### 1.1 History ######################################################

        Sci.Virtual-Worlds was created early in 1990, as a result of
Howard Rheingold's efforts to gather research material for his book:
"Virtual Reality" [see section 3.4.1].  In the beginning, Rheingold
envisioned sci.virtual-worlds as a

        ...scientific newsgroup for discussing research and
        development in virtual reality on a less formal, more
        frequent, more highly distributed basis than the welter of
        professional organizations, conventions, conferences, and
        journals that served as communication media for the individual
        disciplines that were converging on VR.
        [199-200, Chapter 9: Reality on Your Retina, "Virtual Reality"]

        Since Rheingold did not possess sufficient resources to
moderate and archive such a group, he sent e-mail to Thomas A. Furness
III, the Human Interface Technology Laboratory (HITLab) director,
outlining his proposal.  The next day he received a response:

        Furness was in favor of the idea.  Indeed, one of his goals
        for the HIT Lab was to make research information as widely
        available as possible to VR researchers.  Sponsoring a
        worldwide newsgroup would be a first step.  An on-line
        bibliographic data base that could be searched by interested
        parties through the network could be a future improvement.
        [200, Chapter 9: Reality on Your Retina, "Virtual Reality"]

        Upon completion of his book, Rheingold yielded the newsgroup
reigns to Steve Aukstakalnis, who in turn yielded them to a HITLab
administrator, Robert "Bob" Jacobson.  Bob enlisted the assistance of
Mark DeLoura, a HITLab undergraduate, to take charge of the archive
and FAQ construction.  Eventually, Bob went on to create WorlDesign
Inc. in Seattle, while Mark moved to the University of North Carolina
at Chapel Hill to study as a graduate student.  Together, however,
they founded sci.virtual-worlds.apps.  An in-depth reflection on the
history of sci.virtual-worlds, by Mark DeLoura, can be found in the
HITLab Knowledge Base:
        /public/virtual-worlds/faq/other/scivw-history.part1

        Sci.virtual-worlds.apps was created as a spin-off of
sci.virtual-worlds, "...for the discussion of pending and actual
applications of virtual worlds technology in industrial, commercial,
educational, and entertainment settings" [Bob Jacobson, RFD for
sci.virtual-worlds.apps].  Sci.virtual-worlds remains the general
forum for discussing software/hardware development, interface design,
related conferences/events, philisophical issues, emerging standards,
etc.

        The current Scivw Moderating Group contains seven members of
the HITLab team (a balance of staff and students) led by the Research
Librarian, Toni Emerson: Michael "Squish" Almquist, Daniel Pirone,
Jerry Prothero, Aaron Kaleva Pulkka, T.M. Ramstad, and Mark Takacs.
The final member of the group, Gregory B. Newby at UIUC, has been
maintaining the newsgroup's email redistribution list since 1991.
Toni, Aaron, and Squish perform the traditional moderation tasks of
administrating, posting, and archiving.  The balance of the moderating
group act as consultants: managing quality, gathering information, and
providing technical support.  The group meets weekly to discuss trends
on the newsgroup, both in terms of form and content.


### 1.2 Biographies ##################################################

MICHAEL ALMQUIST <squish@hitl>; - Michael Almquist (aka. "squish") has

             ###            Posting Policy           ###
             ###########################################


### 2.1 Editing ######################################################

        We will not edit portions of submissions to correct spelling,
grammar, or content.

        In order to make articles and subsequent quotations more
readable, we may reformat them so that each line contains less than 71
characters and ends with a carriage-return/line-feed [you can save us
some time by doing this before submitting].

        Oversized signatures may be truncated [please respect the
general Usenet guideline of 4 lines, maximum].

        We may edit the subject-line for clarity and consistency [see
section 2.4].

        We may edit the comment portion of followups to previous
postings, if it is too long or not pertinent to the reply.


### 2.2 Rejecting ####################################################

        Although we expect most submissions will be posted, we do have
certain guidelines by which we will reject articles.

We will not post:
        - articles that are not coherently related to virtual worlds,
        - flames (any posting that directly attacks person and/or idea
          without objective, analytical content), or
        - comments directed to the moderators (unless of general
          interest).

        If we receive multiple submissions expressing essentially the
same idea, we may only post one.

