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.
