Each partner in the COVEN project has public and private pages. The central pages for the project are held at Thomson-CSF, Laboratoire Central de Recherches. These pages are Nottingham's public page. Nottingham's private pages are only available to project partners.
COVEN is a four year (1995-1999) EC ACTS funded project focusing on the development of 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. The project is a unique endeavour that brings together expertise on communications infrastructures; computer supported cooperative work; virtual reality (VR) and animation to provide support for a European wide distributed virtual environment (VE). This virtual environment will enable groups of geographically disparate users to work together by inhabiting common information spaces.
Nottingham are responsible for running the trial phase of COVEN where the applications which have been developed are used over wide area networks.
Last year saw us complete the first phase of trials using the applications developed within WP2 of the project. Five sites were involved in these initial trials, University College London, the University of Nottingham and Division Ltd in Bristol as UK representatives, and TNO-FEL in The Hague and KPN in Gronigen as Dutch representatives. The trials were run over ISDN. Both network and usability issues were examined during the trials and the results can be found in project deliverables (del3.4, del3.5).
The following Quicktime movies of the phase one trials are available:
This year, 1998, more trials will take place over a greater variety of networks, exploring issues of scale and evaluating techniques developed in the project which have been applied to the COVEN platform and applications.
Specifically there will be three sorts of trial:
We will build upon the five-site infrastructure put in place in the first trials phase and extend this to eight sites, adding Thomson, IIS and Lancaster. Information on the ISDN trials is available to project members here.
The ATM trials are being coordinated by KPN Research. Initially this involves EPFL and Geneva undertaking trials using the ATM link between Geneva and Lausanne in parallel with internal tests between different sites at KPN. After initial testing these two groups will be joined together to provide a larger test network. Provisionally SICS and UCL will join in the later stages of these trials. For more details on the ATM trials see the KPN pages.
These trials will use DIVE over the everyday networks which provide connectivity between the sites involved, Nottingham, SICS, Lancaster and UCL. In particular investigations will be made into the scaleability of the DIVE network multicast architecture. Our aim is to have 15 simultaneous, interacting, audio-aware participants in a single DIVE session. Information on the IP trials is available to project members here.
The focus of the combined usability activities is split up in three related threads, listed below. During the network trials exploratory studies of human behaviour is taking place. Results from these studies are reported on the main usability pages when they become publicly available.
Our mission statement: Since we are working in a new communication medium, we are trying to unearth CVE specific, usability and virtual environment design problems, solutions and techniques. Acceptable design solutions will have to satisfy two constraints. A human constraint: it has to be effective and intuitive, and a machine constraint: it has to utilise minimum computational load and network traffic.
