CRG Research Technology Pushes

Our research is driven both by technology push (general underlying techniques and concepts) and application pull (the application of these techniques to particular problems). These define a matrix of active research issues.

Large-Scale Dynamic Network Architectures

Supporting very large numbers of participants, dynamic session control and QoS management, spatially scoped hierarchical multicasting, traffic modelling and analysis.

Mixed Realities

New forms of interface based on transparent boundaries between physical and virtual worlds - group interaction with shared displays.

The Spatial Model

Mechanisms whereby participants, application developers and system managers can easily understand and manipulate complex network characteristics (e.g. using the spatial model to control QoS). Understanding social phenomena in CVEs through field trials, informing the design of CVEs, developing new methodologies.

Crowds and Aggregations

Supporting dynamic aggregation mechanisms at both the perceptual and network levels (e.g. crowds, data districts etc.).

Work and Social Interaction through CVEs

Supporting participants abilities to communicate using features of CVE worlds to enable and support work and interaction.

Information Visualisation

Scaleable techniques for visualisation and interacting with large-datasets and for tracking and representing the presence and activities of other users.

Wayfinding and Navigation

Urban planning, wayfinding and navigation for virtual environments.

Methodology of Usability Evaluation for Collaborative Virtual Environments
