Abstract

Virtual Reality Exergaming requires, due to its high levels of activity, sufficient unobstructed space for safe use. However, enough free room is not always given, which is why a suitable and effective calibration of the given space is a particularly important prerequisite for a positive VR experience. If, despite the calibration, users are still afraid of bumping into real nearby objects, they experience collision anxiety. In this context, the aim of this bachelor thesis is to examine which factors can contribute to reducing this collision anxiety. Confidence in VR and the calibration types are the key variables. For this purpose, two calibration methods were developed and tested using a VR exergame as part of a quantitative laboratory study in a smaller room. Positive correlations were found between trust, game and calibration experience, as well as in presence. Trust and presence were the biggest influencers in reducing collision anxiety, but calibration or actual collisions were also found to be influential. The results of this study show which exact factors have an effect on collision anxiety, which can ultimately help to promote immersion and trust in virtual reality. Further research could be directed towards repeated use of exergames, in order to investigate potential learning and habituation effects.
