Summary on Grant Application Form |

Schemata are knowledge structures based on past experience. When participants are exposed to a large amount of information in a scene, cognitive psychologists have suggested that schemata are used to guide the search for information in memory.The appeal of schemata to our goal of establishing a new and generic Virtual Environment (VE) fidelity metric is that it establishes the degree to which the appropriate schema has been activated in the real scene and its VE equivalent. The higher the similarity between the two schemata, the higher the fidelity of the VE. We propose to test these ideas in a synthetic space of varied rendering quality. The results obtained in these experiments will be used to target graphics resources in a demonstrably efficient manner - an object-based rendering engine is going to be implemented which will incorporate more detail according to the degree of association of an object with the schema in context. We are going to validate this system, psychophysically, in comparison to a fully-fledged rendering solution. The major deliverable on this work is a technique which assesses functional realism in an entirely novel way, and can lead to an efficient use of graphics resources by rendering only those objects to a high level which require detailed inspection, and vice versa.
