Hi, I'm using PowerPoint to create a poster (single slide, A1) to present some research. I wanted to take the opportunity to open a dialogue about accessibility in my field and have taken steps to make sure it is accessible for neurodiverse and visually impaired viewers. As part of this I have been using the Accessibility feature.
I have now assigned a reading order to all elements of the poster, and added Alt Text to images and tables. However I am still running into several issues.
1. When I use the Check Accessibility feature, it still flags up a "Warning" to "check reading order". The reading order is set, but there is no obvious way to mark "check reading order" as resolved.
2. I have tried using Narrator to read the poster in PowerPoint presentation mode, but it does not appear to read anything. I am not sure whether this is because I am new to Narrator and am using it incorrectly, or perhaps because PowerPoint still wants me to "check reading order" and therefore has not actually set the reading order yet.
3. Ideally I would like to export it as a PDF and retain the accessibility features.
$1. However, when I try to get Narrator to read the PDF (in Edge) it only reads the window information and file name, and Edge's native PDF reader does read the document but is clearly not following my accessibility tags, as it does not identify any of my Alt Text or ignore elements I have marked as "decorative". It also read out the contents of tables rather than reading Alt Text I had assigned them instead.
Both of the latter two problems could either be be because of the "check reading order" issue, or because I am not using Narrator correctly (entirely possible - I am a novice), or something else entirely.
I would really appreciate if anyone has any insight into how to solve this. Thanks!
