I don't work for the part of Hughes that makes the helmet - but I have played
with it. I understand that there is a demo planned for I/ITSEC this year - and
it uses a Performer application on iR hardware - so what you'll be seeing is
"real".
It does indeed have accellerometers that feed the Performer code to allow a
little predictive stuff. I recollect that it also does some video raster
shifting to take out some of the high yaw rate effects.
I don't think the SigGraph paper is talking about the same helmet as the one
that we sell - but there are several on offer so I could easily be wrong.
