Possibly, < does think you'd have to contend with the bulk of the VR headset in such a case mind, and it's not going to be very useful being contained in a box as the internal cameras won't be able to sync to anything.
To be fair, < thinks given the presence of LCD displays, wearing a box on one's head isn't actually too difficult. < would have an LCD display for the outside that's controlled by a micro, and have that micro also connected to a camera on the bezel of the front screen, and have an internal LCD that could output to the screen so the wearer can see what's going on.
Might not have a full range of vision, but <thinks it'd be good enough.
...< kinda feels inclined to see if < could manage something like that, because it doesn't actually sound all too difficult to do come to think of it...
