· develop careful design methodologies to determine user requirements, based on a human-centred, "constructivist" approach to working and learning, with special attention paid to evaluation of the resulting mixed reality experience.

· adapt, develop, and combine novel visualisation, display and audio technologies based on the requirements thus defined, to enable realism with interactivity, specifically for immersive VR platforms (single/multiple-screen stereoscopic displays).

· construct prototypes for two specific applications, cultural heritage and architecture/urban planning, that incorporate more natural and usable interface approaches and permit assessment of both the methodology and technology employed.
