Read 'IEEE Journal of Solid-State Circuits, vol.27, december 1992'
It's about a multishanked probe, designed for highly selective
long-term stimulation of neuronal assemblies in the central nervous
system.  It incorporates on-chip (8 bits) DACs to stimulate the
nerves. Data can be pumped in with 4MHz bandwith. There are
microphotos also published, so it has been done...

Hi everyone,
 
Do any of you know of currently/soon/maybe feasible applications for VR in
the field of clinical/research medicine/surgery?
 
If so, I'd really like to hear from you, either here or via email.
 
Many thanks in advance for any info.
 
And MERRY CHRISTMAS ALL! (And cheers especially to Bob & Mark!)

Beside phylosophical speculations, the "common agreement" is that AR
is a Virtual Reality where you interact without cumbersome equipment,
like in Myron Krueger systems. He recently said that both VR and AR
are following the same ideal: interaction thru your body. They just
focus, he added, on different aspects. His work focuses more on the
INTERACTION, while VR focuses more on INTERFACE. Guess what's better
according to Myron's opinion...

Gosh, I don't know about real research or real systems in this area,

Jonathan,

I am interested how you define VR in medicine.

We are working on a system to combine live video images with any kind
of medical image data and also with 3D sensor data. It can be used for
analyzing the motion of the human body, but also for 3D monitoring of
endoscopic surgery. The basic idea is simple, we visualize any object
(surgical instrument, part of the body) where you can attach a 3D
sensor.  We do not use a HUD, so it is not the immersive experience.
But as we track the video camera we could track the head movement as
well.

We do have PAL tapes, though I haven't watched them through (there was
some concern about the audio quality).  If there's interest we could
of course convert to NTSC.  (It's rather expensive to convert, so we'd
rather have some orders for tapes first to break down the cost of it.)

I haven't tried this, but I imagine it depends on how fast the LCD
panel is.  If it is as slow as most I've seen, there's no way it will
be able to alternernate the left and right frames fast enough.  The
left frame won't have faded by the time the right eye's shutter opens
and both eyes will see both images superimposed.  Give it a try if you
can though.  It might work.

I have to agree that the Video Toaster is not meant for VR. At least
not directly.  However for those who don't know already, Virtuality,
the creators of the first public VR "game" "Dactyl Nightmare" runs on
a custom Amiga setup.  This is pre-AGA as well so future Virtuality
games should be even more impressive if they use the newest chipset.

I think that the IBM is good for VR as well, so is the Mac, and even a
Cray! ;-) The argument is moot and only comes down to $$, experience,
and what platform you prefer. Me?  Gee, I think those Amiga chipset
are *soo* cool!
 
:-)

BTW, *ALOT* of the prices I've been reading for the Amiga are off by a
few $$.  Here's the current prices:

A3000 = $1499 w/software
A4000 = $2695 ( ? )
A1200 = $599 list = $500-$550 retail
A600 = don't get this
A500 = discontinued

TTYL.

        Do you know of any companies / people who have any??

I still haven't heard about the toshiba glasses!!

And in England they drive on the right! Just joking, of course.  Also
here at my University it is preferred Artificial Reality.  I just
hoped that the taxonomy introduced last year during the SIGGRAPH
Tomorrow Realities (VR, AR or Third Person, and Desktop-Vehicle) had
been more widely accepted...

I recall an old conference (1988) on "Electronic Communication":
during the Q&A session a man stood up, saying that he didn't like the
term "hypertext" and proposing a brain-storming session to come up
with another name... of course everybody laughed...

I think that a common agreement should be reached one day or another
or we'll always see the abstract of the conference begin with "VR is
..."  Ok... we know. Nobody would start a SIGGRAPH paper with
"Computer Graphics is ..."

1 cent.

Then let me be the first.  :)

The two machines located at "Quarters", in Kirkland, Washington (USA),
use Polhemus trackers.

Either that, or the programmer who put "Initializing Polhemi..."  into
the Amiga startup sequence was a complete bozo.  ;)

Perhaps they've recently swapped over to Ascension, though, because
these machines have been there for quite awhile now.

Is there a standard mechanical guideline for making those spinning
things you stand in like on "the lawnmower man"?

I was just wondering if there was some tried and true design that all
builders follow or whether anyone building them goes and does it any
way they think will work.

I know they have been around for a long time and I don't want to
re-invent this sort of thing, but I could think of two basic
approaches:

***************************

***************************

And a slightly different one where some of the pivoting joints are
tilted at 45 degrees to the ground.

Am I wrong when I suspect that most combinations can produce the same
movements?

Are there any references anyone can point me towards on this subject?
Tech-reports, papers, books, etc.

I heard of a system that worked something like this:

CAT/PET scans were taken of a patient suffering from <name-your-
favourite-tumor> and built up into a 3D model.  The surgeon then dons
the VR-ware and makes some gesture (pointing I think). As he points, a
beam appears from his finger, representing the beam of some gamma ray
tumor zapper.

The surgeon can look in, around, under etc. the organs to the tumor,
and plan a path for the gamma beam through the patient that will
affect the least number of healthy organs.

When she/he finds a suitable path, another gesture is performed to
tell the computer to remember the beam's position. The surgeon can
place as many of these beams as they deem necessary for the operation,
with the computer storing their location. The current postion of the
organs is tracked by the computer, so that the positions of the beams
are updated if the patient moves. When the surgeon is ready, the gamma
ray zappers are powered up and the tumor is fried into the middle of
next week.

The whole story went something like that. I'm not sure if it was in
use, or planned, or just an idea someone had, but it sounded quite
neat. Anyone know more details?  maybe this could appear in
s.v-w.apps?

Will everyone who plans to attend the VRASP Chat in New Brunswick
On Tuesday (the 29th) please raise your hand...I would like to show
up, but I don't want to drive 4 hours to have lunch with "All the greatest
minds of Virtual Reality" and end up eating alone!

Thanx!

P.S. Start thinking about how we're going to torment the employees...
does anybody have a 486 laptop? I'll bring the Power Glove!
