 Within this Bachelor Thesis a VR-Application will be implemented and evaluated to analyze the impact of interactivity on the emergence and duration of emotions. Virtual Reality as a so-called „Mood Induction Procedure“ (VR-MIP) is considered an effective method to induce certain moods – for example relaxation. Interactivity is one of the most important factors to enhance the player experience in games. It has been shown that the possibility to interact positively affects the player’s mood – especially in terms of enjoyment and relaxation. Therefore, interactivity also might play an important role in connection with VR-MIP.
A natural virtual environment will be examined in a study (N = 50) regarding mood induction, relaxation and interactivity. Within the context of a „Seated Experience“ (8 – 10 min) relaxation should be evoked through two different versions. The first version solely contains a non- interactive environment, whereas the second version additionally provides an interactive game.
By means of several questionnaires and physiological measurements (e.g. HRV), it will be investigated whether or not the application is perceived to be relaxing and to what extent interactivity might function as a supporting element. Subsequently, the question how long the induced mood lasts and if relaxation can be transferred to a stressful situation – brought about by a VR-TSST – will be tested. VR-MIP are often used as a therapeutic tool for inducing specific moods (e.g. relaxation or happiness) in people who need mood modification. Thus, it is of great importance to expand knowledge concerning an effective and lasting stress reduction.
