While using W Industries "Virtuality" head mounted display, I found
it hard to fuse the two projected views of an object into one 3D object.

I presume what was happening was that my eyes were refusing to go 
cross-eyed enough to bring the object into true.

Is this a common problem ? What stimulus does the eye/brain need to
re-adjust the amount of cross-eyedness ? 

My guess is that the lack of surface detail or the lack of focus is 
the problem.

A head mounted display is trying to get ones eyes to do something
it is not used to, ie focus at one distance and go cross-eyed for
a different distance. If the object is far from the viewer, this is not
a problem, but close up (where we want a 3D effect!) it may be.
