Hi all, [+ Research Questions TF list on cc] Thanks Frances for starting this, and Christopher (happy to hear more from George). I was actually just preparing a mail for Christopher on this. So for some background. I've reviewed a spec called 'WebXR Layers API Level 1'. [1] I think there is an accessibility related concern. [2] To capture that here: The spec provides support for various layer types used in a WebXR session (adds 'composition' layers). It covers rendering, view creation, Video Layer creation, events and WebXR Device API stuff. It's mostly technical implementation details - but one thing that jumped out at me is that WebXR Layers API allows the rendering/re-rendering of certain content at different resolutions. So I was thinking this may have accessibility implications to ensure that important accessibility related content doesn't get scaled down. So the question is should we feedback to the immersive web group? Do we need to flag this to them or suggest a note is needed to say that captions or other accessibility content should be privileged and therefore not rendered poorly in certain contexts, such as when there are bottlenecks when rendering, or limited bandwidth? What would also be useful to us in Research Questions would be evidence that captions actually need to be high resolution, or if there known issues with low resolution captions in certain contexts in immersive environments. Or indeed any other info you deem useful! Appreciated, and if you have any questions please let me know.
