Our base s/w is fully distributed & networkable. We have demonstrated
(with ease) 3 and 4 user systems using local transputer links, and we've
done similar sizes on ethernet.
The BT project we're working on is looking at similar issue across
wide area nets.

Subject: Press Release from Division Limited about VIRTUOSI project
Contact: Pierre duPont +44 (0)454 615554
VIRTUOSI - Support for Virtual Organisations
Bristol, UK - 15 February 1994 - The UK Department of Trade and
Industry (DTI) has today announced funding for the VIRTUOSI project,
a consortium of UK industrial and academic partners which will
explore the use of virtual reality to allow multiple users to perform
simultaneous, co-operative work across geographically dispersed
locations. This project, part of the DTI/SERC Computer Supported
Co-operative Work (CSCW) programme, has a total budget of
approximately u2.5m over three years, with a DTI/SERC contribution
of about u1m.
Virtuosi will allow people to join discussions and problem-solving
activities at home or in different offices or factories across the world.
Virtual reality technology from the UK company, Division Ltd, will
contribute to the core framework of the project, providing powerful
tools to allow users to interact within the virtual environment.
A strong theoretical basis will be provided for the project by
Nottingham, Lancaster and Manchester Universities. These
Universities are all involved in UK and European research projects to
establish the fundamental principles for interacting and co-operating
in virtual environments that will be set up across future information
superhighways. In addition to developing models and systems, they
will also be involved in capturing user requirements and assessing
the effectiveness of the two application pilots.
Two pilot applications will be developed by the project. One will be
concerned with improving communication between a number of BICC
Cable factories throughout the world. The aim is to enable managers
and workers to share expertise as easily as if they were in a single
factory. For example, technical experts on one continent will be able
to "visit" shopfloor staff on another continent to co-operate on
resolving technical and production issues at the remote factory.
A compact 3D representation of the total organisation will be
generated on the screen of the desktop computer. Users will be able
to move round this visualisation to locate individuals and sources of
expertise at the remote sites. The system will then integrate video
windows and computer based data into this virtual world while setting
up a conference call to the participants.
The other pilot service will be based in the textile and clothing
industry to allow co-operation between a number of small and
medium enterprises involved in the design and manufacture of
fashion garments. This application will be part of Nottinghamshire
County Council's programme to support industry in its area and to
provide competitive advantage to its users.
Designers will be able to use virtual reality techniques to create a
visualisation of a garment. The designer will be able to discuss the
design with remote buyers who will also be able to see the garment
being worn by a model on a 'virtual catwalk'. Users will be able to
make changes and view the effects during their discussions and,
once agreement has been reached, the details of the design will be
transferred immediately to the factory for manufacture. The work on
this application will be supported by a consultant to the project based
at Nottingham Trent University who will provide expertise on
computer support and visualisation techniques in garment design
Both BT and GPT Ltd will be involved in developing the
telecommunications aspects of the project. GPT's contribution will
also be supported by GEC Marconi Hirst Research Laboratories which
has considerable experience in virtual reality applications.
NOTES TO EDITORS: VIRTUOSI is a project within the DTI/SERC
Computer Supported Co-operative work (CSCW) programme. Its aim
is to promote research into the use of computer systems to support
groups of people working together in industry or commerce. Virtuosi
is one of eight projects selected for the programme. The total budget
for the project, which will run for three years, is in the order of u2.5m,
with a government contribution from DTI and SERC of about u1m.
The organisations that form the project consortium are British
Telecommunications plc (the lead partner on the project), BICC plc,
Division Ltd, GPT Ltd, The University of Lancaster, The University of
Manchester, and The University of Nottingham.
Note: Photographs representative of the goals of the project are
available.

Extracted from our last communication
Subject: Re: Survey on Networked VR
I'm developing a Ph.D. research about Interactive Narrations as
entertainment systems (not games in the traditional sense) in
intersemiotic, visually-based media (mainly Interactive Video). This led
me to multimedia systems in general and, of course, to VR as the
ultimate interactive pattern. The entertainment interaction that has
been developed in networked VRs (better to specify I'm talking about
MOOs and MUDs) revelead to be particularly interesting.
As I am working with Interactive Systems to entertainment, I know my
research is related to other projects from Philips. Feel free to
contact me in the address below.

