The VECG group's research spans the range from real-time computer graphics rendering to human factors issues in virtual reality. A common theme is that we want to understand how to make virtual reality effective. We carry out experiments with participants, in order to examine just what makes a difference to their sense of presence in the virtual environment, and their sense of co-presence with other people.

We research on the issues involved in populating our virtual environments with crowds. This is not only a technically interesting challenge, but we know from our experimental work that empty environments, places without people don't work.

We are very interested in making our virtual characters 'realistic', so that you will want to engage with them. But what does 'realistic' mean in this context? It does not mean photo or geometrically accurate realism. It does mean virtual people that carry out those tiny gestures and movements that we take so much for granted in everyday experience that we don't even notice them.
