Abstract:In this thesis we want to investigate if it is useful to control physiological measures during a serious game in real-time. The reason for this is that the external stakeholder, T-Xchange, hopes that they can adapt a serious game based on the arousal of the players. To study this we used one slow and one fast version of a game and looked at EDA, HR, and HRV for an indication about the physiological arousal. A survey was also used to test the subjective stress of the participants. It was expected that the fast version of the game would elicit more physiological arousal than the slow version. 43 participants, randomly divided over the two versions, participated in this experiment. The differences between the two versions were tested. It was also tested if the physiological measures correlated with each other and if the self-reports correlated with these physiological measures. No significant differences in the EDA and HRV were found. However, the HR in the baseline was significantly higher than during the game and the HR in the slow version was higher than in the fast version. Furthermore, no correlations between the physiological measures were found. No relations were found between the self-reports and physiological measures either. It can be concluded that real-time information about physiological arousal has to be interpreted with caution. We recommend T-Xchange to not adapt their game based on physiological measures, but use a serious game that has some short movies in it that will make the player feel like he or she is participating in a realistic experience. This will increase the transfer of learned information and players will use this information better in real situations.
