360 Image, NVDA, and Lightboxes

Sep 14, 2023

Good afternoon,

I have created a 360 degree image interaction in SL 360 with 6 markers. Each marker has a label and a button inserted in the label. The button jumps to a lightbox that is a graded multiple choice quiz. 

Using a screen reader (NVDA and TAB functionality), when the user returns to the 360 image, after receiving their feedback from quiz 1 to access the 2nd marker, it returns to where they last were; marker 1 - which is good. However, when the user returns to the image after answering question 2, and  TABS to access marker 3 for the 3rd question, it jumps back to the 1st marker. The user then has to tab to marker 2, then to marker 3 to access the 3rd question. This pattern is repeated for every subsequent marker. This forces the screen reader user to open marker 1 - 5 (to hear the progress for each marker) in order to know where marker 6 is. This puts unnecessary actions on the screen reader user and unnecessary extra TABs to experience the activity accessibly. Why does this occur when using a lightbox?

When triggering the button within each marker's label to jump to the question slide (instead of lightbox) it seems to function properly; returning to the correct location of the marker they last visited, in order to TAB to next marker without going through the all the markers.

Is this a bug, or is this functionality intentional?

I've attached a drafted .story file demonstrating this with both lightbox (scene 1) and slide (scene 2).

Along these same lines; what updates are in the making for the 360 images that allow for more triggers within the image to increase functionality similarly to slides. It would be nice to have the "this marker has been visited" so that users with screen readers know where they are at all times in the image.

Thank you and I look forward to guidance and ideas.

Hello Lisa,

Thanks for reaching out!

I can confirm that I was able to observe the same behavior on my end. I opened a case on your behalf so we can have our support engineers verify if the behavior is a bug or expected behavior. 

As a workaround, you can try setting the navigation of your 360° image to use 'Guided Tour' instead. I can confirm that using NVDA,  focus box will not reset to the very first marker after returning from one of the test slides. Here's a quick video which shows how using 'Guided Tour' affects the tabbing behavior.

Hope this helps!

Hi Joe,

Thank you for looking into and confirming my case. I truly appreciate it.

I did consider the guided tour approach. The order of the markers is not dependent on the content being presented and using guided tour minimizes the immersive experience for the majority of our learner population who do not use screen readers or assisted tools. I would hope to see the bug get fixed so that all learners have a similar experience.

Is there an estimated time I might know the status of the case?

Thank you again,

Hi Lisa!

Thank you for sharing the feedback!

I took a look at your support case which is being handled by my colleague Ian. It looks like Ian logged this issue as a software bug and replied to your e-mail with some workaround steps you can try.

  • If the guided tour approach doesn't fit your needs, I see that he also suggested using the trigger 'jump to slide' on the light-boxed slide, instead of 'close light-box', to jump back to the slide with the 360 image.
