The study of reward system affect the motivation of elderly player in virtual reality serious game

Abstract

In this research, we explore reward systems consisting of badge and point systems that impacted intrinsic motivation between elderly and adult participants in a virtual reality exergame. This research used quantitative methods that analyzed the effects of intrinsic motivation within reward systems between two groups. In this way, we measure intrinsic motivation by the Intrinsic Motivation Inventory (IMI) during the experimental study. Also, we recruited forty participants for the study, both adult and elderly participants, with twenty participants for each group. The primary source of elderly participants was aged 61 to 68, and the adult was aged 18 to 24. The results show that participants between elderly and adults impacted the different levels of intrinsic motivation for each reward system using the Mann-Whitney U test in virtual reality exergame. The badge system impacts the levels of intrinsic motivation, including Enjoyment, Effort, Tension, and Value subscale. However, in the experiment, the point system impacted intrinsic motivation, including enjoyment, Tension, and Value subscale. Surprisingly, after analyzing, we found additional findings in this research showed that the different levels of intrinsic motivation were related to the user experience within reward systems that used spearman's rank correlation coefficient by the primary source of participants. The badge system has impacted levels of intrinsic motivation related to user experience. However, the scoring system has impacted different levels of intrinsic motivation, but it was unrelated to the participant user experience. Therefore, we suggest future studies that Tension parameters in IMI could explore with Heart rate variability or a Perceived Stress Questionnaire (PSQ).
