What?! HMD's have proven themselves, time and time again, in numerous
volume applications.  Everything ranging from VR entertainment
systems, immersive VR theaters, to tradeshow booths have cost
effectively utilized HMDs to add punch to the presentation and enhance
the visualization experience.

HMDs are now being seen as a viable display solution like a CRT, LCD,
or projection system.  I acknowledge that HMDs are not perfect for
every situation, just as CRTs, LCDs and projection systems aren't
perfect either.

With respect to fancy I/O hardware, keyboards and mice also don't cut
it in volume applications.  The two most low tech of all I/O devices
are not feasible in volume applications.  The keyboard offers the user
with too much flexibility, the controls are not intuitive, and it is
prone to malfunction and "gumming up".  The mouse also has the same
downfalls.

All in all, people should look to any VR type interface devices
because they solve an interface problem not because they look cool or
give the application the VR moniker.  In the past, this was the case
with many applications.  Developers now have access to some of the
best HMDs ever and should not quickly discount them because of past
performance.

Whoa! Hang on a second. No place for an HMD in an operating room? The
operating room has been in dire need of HMDs for a long time now.
Companies such as Vista Medical and KEO have been working on high end
light weight products just for the operating room. ( See
http://biz.yahoo.com/bw/97/09/15/hprt_mdt_1.html for more info) We
have been working on an HMD that will be used in portable veterinary
ultrasound applications.  The Medical industry is just one of the many
industries that are using HMDs effectively and relatively
inexpensively.

As I stated before, HMDs are becoming more mainstream every day. They
are moving out of the labs and into solving day to day display
problems.  Check out the sci.virtual-worlds FAQ for a listing of all
HMD manufacturers - give one of us a call so we can show you how we
can help solve your display needs.
