I think the use-case for these is more VR focused, with the AR just being a "being able to notice when something needs your attention" feature (where you would respond to such an interrupt by taking the glasses off, not by trying to look at the interrupting thing through the glasses.)

I've heard people propose that these "screen in glasses" devices (like the Xreal Air) are useful for situations where you want a lot of visual real-estate but don't have the physical room for it — like in a dorm room, or on a plane. (Or at a library/coffee shop if you're not afraid of looking weird.)

Tangent: this use-case could likely just as well be solved today with zero-passthrough pure-VR glasses, with a small, low-quality outward-facing camera+microphone on the front, connected only to an internal background AI model running on its own core, that monitors your surroundings in order to nudge you within the VR view if something "interesting" happens in the real world. That'd be both a fair bit simpler/cheaper to implement than camera-based synced-reality AR, and higher-fidelity for the screen than passthrough-based AR.

† Which wouldn't even need to be a novel model — you could use the same one that cloud-recording security cameras use in the cloud to decide which footage is interesting enough to clip/preserve/remote-notify you about as an "event".