My (Vassilis) reply:
>> Can you give me more details/pointers on your work?
>> Be more specific on the networked side of VR if possible.
>> By the way what's MOOs and MUDs ?
and the answer:
Dear Vassilis
Unhappilly I cannot send you many details on my work right now, as I
am in the very beginning of my research, and I have to be very carefull
about copyright matters.
The interactive artefacts I am proposing could be available through
network as well as distributed in CDs. They do not require any new
technical hardware or pattern, but the same as any interactive system
in the market. The innovations concentrate in the narrative framework I
propose. These artefacts are not Virtual Reality themselves, but lead
me to research in the field as I said before.
The concept of VR is often considered large enough to include
non-immersive systems. It depends on the definition of VR you choose
to work with.
The power of non-immersive, text-based fully-mediated VR is clear in
the uses of M**s. MOOs and MUDs are text-based virtual reality systems
that run in the Internet. I would suggest you to have a look in the URL
http://www.ccs.neu.edu/USER/lpb/muddex for a series of information
related to M**s. The enclosed article Village Voice, from Julian Dibbel,
can be a good starting point to the subject.
I also suggest you to make contact with the UK VRSIG (United Kingdom
Virtual Reality Special Interest Group), whose mail list is administered
by Sean Clark, email <S.M.Clark@lut.ac.uk . A very active member of
the UKVRSIG, Chris Hand can be someone you would like to contact as
well: <cph@dmu.ac.uk .
A previous look in Chris Hand's page in the WWW would help you to
know more about the UKVRSIG, M**s and C

Computer Science House, at the Rochester Institute of Technology, in Rochester,
NY has been working for three years on the VR: Learning Systems Development
project. It is a multi-user, distributed VR environment (Networked VR). The
project was originally implemented in C and demonstrated at the Montage trade
show in Rochester New York. Since then it has evolved to C++, and is currently
entering its third revision. Expected Beta release for the third revision
libraries is late October, with a full release early in 1995.
The system design revolves around flexibility and readibility. It will be
released into the public domain upon completion and will be compatible across
many platforms. (It is being developed on Linux PCs, VAX systems, and Sparcs).
The current implementation is sever/client based, but the upcomming revision
will include broadcast and multicasting technology.
I would appreciate a CC: of responses that you get. I am currently compiling a
distributed VR faq, and am thinking about starting a distributed VR mailing list
this fall.

Subject: TELEVIRTUALITY: Survey on Networked VR
Dear Dr. Seferidis:
Less than two weeks ago, PVN (my company) has just completed a very extensive
survey on Networked VR, i.e. the global field and emerging market of shared,
on-line 3D graphical Virtual Environments.
Think of the recent Esther Dyson Report on the subject and multiply
that by at least 20. That should give you an idea of the kind and
amount of information and insights we have compiled. I think it fair
to say that, besides being an actor in the field itself, PVN presently
is probably one of the (if not *the*) best informed and best
documented organisations around with regard to this field.
Project descriptions, contact information, software demos, elaborate
(evaluation) experience with prototypes and existing systems, videos,
still images (screen shots etc.)... You name it, we have it. (Or we
know where to get it.)
I take it that you would like to discuss how we could work together so
as to leverage this knowledge and documentation to the benefit of your
activities and plans. I think that considering the complexity of the
matter, we had better talk about this on the phone. You can reach me
from 9 am to 11 pm at number +32 14 88 18 63.

Subject: VR-Link
Vassilis,
I noticed your query about networked VR and thought you should know
about our product. We've been selling VR-Link for about 2 years, and
it's currently the most widely used simulation networking package in
the world. It also helps to be the only one available. We currently
sell mostly to the military for networked combat simulation, but we
are starting to sell into the networked VR and entertainment business
areas as well. We have several customers in the UK, as well as a
distributor (Transformation Software in Oxfordshire). You should be
able to get a demo from them or an eval copy. Contact Nick Fusco at
844-217947.
If you have any more specific questions please feel free to ask. We
also do a great deal of research in protocol extensions to DIS for VR
interactions.
