JAWS is behaving differently (more or less correctly) today. Not sure if settings have been altered. |
|
Did notice that in the scene summary, JAWS will read out "rho is 0.50 bullet ..." Wondering why "bullet" is in there. EDIT: Understand meaning of bullet now, not an issue. |
|
Also noticed that using keyboard navigation and JAWS leads to some performance issues if the sliders aren't increased or decreased in discrete steps. In other words, if you press and hold an arrow key to increase or decrease, there will be some lag between input and the sim moving the slider up or down. |
|
Update: NVDA is behaving correctly. I did some testing yesterday and today. I think the NVDA issues were related to settings. JAWS, on the other hand, is not behaving correctly. Here are the issues I'm seeing with JAWS:

Did some VoiceOver testing this morning, and I'm wondering why VoiceOver isn't reading the sim description. |
Regarding these kinds of issues, the screen reader might not read the entire sim every page load. @lmulhall-phet are you still able to read the sim description with the reading keys? |
|
@jessegreenberg Yes, sorry. My fault. Difficult to transition between the screen readers. VoiceOver looks good. |
|
@lmulhall-phet the same question applies to JAWS, are you able to read the sim description with reading keys, even if it doesn't read through on load? |
|
@jessegreenberg using default settings, I'm unable to get JAWS to read the sim description using insert+down arrow, insert+B, caps lock+a, or caps lock+down arrow. |
|
Sorry @lmulhall-phet I am not able to reproduce this. I just tried with JAWS and Firefox, I am able to read through the scene summary, hear the correct alerts about the equation, and so on. I will try on hanson tomorrow. |
|
@jessegreenberg then if I had to guess, I’d say it’s probably just ineptitude on my part. I probably should have spent more time getting familiar with the JAWS keystrokes and screen readers in general before logging the issue. Sorry about that. |
|
No worries at all @lmulhall-phet, @phet-steele and I were able to reproduce the problem today. @phet-steele and I played with the sim. At first the problem was there. We restarted FF and the problem went away. Then he was able to make the problem resurface after doing both of these
We aren't sure which one is causing the problem yet. |
|
I just did the above steps on my machine and encountered the same problem. Restarting FF made the problem go away. Going to try to reproduce with another non-PhET webpage. |
|
I did the above steps with reddit.com, and encountered the same problem. This is not a PhET problem. |
|
I tried insert+z to toggle virtual cursor on and off, had no impact. We should submit a bug report to FF. |
|
I submitted a bug report to Firefox about this issue in the above a11y-research issue. Thanks @lmulhall-phet and @phet-steele for reporting this problem and looking into it. It sounds like the best way to prevent this is to
Any other order may or may not work with JAWS. Closing. |

Problem description:
NVDA, JAWS, and VoiceOver aren't behaving similarly. NVDA and JAWS are, I think, not behaving how they're supposed to. JAWS is much worse than NVDA in this regard. I hope this issue can be an overview/outline of the issues we find with JAWS and NVDA. I already made an issue for a specific odd behavior I found in JAWS (/issues/131). I think we should try to keep track of all of these odd behaviors in this issue. This is for phetsims/qa/issues/92.
Please feel free to add any issues you encounter with any of the screen readers.
VoiceOver > NVDA > JAWS.
