360 Image, NVDA, and Lightboxes
Sep 14, 2023
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.
