Abstract

Software was never more complex then today. To improve program comprehension, several
visualization tools and techniques are researched. The web-based tool ExplorViz helps
developers to achieve an understanding of large software landscapes more easily than
looking at source code. The communication of the landscape is visualized with live traces
[Fittkau et al. 2013].
To improve a software development process and product, according to [Basili et al.
1986], are experiments necessary. Further, they help to understand, evaluate and control the
process and product. Thus, the improvement to conduct experiments will help to improve a
product. And in modern society and technology, it was never easier or cheaper than today
to track the user’s gaze. And to understand and enhance human computer interaction is
an asset to be pursued.
In this thesis we present an approach to improve the optional ExplorViz experiment
mode, which can create and manage questionnaires to conduct interactive experiments in
ExplorViz. The approach improves the usability and enhances the experiment mode with
the feature of eye tracking and recording the screen during an experiment. Further, we
evaluate the approach with an experiment and confirm its functionality. The eye tracking
data results do not display immediate correlations, but the data is versatile and useful.
