It has been demonstrated that virtual reality (VR) exposure can afect the subjective experience of diferent situations, cognitive capabilities or behavior. It is known that there is a link between a person’s physiological state and their psychologicalself-report and user experience. As an immersive experience can afect users’ physiological data, it is possible to adapt andenhance the content of a virtual environment in real-time base on physiological data feedback (biofeedback). With the rapidevolution of the physiological monitoring technologies, it is now possible to exploit diferent modalities of biofeedback, ina cheap and non-cumbersome manner, and study how they can afect user experience. While most of the studies involvingphysiological data use it as a measuring tool, we want to study its impact when direct and voluntary physiological controlbecomes a mean of interaction. To do so, we created a two-parts protocol. The frst part was designed to categorize theparticipants on their heart rate control competency. In the second part of the study, we immersed our participants in a VRexperience where they must control their heart rate to interact with the elements in the game. The results were analyzed basedon the competency distribution. We observed consistent results between our competency scale and the participants’ controlof the biofeedback game mechanic. We also found that our direct biofeedback mechanic is highly engaging. We observedthat it generated a strong feeling of agency, which is linked with users’ level of heart rate control. We highlighted the richness of biofeedback as a direct game mechanic, prompting interesting perspective for personalized immersive experiences.< Leer menos
