[Locked Figure Aria] Locked function aria labels (graph + editor) #1687

nishasy · 2024-09-26T23:46:52Z

Summary:

Add ariaLabel field to LockedFunctionType
Add the aria label behavior to the LockedFunction on the mafs graph
Use LockedFigureAria within LockedFunctionSettings
Write the function to auto-generate the locked function aria label
with its coordinates and visible labels.

Issue: https://khanacademy.atlassian.net/browse/LEMS-2380

Test plan:

yarn jest packages/perseus/src/widgets/interactive-graphs/interactive-graph.test.tsx
yarn jest packages/perseus-editor/src/widgets/interactive-graph-editor/locked-figures/locked-function-settings.test.tsx

Storybook

Graph behavior

Go to http://localhost:6006/iframe.html?args=&id=perseuseditor-widgets-interactive-graph--mafs-with-locked-figure-labels-all-flags&viewMode=story
Use a screen reader to navigate through the preview graph
Using the screenreader controls (VO + arrow keys) should be able to navigate to the locked function. It should read out as "Function E".

Editor

Confirm that the locked function aria label field is already populated with "Function E" (passed in via builder)
Confirm that pressing "Auto-generate" works with no labels, one label, and multiple labels
Confirm that updating the aria label in the editor also updates the aria label on the function
- Check the web inspector to confirm the aria-label text is updated
- Use a screen reader to confirm the new label is read out

Why is aria-hidden needed here? Does the screenreader read something for this SVG element if there's no aria-label?

Yes! It says "empty group"

Maybe this label shouldn't contain Ellipse - just to avoid confusion :)

+            str += `, ${domainRangeText} from ${domain[0]} to ${domain[1]}`;


I think, rather than using ${domainRangeText}, we always want this word to be domain. IIUC, the domain of a function is always the set of input values, so if the function has the form x = f(y), the domain is a set of y coordinates.

Might be good to confirm this with math content creators, though.

That is a good point! I'll ask

I haven't gotten a response from the content authors yet, but I think you're right. I'll change it to domain here and in the editor UI. If a change is requested in the future, we can update it. For now, I'd like to unblock this so I can keep landing all the PRs stacked on top of this.

… referring to input values.

Does the label component for domain min also need an aria label like the domain max one?

No, it's automatically labeled by the label itself. You can see in the test file that the aria labels successfully get set as "domain min" and "domain max".

Should there be an additional check to validate that there is text added to the labels? Or make the text a required field if the button to add a visible label is clicked?

I did think about that, and that is a good point. I do agree with you. Unfortunately, validation in the content editor has been deprioritized in favor of just trusting the content authors and giving them ultimate freedom. The content authors should definitely be checking that the label makes sense before saving this on the exercise.

If this ends up being an issue and content authors ask for extra validation, we would definitely add that in the future.

LGTM!
