I have custom comfortable full body VR, and I've done this exact thing in the photo. It is very uncomfortable and inconvenient after about 45 minutes, and is one of the major reasons why the Apple Vision Pro/XR flopped.

1. Typing at a steep angle is very slow and crap on your wrists
2. You look like you're in the ICU
3. You won't get any work done, because you could just take a nap instead, haha

Probably that's a trackball, and I second your second

I think the entire thing spins around in a giant circle in the centre of the room in order to generate centrifugal gravity. Seems like the most sensible way

For me, first immediate issue was,

"Now let me settle in with my comfy computer jeans and leather boots."

I bet that buttoned collar shirt has never seen Cheetos dust either.

Not quite, but you can hook 3 monitors up here lol
