Cheap and easy to use eye tracking can be used to turn a common
display into a gaze-contingent display: a system that can react to the
user’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 perceptual
insights and the knowledge about what is currently seen. This thesis
investigates how GCDs can be used to support aspects of depth and
colour perception.
This thesis presents experiments that investigate the effects of simulated
depth of field and chromatic aberration on depth perception. It
also investigates how changing the colours surrounding the attended area
can be used to influence the perceived colour and how this can be used
to increase colour differentiation of colour and potentially increase the
perceived gamut of the display.
The presented investigations and empirical results lay the foundation
for 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 tasks
that are related to visual perception. The presented techniques could be
used to facilitate common tasks like distinguishing the depth of objects
in virtual environments or discriminating similar colours in information
