Abstract:

Virtual reality (VR) has become available for many end users and brings along diverse opportunities for serious game applications, such as exergaming, a combination of physical exercise and gaming. Depending on the exercise type, instructions may be necessary to perform the task correctly, in VR e.g. via the visual channel. Within the present thesis, a VR rowing simulation has been extended by visualizations displaying respiratory biofeedback for helping rowers to breath properly during exercise. Interface elements include a lung animation, a line chart and numerical as well as textual respiratory task performance feedback. For the underlying study, a within-subject design has been chosen to examine the impacts of breathing feedback on correct breathing performance as well as on flow, measured with the S FSS-2, and overall perceived presence. Furthermore, the virtual environment has been evaluated with the AttrakDiff-Short to gain information about attractiveness, hedonic and pragmatic quality. Even though the data analysis showed no significant differences between the experiment conditions regarding correct breathing, all feedback conditions received a significantly higher helpfulness rank than the non-feedback conditions. Flow is rated significantly higher for the condition with all feedback types compared to the condition outside VR. Moreover, significant positive relationships were found for mood with task performance and mood with self-perception of performance. Implications for further studies and potential improvements for breathing instructions in VR rowing simulations are discussed. ​
