Sorry to diverge from Woman in VR :-} BUT, in the process of developing 
a VR platform, I've come across an interesting question.  What are the 
human limiting degrees in vision and hearing?  What's that mean?  What
is our total range of vision? 180 degrees?  What about an individual
_human_ eye?  How much overlap is there between the two eyes?  How
about hearing?  Can each ear hear 360 degrees or does the meat get in
the way?  How much overlap is there between the ears as in the eyes?
I'm trying to figure this out so that information to a rendering system
can be reduced if I only want to render the right eye, etc.  As a
friend stated, "Good software will allow everything or better yet,
should be thought of NOT DISALLOWING ANYTHING!".  I need these values
so that the tests could be run using the senses I'm most familiar with
(mine) before I go onto FLY-like vision (-:  Any info would be greatly
appreciated.  THANKS!
