COllaborative Virtual ENvironments
by Lennart Fahlén
COVEN (COllaborative Virtual
ENvironments)aims at developing a computational service for teleworking
and virtual presence. The overall objective of the project is to provide
the facilities needed to support future cooperative teleworking systems
and to demonstrate the added value of networked VR for both professional
users and home users.
COVEN is a project of the European Union Advanced Communications Technologies
and Services Programme, in the Fourth Framework Programme of research
and development (1994-1998). COVEN is a 4-year project starting 1 October
1995.
COVEN aims at developing a computational service for teleworking and
virtual presence. The overall objective of the project is to provide the
facilities needed to support future cooperative teleworking systems and
to demonstrate the added value of networked virtual reality for both professional
users and home users.
COVEN will develop a general platform for Collaborative Virtual Environments
(CVEs), providing the application-level facilities needed to support the
implementation of these CVEs. The development of the COVEN platform will
be driven by the needs of two CVE applications: a business-oriented 'Arena
Tool' application and a citizen-oriented 'Travel arrangement' application
.
COVEN is a unique project which brings together a wide range of expertise
on communication infrastructures, CSCW, Virtual Environments, Human-Computer
Interaction and VR animation to provide support for a European distributed
virtual environment. Target key issues are collaboration support within
VEs (including awareness, communication, group interaction, etc.), corresponding
requirements at network and platform level (involving concern for scalability
and continuous media support), and related Human Factors aspects. Key issues
are also the evolution and contribution to current standardisation efforts
(DIS, VRML, MPEG4).
COVEN will carry out networking trials of its platform over ISDN and
over ATM, using National Hosts of at least four European countries. The
COVEN applications will encompass both the high-end and low-end of the
spectrum of VR applications.
Expected Impact
The development of an integrated COVEN platform, based on Division Ltd's
dVS, will maintain a strong European presence in the future of the VE marketplace.
The objective of the project is also to strengthen European involvement
in key international standards.
Work
The project builds upon a set of existing platforms and experiences
which result from field trials across a range of different networks. Our
technical approach centres on three cycles of design, development, experimentation
and dissemination. The work is defined as height workpackages, each of
which runs through three iterations across the four years of the project.
Develop a powerful networked VR platform based on dVS, an existing commercial
VR platform from Division Ltd. Developments will be fed by the exploratory
prototyping experiences gained using the DIVE research platform of the
Swedish Institute of Computer Science.
Summary of Trial
COVEN networking trials will be based on an enhanced version of the
commercially available European VR platform dVS, and four National Hosts:
SuperJANET (UK), ForthNET (GR), the Royal PTT Netherlands host (NL) and
the French National Host through CNET (F).
The networking trials will be carried out in four distinct phases, based
on different versions of the Demonstrators, making an extensive use of
ISDN in all phases and introducing ATM in phases 3 and 4. The trials (in
particular the ATM trials) will be organized around two clusters of linked
sites, one within the UK and another between France and The Netherlands.
At each trial phase, both an assessment of network performances and a Human
Factors evaluation will be performed.
