【 摘 要 】

Cheap and easy to use eye tracking can be used to turn a commondisplay into a gaze-contingent display: a system that can react to theuser’s gaze and adjust its content based on where an observer is looking.This can be used to enhance the rendering on screens based on perceptualinsights and the knowledge about what is currently seen. This thesisinvestigates how GCDs can be used to support aspects of depth andcolour perception.This thesis presents experiments that investigate the effects of simulateddepth of field and chromatic aberration on depth perception. Italso investigates how changing the colours surrounding the attended areacan be used to influence the perceived colour and how this can be usedto increase colour differentiation of colour and potentially increase theperceived gamut of the display.The presented investigations and empirical results lay the foundationfor future investigations and development of gaze-contingent technologies,as well as for general applications of colour and depth perception.The results show that GCDs can be used to support the user in tasksthat are related to visual perception. The presented techniques could beused to facilitate common tasks like distinguishing the depth of objectsin virtual environments or discriminating similar colours in informationvisualisations.
