Research Interests: Summary
The aim of my work is to describe, identify, and support the concept of minimal perceptual cues for the benefit of Immersive Virtual Environment (IVE) design and application. The scope of this work is limited to consider visual perceptual cues only. The work will be carried out via the construction of a methodical and principled technique that shall be used to determine the required perceptual cues needed to represent a particular type of environment (for instance, a kitchen, or office.) In practice this will entail the measurement of the sense of presence in a particular type of environment, whilst the level of detail is increased until a presence threshold is reached. The identification of minimal cues will be useful for the construction of future IVEs as they can then be created objectively, consistently, and with minimal effort and computation. The evidence to support the results is determined using a novel objective measure of presence that should prove useful in its own right. At the moment, there is no objective measure that can be consistently applied to a wide range of environments, and this approach should prove to be a useful tool for future IVE work in general. The sense of presence will be estimated using a modification of Stark's scanpath theory by considering eye gaze (foveations) and movements (saccades) in IVEs rather than those directed at two or three-dimensional images. |
