A friend of mine working at SAIC in San Diego is curious to know what
Stanford Research International (SRI) is up to.  He has heard of
something called the "Green Project", and thinks it might be VR
research related to medicine.  The name "Green Project" strikes a few
bells in my head, but I sure can't remember what it is.
  
Does anyone know what the "Green Project" is or, barring that, what
SRI is doing these days with respect to VR research?

Many thanks,
     ---Mark

During last SMAU fair in Milan, Italy (oct 92), an italian VR company,
ARS, has projected a whole Sense8 navigation on the screen of the
conference hall.  At least 200-300 people were in the hall. They
didn't use lc shutters, but polarized lens. The effect was quite good,
expecially if you were in front of the screen. The screen itself was
VERY big, several meters.

The CAVE system, presented during last SIGGRAPH, uses lc shutter glasses (I
think CrystalEyes) and retro-projected walls to immerse the user in a 
virtual environment.

Dean Rubine's 2D online gesture recognition papers and software are
available via anonymous FTP from emsworth.andrew.cmu.edu (128.2.30.62)
in the "gestures" directory. Five PostScript files and a README of the
paper "Specifying Gestures by Example" from SIGGRAPH 91 is in
"gestures/papers".

Also, the entire directory, including the paper, the gesture
recognizer, some NeXT code with what I assume is a GUI interface of
some sort, and general recognition software is in the compressed tar
file

         "gestures/gesture.tar.Z"

David Sturman's thesis "Whole-Hand Input", which extends Rubine's 2D
gesture recognition approach to 3D, is now available on ftp. Here is a
message he sent to me about it:

 I have put a copy of my thesis on media-lab for anonymous ftp.
 So far, I have only installed a .dvi file which can be converted to
 a Postscript file with dvips.  The dvi file is a lot smaller than the
 Postscript file and you can control which pages you want printed out.
 Again for size reasons, the available version is without the
 illustrations.  In the future I will make a more complete version
 available.

 Interested parties should anonymous ftp to media-lab.media.mit.edu and cd
 to tmp/djs/WholeHandInput.  They should read the README file before trying
 to print the thesis.

Toys does have a couple of scenes with a VR-like toy, but it is a
minor part of the movie.  There are other concepts related to VR that
play a more prominent role, but saying anything more might be a
"spoiler" for the movie.

I enjoyed Toys very much, but it's not a "VR movie" in the sense that
Lawnmower Man was.  Williams said in a promotional interview that the
VR-like toy was in the script many years ago (apparently this movie
has been kicking around for 12 years before getting made), before VR
was known to the general public.

Has anyone hacked around with the Nintendo "Freedom Connection"
wireless controller (this is a very popular surplus item)? Or How
about the Konami Laserscope?  I need to know how the Nintendo Light
pistol works. I've wired the Konami headset into the parallel port of
my PC and it recognizes my voice, but I'm not sure how to get the
photocell to respond. 

For those of you who don't know what the Laserscope is:

It's a pair of headphones with a microphone extending out to the mouth
and a nice heads-up crosshair display aligned with the photocell
(which hangs out from above).  I'm seeing these things sell all over
for about $10.  They seem to be reduced from $50, so they obviously
aren't popular among nintendo players, but it seems like a nice piece
of gear to add to the rest of the VR junk.

"The Walkman Was Primitive By Comparison

It may look like a weird pair of wraparound sunglasses, but the new
Sony Visrotron has nothing to do with observing one's surroundings. On
the contrary. Two tiny video screens (one in front of each eye) and a
miniature videotape player provide the equivalent of a personal movie
theater. Sony says a few hours of viewing do no harm to the user's
eyes.  The company hopes to market the device to airlines. First class
of course."

I recently purchased a Konami LaserScope accessory (made for
Nintendo).  I have it wired into the parallel port similar to the
PowerGlove, except that there are only 4 wires coming out of the
headset. For those of you that aren't familiar with this toy, it is a
pair of bulky plastic headphones with a microphone and a photocell
sensor (like the one used in the "Duck Hunt" pistol).  It has a nice
heads-up crosshair display. Anything spoken into the microphone
triggers the thing to fire.

I'm looking for the specs on the Headset or Pistol (I assume that they
are the same). I assume that the "latch" wire is the one missing from
the headset (as compared to the powerglove), which means that there is
a ground, +5v, clock, and data out. I can get the thing to register a
"fire", but I'm not sure how the photosensor is integrated into all of
this.

  I'm hoping to be able to use this in video games or light pen type
applications.  I highly recommend grabbing one or two of these from
your local toy store if you find them for under $15. They list for
$50, but I've been seeing them all around for a discount price of $10
-what a deal.

                "Virtual Reality and Disability"

(California State University, Northridge (CSUN).  December 15, 1992).
On December 11, twenty-five (25) leaders came together from the fields
of virtual reality and rehabilitation and assistive technology to plan
the June 17-18, 1993 meeting, "Virtual Reality and Disability," to be
held at the Westin Hotel near the San Francisco Airport.

