VR drones are already used in combat by both the Russians and Ukrainians though. I guess they don’t fly very far so maybe there isn’t enough time to get disoriented and dizzy?
Not quite, fpv is single camera angle which can't exactly be directly compared to a VR setup which is stimulating a full field of view.
A real life 360 video is recorded using something like this:
The view the user sees from a VR headset is Stitched and moved around from the fixed camera angles, as expected this is computationally expensive and requires very low latency and almost perfect video synchronisation to prevent imagery glitches causing nausea.
I believe the tech has gotten a lot better in the last few years just due to the large increase in computing power, but I'm still unsure whether it is good enough to apply directly into earth moving equipment.
One way to get around this flaw as funny as it sounds is to just stick with a virtual cockpit, with the actual camera view outside each window of the equipment rendered in the cockpit windows rather than being immersed in a purely 360 camera view outside the vehicle, that will pretty much completely rid of the issues I have mentioned, but then why not just ditch the VR?
VR equipment is becoming commonplace for heavy vehicles simulators for training purposes, but I haven't really seen anyone try controlling vehicle from VR.
