Dear Readers of sci.virtual-worlds:

I am trying to calculate a decent average of acceleration potential
ratings of VGA/SVGA monitors and TVs that have been in the market for
the past five years.  If anyone has any information on this, I would
greatly appreciated if you would pass it on to me.  If possible,
please include the make and model of monitor/TV set.  This will help
me determine what would be the "safer" CRTs to use.

I would like to gather this information to help me and others develop
better and safer CRT-based Head-mounted displays.  I prefer to use
CRTs over LCDs because of the higher resolutions found in CRTs,
however I extremely concern with the possible health hazards of using
CRTs (electromagnetic fields and x-ray emissions).  I have enlisted
the help of a medical physicist and an electrical engineer of a
research institute to help me find methods to dramatically reduce
those risks.  So that if VR homebrewers which to use tv screens or
small VGA monitors for their HMD projects, I can at least provide an
idea of what materials can used to shield those CRTs.

The HMDs and head-coupled devices (eg. FakeSpace Labs' BOOM and Pivot
systems) that I and other participating VR homebrewers intend to make
are solely for academic use.  Thank you.

						Sincerely,