Greenleaf Medical Systems, CyberEdge Journal, Pacific Bell, and the
California Department of Rehabilitation agreed to co-sponsor the
conference.  Dr. Walter Greenleaf has agreed to Chair the Advisory
Board.

A Call for Papers has been issued. Papers are solicited which deal
with applications in the field of disability, access issues, and the
potential of VR to assist persons with disabilities.

The purpose of the meeting is to bring together three groups: the
Virtual Reality community, the disability community, and the
rehabilitation/assistive technology community in order to stimulate
new applications of VR, insure that persons with disabilities have
access to VR technologies, and the integrate VR into the
rehabilitation/assistive technology field.

                       VIGIS-L

                A Newsgroup for those
             specifically interested in
              Virtual World Interfaces
              and their application to
           Geographic Information Systems

WHAT?! Another newsgroup??!

   Yes, yet another newsgroup to serve the ever-expanding
research/information population of the global network.

The Purpose:

   To provide a forum for issues specifically surrounding the use of
Virtual Worlds (Virtual Reality) Interfaces for Geographic Information
Systems as well as any and all spatial information/ decision support
systems. The broad goal is to generate constructive discussions about
how Virtual Worlds will be used in GIS, as well as approach the
fundamental issue of why implement VR at all.

   The discussion is wide open for topics such as: what steps to take,
where are we now, where will it go, who might benefit, what role will
conventional maps play, etc.  As with most newsgroups, the topics are
wide open.  (However, let's keep the inevitable metaphysical
discussions about the nature of reality to a minimum!  There are other
newsgroups for that...).

   In addition, it will be an open place for collaboration and the
exchanging of ideas.

The Membership:

   Anyone! From serious VR and GIS researchers to curious bystanders
from any and all disciplines.  A multi-disciplinary approach is not
only welcome, but highly encouraged.

The Moderator:

   Thomas M. Edwards, a doctoral student at the University of
Washington, Seattle and a cartographic consultant. Tom has written
three papers on the topic, including his masters thesis, and plans to
pursue it further through doctoral and personal research.

   Virtual Worlds technology has arrived and the need for improved
users interfaces in GIS has been realized. How will the disciplines
involved with VR and GIS shape their ultimate synthesis?  Be a part of
a beginning and help shape that future.

Note: This is a fledgling newsgroup and will take time to get moving.
Any 'starter' commentaries are more than welcome. This is primarily an
initial call for membership. The group should get moving with
moderator-induced info. after 1/1/93. Please be patient! Thanks...

Hi folks!
Now here is the ONLY answer I got.
so THANK YOU George Ludwig AGAIN!
Here's what he wrote:

Peter:

As has been posted, you can get the Toshiba glasses from Real 3-D.
They are definately compatible with the Sega glasses. However, when
you buy the Sega glasses you get the interface card which is what
people usually hack to make the interface to the PC (or whatever). The
Toshiba glasses do not come with an interface, but if you have a Sega
compatible interface the Toshiba glasses plug right into it, no
adapter required or anything. If the PGSI ever materializes (jab jab
Mr. Brain) the Toshiba glasses should plug right in.

The Toshiba glasses are of clearly higher quality construction. My
Sega glasses frame broke when dropped from 3 feet onto a carpeted
floor. This would be extremely unlikely with the Toshiba glasses. The
image quality of the Toshiba glasses is not, IMHO, much (any) better
than the image quality of the Sega unit. The glasses do not go even
close to entirely opaque. 

In any event, I highly reccomend the Toshiba glasses. They are cool
matte black finish and fairly durable. They look more like tools than
the Sega glasses which all too clearly resemble what they are...kid's
toys.

BTW, the cost from Real 3-d including shipping was like $80.

This is in reply to a question from John Rickert, who asked for solutions 
to Diophantine equation 19 u^3 - 18 v^3 = 1 and similar equations.  

See Theorem 6, page 225, "Diophantine Equations," by L. J. Mordell.  This 
states (among other things) that the equations a x^3 + b y^3 = 1 have AT 
MOST ONE SOLUTION.  Since with a = 19 and b = 18 we have the solution 
x = u = 1, y = -v = -1, this solution is the only one.

Howdy!

Someone recently brought me a problem concerning an error-detecting weighted
code with a modulo 11 checksum that she's using in her business. 

In short, a bunch of items are given 10 digit identification numbers. 
Let N_i denote the ith digit of the number.
Each number has the property that SUM(A_i * N_i) is congruent to 0 mod 11,
where {A_i} are weights as follows: {1, 2, 5, 3, 6, 4, 8, 7, 10, 9}.

The obvious advantages of this identification system are that no single
digit errors in a valid number and no single transposition of digits in
a valid number will produce another valid number. 

Question: What is the advantage of the weights being mixed up like that?
(i.e. why isn't A_i just set equal to i?)
References about this particular system would be the most appreciated because 
I know this weighting must have been written about somewhere. I just can't
find it.

Clearly your fellow worker was merely imagining some distinction that
very few mathematicians know or care about.  He sounds like the kind of
student who says on my teaching evaluations that I don't know the
material, typically because I prefer to rederive some trig identities instead
of memorizing them.
