Imagine just the eye and hand tracking with no screens. That could be a much smaller device and one can trade the screens for an interactive environment.

edit:
They already seem to have a beta VR application: https://aerodrums.com/3d-updates
Thank you for the plug. We're doing a Kickstarter right now for Aerodrums 2.
It will have support for VR passthrough. We'll add support for Apple Vision Pro and Meta Quest 3 as soon as they make it possible (if anyone has connections to speed that up, I am interested).
The project page is here: https://www.kickstarter.com/projects/aerodrums/aerodrums-2-a...
I make Aerodrums and that operates at 125Hz for the mocap. As far as I understand, Apple Vision Pro tracks hands at 83Hz. They would need to improve that (and provide developers what they need to do a good job determining the position of the drumstick tip), for an air drumming app to be possible without accessories that plays to a musical instrument standard.
I've replied elsehwere in the thread plugging our live Kickstarter for Aerodrums 2, check it out, it only has 7 days to go.
