Luckily, tracking your physical keyboard in VR has already been a thing for a while, and it has both quite solid third-party[0] and first-party implementations[1] by now.

To clarify, when I say "tracking", I don't mean just being able to use your keyboard in VR. I mean being able to actually see your keyboard in VR, along with being able to see keycaps on the virtual representation of your keyboard.
