Did you consult any physiologists? Anyone who knows what’s acceptable to those muscles? There’s a reason eye glasses use lightweight materials. Then all the various treatments to make the lenses visually clear and comfortable.
Good idea. We're mostly working off experiences with other headsets and e.g. bike helmets here, but having harder data would be good.
It’s a cool idea. I remember dreaming of this sort of thing in HS. I’m sure there are medical professionals who’d be able to inform you for a consultation. Perhaps even wiring up some volunteers to see muscular activity with various weights. Or yeah maybe helmet design has tread this well.
If it's well-balanced I would imagine that it would work for long periods of time. We already have some evidence from people modifying other VR headset straps to balance the weight. I wasn't able to find any information about the total weight of the Simula One VRC, but I know personally that my motorcycle helmet is close to 4lbs and I have often worn that for days at a time with lots of head movement.
We don't publish the weight officially yet since we're not that far along the development cycle yet. Our target is 800g, but we need to find a good balance between battery life, thermal solution, and weight.
