Abstract

The complexity of software projects is increasing and so is the difficulty of understanding
them. Modern software visualization software can be used to support this understanding.
It makes it possible to comprehend software not only at a code level, but with the help
of visual illustrations. Due to technological progress, software landscapes today can not
only be viewed visually on a monitor. The state-of-the-art technology called virtual reality
offers a different and immersive experience. It allows users to dive into the software using
devices such as the Oculus Rift or HTC Vive.
This thesis presents an approach that allows the exploration of software landscapes in
virtual reality collaboratively. The software visualization tool ExplorViz is extended for
this purpose. The existing VR plugin is further developed and a multi-user functionality
is realized with the help of WebSocket connections. Since software is usually developed
in a team, members of a team can come together in the virtual world. To the best of our
knowledge, there is no comparable approach at this time.
Through an evaluation we verified the usability of our approach. For this 11 groups
with 2 persons each tested and rated our collaborative VR approach. The results indicate a
positive experience and good usability. Especially well rated was the impression that the
participants felt to be in the same virtual world.
