at this level)
> o   Not sure after lot’s of tests… The methods contain the score and there are flavors to them making normalization needed.
> ·      1. Tests that do not require a judgement call (Yes/No)
> o   IF we have / apply adjectival rating, will we / do we want a baseline?
> o   If we want a baseline, we ALWAYS have a kind of yes/no to start with
> ·      2.Tests  with easy judgement call (A/B)
> o   Example: Should the image be alt=“” or alt=“[some text]”?
> o   The example given here is not easy… I remember well a discussion with Jon Avila on where he mentioned he wants alt text and I’ve created them as empty: https://a11yportal.com/

> o   Example: Do JAWS and NVDA users understand the alternative language when completing tasks?

> §  Usability is not adjectival rating, what kind of usability tests are we talking about here? Benchmarking?
> §  AT Testing, that is not a goal but a means, it helps but is not needed
> 15. Structure
> ·      (this needs a clear elaborated example, not a theory of some solutions we can thinks of, the devil is in the details…)
> ·      Is this an example of a guideline?
> ·      If so, there is no absolute relationship and order needed for the 1, 2 ,3, 4, and 5s.
> ·      Visually and programmatic need to be separated and tested for clear reasons, see my test work (can explain)
> ·      Headings are not necessary per se, what if you use LABELS or Legends or other ways to structure…?
> ·      Landmarks are not needed, also not technology agnostic
> ·      Nr 5.:
> o   Headings help users with limited cognition quickly orient to content and complete tasks
> o   Headings help screen reader users quickly navigate content
> §  What does this mean in this slide? Seems like an explanation of benefits, not test related…
> 16. Alternative Text
> ·      Have not worked on them
> 17. Visual Contrast/Affordances
> ·      This is not mature enough to make any judgement call yet
> ·      See my work at: https://docs.google.com/spreadsheets/d/1yTpbJFsaadIbCigV15YK6bWB4xk_MoOgREjGMHHMVgQ/edit#gid=1983238719
> ·      Have lots of findings for testing / scoring…
> 18. Clear Written Content
> ·      Have not worked on them
> 19. 20. 21. 22.
> ·      Lots of questions and gaps to solve before moving to this stage!
