You mean how there are no hands and arms attached to the guns? While it looks funny on a video like this, it doesn't bother you a bit while you're in there.
My best explanation is your brain doesn't really care about your limbs while you're holding something. Your attention is on the object.
Rendering fake arms and hands would be a bit off-putting, I think. VR isn't tracking the position of your elbows or fingers, so it would have to guess their positions, and pretty much anything that's doesn't match reality gets noticed by your brain.
Rendering nothing instead of the wrong thing is more immersive.
It bothers me. I was playing with the Vive and the controllers with the smooth trackpad and it was a really odd experience.
First I couldn't tell what I was doing as the pad was frictionless. Then I saw a little red light to indicate I was touching the pad and it would move around in a circle. Okay that was helpful.
Except when looking down and it I was weirded out by knowing by hands are there in real life but I couldn't see them. What the heck was going on? Shouldn't I be seeing myself there but I'm not?
It was sort of like looking into a mirror and not seeing a reflection and wondering if you're a vampire or something. Yes that sounds crazy but it was quite odd.
