Nice job, Tony(<liquid@liquidimage.ca>) in discussing the economic
considerations of producing VR hardware.  I felt like I was back in school :

>Every industry has got to
>follow the same product evolution pattern - Innovation, Rising Star,
>Cash Cow, Old Dog. The arrival of cheaper products occur during the
>later stages of the cash cow stage (Major profit taking occurs here!)
>and the beginning of the Old Dog stage (get it out of our wearhouse at
>any cost!). Cheap systems do no occur right out of the gate

You're following quotations and comments make me feel that I need to
clarify myself.

>> >The fire service industry is always looking for better ways to train
>> >firefighters.  With the high cost ($1 million +) and low flexibility
>> >of live fire burn room simulators and increasingly tougher EPA
>> >regulations, the US Air Force turned to the VR industry in hopes of

First of all, the first two paragraphs are written by two different
people.  I did not suggest for the Air Force to use Quake and an HMD
in place of a live simulator.  We, at 5 Inc., are making the "world
class virtual fire simulator" that you suggest.

As I stated in the original article, we shouldn't walk into an
industry and try to convince them that we can immediately replace what
they've been doing for years.  Our approach needs to be one in which
we augment current methods first, establish the practicality of VR,
then aim for loftier goals.  Take a brief look at the history of AI
(I'm not an AI expert, this is simply the way I see it).  Originally,
many said that we would be able to equal the human brain in
intelligence.  This immediately turned many people off to the
industry.  As our AI technology evolved, and advances slowed, we
realized that we may never be able to equal the human brain in
intelligence.  At this point, more thought was put into the practical
applications of current AI technologies.  Our approach was not to
create something equal to human intelligence, but to create something
"smarter" than traditional comuputing methods.  Many saw AI as a dying
industry, but this was not the case.  Slowly, neural networks and
expert systems have crept into our daily lives.  Perhaps the VR
industry is going through a similar process - lofty, unrealistic
goals, claims of replacing our environment, attempts to dramatically
change the world as we know it, resulting in loss of confidence in the
technology.  I spoke with a friend recently who was interested in VR,
but had no experience in the area.  He wanted to know, "when you're in
VR do you know where you're at anymore, do you what to stay in, would
you just stay there forever if you could?"  We can't live up to such
expectations.

Some in our industry need to pursue technological advances.  Some of
us, however, need to tackle realistic problem domains with the
technology that is currently available.  The VR industry is growing
and will continue to grow, but I believe most often the growth will be
seen one small step at a time.