        ANYTIME we decide not to post a submission, we will send a
message to the author indicating why it is not being posted.


### 2.3 Cross-posting ################################################

        We do not allow cross-posting between sci.virtual-worlds and
other moderated newsgroups, unless the articles are submitted
separately (this is due to a limitation in the way the Usenet handles
moderated newsgroups).  Moreover, there is no need to cross-post
between sci.v-w and sci.v-w.apps, since these newsgroups have
different focal points.

        We do not allow re-posting of copyrighted material (such as
articles from the ClariNet News Services) without proper permission.
You may, however, submit a summary of, review of, or pointer to such
material -- or contact the author and request that they post directly
to sci.virtual-worlds.  Since we are unable to check the copyright
authority of each submission, we rely on you to use good judgement
when posting.

        SUGGESTION:     A suggestion for how things "should" be done.


### 2.5 Digests ######################################################

        The three digests, "Virtual Interface Marketplace,"
"Virtual-worlds Info Booth," and "Scivw Request," are weekly posts
containing a collection of related messages (posted Monday, Wednesday,
and Friday, respectively).  Since we will not post empty digests, a
skipped issue indicates that we received no relevant submissions that
week.

        The first part of each digest will include a list of the
subject lines from the posts contained in the digest, allowing for a
quick check to see if the digest contains anything of specific
interest to you.

        These digests may be plodded through on your newsreader or you
may use your mailreader to read each message in the digest separately
(assuming your mailreader can read folders in 'mailbox format').
Reading a digest in mailbox format requires these simple steps:

>From your newsreader:
         - save the digest to a file,
Using your string replacement tool (like a text editor):
         - replace all strings ">From " with "From "
           (between, not including, the quotes; the spaces
            are important),
>From your mailreader:
         - open the file as a folder.

        Now the individual posts will appear as if they are separate
mail messages, and can be treated as such.  The subject lines will
coincide with those on the posts and can be used to determine which
ones to delete and which ones to read.

To respond to an author directly:
        reply as you would with e-mail
        (be sure the "To: " header is appropriate).
To post a follow-up:
        change the "To: " header in your reply, replacing the
        author's address with "scivw@hitl.washington.edu";
        Do NOT follow-up to the entire digest as one message.

             ###               Glossary              ###
             ###########################################


### 4.1 General ######################################################

        Many of the terms listed in this glossary do not have a
single, universally accepted definition.  The definitions listed below
have been compiled from years of discussions and borrowed from other
glossaries.

        "Virtual Reality Terms" (1993), compiled by Joe Psotka and
Sharon Davison, can be found in the HITLab Knowledge Base:
        /public/virtual-worlds/faq/other/VR-glossary

        Another useful collection of definitions, called the "Virtual
Reality Glossary" (July 1992), was compiled by L. Jacobson for the
Virtual Reality Special Report of AI Expert [see section 3.3.2].

### Artificial Reality:
This term was coined by Myron Krueger in the mid-1970s to describe his
non-immersive "computer-controlled responsive environments."  The full
body motion of the participant effects the computer generated
environment, displayed on a screen.  For more information, see
"Artificial Reality II" (1991).

### Augmented Reality:
The use of transparent HMDs to overlay computer generated images onto
the physical environment.  Precisely calibrated, rapid head tracking
is required to maintain cohesion.

### Cyberspace:
This term was originally coined by William Gibson, in "Neuromancer"
[see section 3.4.3], to describe the shared virtual universe of the
world's computer networks, where both participants and data could be
seen, heard, and touched.  This term has come to describe the more
familiar global information space.  Our telephone conversations,
Usenet discussions, and ATM transactions all take place in cyberspace.

### MUD:
Multiple User {Domain, Dungeon, or Dialogue}.  These are typically
text-based environments which allow many users to communicate and
build worlds in "real-time."  There are many different types of MUDs:
discussion, fantasy adventure, science-fiction adventure, and others.
        For more information, consult the three-part FAQ on Muds and
Mudding in the HITLab Knowledge Base:
        /public/virtual-worlds/faq/other/FAQ_mud.{1, 2, or 3}

### Presence:
The feeling of actually being in an environment, whether it is real,
augmented, or virtual.  This is a defining characteristic of an
immersive VR system.

