Abstract

 Although physical activity is relevant to health, many people do not follow the minimum recommendations. Exergames are a possible motivation for more exercise. There is the challenge with a heterogeneous group of players not to physical over- or under-exert them. The heart rate can be taken as an indicator for physical exertion. In research, there are two approaches that make use of this. The automatic difficulty adaptation using the heart rate as an indicator and biofeedback methods where the player is given feedback on his heart rate. This work compares, in the context of VR- exergames, these two methods regarding their differences in real and perceived effort, intrinsic motivation and immersion.
