I've tried to keep up with this literature and so have grown somewhat
familiar with the work of Wann, Mon-Williams, and Rushton.  To those
with more than a passing interest, I recommend their article in the
latest (at least the latest I have) issue of the SID Journal:

Mon-Williams, M., Wann, J. P., and Rushton, S. (1995).  Design factors
in stereoscopic virtual-reality displays.  Journal of the Society for
Information Display, 3/4, 207-210.

I'd like to tie two threads together here: For those of you familiar
with the HITLab's work on a virtual retinal display, how will this
affect the accommodative and vergence state of the eye?  Does this
display remove any of the problems associated with more conventional
HMDs?  Does it create new ones?  I got to look at an optical bench
model a few years ago and was impressed; however, I remember thinking
at the time, "This is going to require some human factors research to
perfect."  Last I heard, they were making good technological progress
(e.g., light sources, mechanical resonant scanner, holographic optical
elements, etc.): anyone know anything about the latest advances in
human factors with respect to this device?