### Projected Reality:
A computer system which uses projection televisions to provide an
individual or group with windows to a virtual environment.

### Teleoperation:
The remote operation of a robotic system.  If the human interface
provides an immersive environment, then it can also be called
"telepresence."

### Virtual Reality (VR):
This term is attributed to Jaron Lanier, to describe an immersive,
interactive simulation of realistic or imaginary scenes.  Common usage
of this term would indicate that the immersive component is not
required.  However, many researchers strongly believe that immersion
is as important as interactivity.

### Virtual World:
A 3d model of an environment comprised of a set of objects or
entities, which can be experienced as a virtual reality.


### 4.2 Technical ####################################################

### 6d or 6dof:
Six degrees of freedom can be specified as: pan, zoom, swivel, pitch,
roll, and yaw.

### BSX:
Bram Stolk's X-windows based graphical MUD system.  Regenesis, built
using the BSX system, was the first publically accessible MUD on the
internet to combine combine text and 2d color graphics.

### CyberMan:
A 6d stationary input device made by Logitech.  This device measures
only the direction a force is applied, not the magnitude.

### DataGlove:
A gesture recognition device developed by VPL Research.  Magnitude of
finger flexation is determined by measuring the amount of light that
escapes from the scratched surface of a fiber optic strand in each
finger. Position and orientation of the hand is determined by an
external sensor, such as the Polhemus.

### HMD:
A Head mounted display strictly refers to a graphical display device,
although it is usually coupled with position tracking and earphones
for 3d sound.

### PGSI:
The PowerGlove Serial Interface provides users the ability to connect
their glove to any personal computer.

### Polhemus:
A sensor device which uses electromagnetic coils to provide a 6d
position and orientation measurement.

### PowerGlove:
Gesture recognition device developed for the Nintendo Entertainment
System by Abrahms/Gentile Entertainment and licensed to Mattel Toys
(out of production).  Magnitude of finger flexation is determined by
measuring the change in resistance of a piezioelectric strip in each
finger.  Position and orientation of the hand are measured by built-in
ultrasonic sensors.

### REND 386:
A real-time polygon renderer for Intel 386s and up.  Used in
combination with a 3d display device, such as Shutter Glasses, and a
3d input device, such as the PowerGlove, hackers can create virtual
environments at home.

### Shutter Glasses:
Liquid crystal glasses which cover each eye alternatively, in sync
with the alternating display of images for each eye, produce a 3d
effect.

### Spaceball:
A 6d stationary input device which measures both magnitude and
direction of an applied force.

### VEOS:
The Virtual Environment Operating {System, Shell} was developed at the
HITLab as a foundation for building distributed virtual worlds.

### VRD:
The Virtual Retinal Display, developed at the HITLab, is a display
approach wherein lasers are used to scan images directly onto the
retina.  This has the potential of greatly reducing the size, weight,
and power consumption of displays, while increasing the resolution.


### 4.3 Others #######################################################

### CAVE:
An interface characterized by projection devices on the walls used to
facilitate immersion, such as the CAVE "virtual reality theater" in
the Electronic Visualization Laboratory at the University of Illinois
at Chicago.

### HITLab or HITL:
Human Interace Technology Laboratory in Seattle, Washington.

### UIUC:
University of Illinois at Urbana Champaign.

### UNC-CH:
University of North Carolina at Chapel Hill.

### 5.1 HITLab Knowledge Base ########################################

        The HITLab Knowledge Base is currently accessible by anonymous
ftp (use the login name "anonymous" and use your email address as the
password) at:
        ftp.u.washington.edu
        [140.142.56.2]

There are two public hierarchies at that site, that are maintained as
part of the HITLab Knowledge Base project:
        /public/virtual-worlds/
        /public/VirtualReality/

        The first, /public/virtual-worlds/, has been maintained by Bob
Jacobson of WorlDesign and Mark A. DeLoura of the University of North
Carolina, Chapel Hill.  Many thanks for their efforts.  This archive
is now being reconstructed by the new Scivw Moderating Group (Toni
Emerson, Aaron Pulkka, et al.).  Much of the information in this area
is out of date, please contact us with corrections.  The contents and
organization of this archive will be changing on a daily basis, please
forgive us for any inconvenience this may cause.

Current contents of /public/virtual-worlds/:
