Background: In YTS we have a way to pop the controls out of the wall onto a tablet. This was intended primarily for VR users, but I watch people use it on desktop all the time.

While our tablet is usable on desktop without major issues, it's basically mutually incompatible with TPV, since your avatar blocks the ability to see what you're holding (the tablet screen in this case, see attached image). Compounding this issue is the held item's distance adjustment overriding the scroll wheel, so the user is not even able to zoom into FPV to use the tablet unless they drop it and pick it up again afterwards.

I would like to have a way to detect if the user is in TPV, so we could gracefully degrade the tablet and any similar pickups.
