So, I'm guessing it was tethered to a pretty high-spec PC?
explaining objective physical deficiency (Laws of Nature) of hardware with software compatibility reasons...
Just how well you can "inside-out" track an HMD inside a big hall with white painted walls and ceiling ?
Depth cameras might help ($$$) but still..
idiots, just idiots
Chill, dude. Keep yer angry to yerself.
Yes, we understand the limits of cameras - esp. all are front-facing. From what he said, the issue is controller tracking, which makes sense. Vive games track controllers, even when they'd be out of sight of the HMD's cameras (e.g. behind you).
Maybe some of their customers don't mind these limitations and would rather avoid the added expense of lighthouses. Other customers might need the flexibility.
I think it's more impressive that it demo'd well without lighthouses. If they managed that, maybe the next gen will add a couple cameras in other directions and forego the lighthouses.
