  This paper proposes a set of techniques to investigate eye gaze and fixation
patterns while users interact with electronic user interfaces. In particular,
two case studies are presented - one on analysing eye gaze while interacting
with deceptive materials in web pages and another on analysing graphs in
standard computer monitor and virtual reality displays. We analysed spatial and
temporal distributions of eye gaze fixations and sequence of eye gaze
movements. We used this information to propose new design guidelines to avoid
deceptive materials in web and user-friendly representation of data in 2D
graphs. In 2D graph study we identified that area graph has lowest number of
clusters for user's gaze fixations and lowest average response time. The
results of 2D graph study were implemented in virtual and mixed reality
environment. Along with this, it was ob-served that the duration while
interacting with deceptive materials in web pages is independent of the number
of fixations. Furthermore, web-based data visualization tool for analysing eye
tracking data from single and multiple users was developed.
