Does it make you shiver under your skin? Stating the importance of psychophysiological measures of well-being in player's experience

Aspects of eudaimonic well-being are already significant in Player Experience evaluation within Games User Research. To accurately assess how a player's well-being is influenced by their gaming experience, it is crucial to use not only self-report instruments, which rely on users' ability to recall and articulate their experiences, but also psychophysiological measures that can offer more reliable and nuanced data. Although further research is needed to clarify how physiological measures correspond to eudaimonic well-being in PX, this position paper argues that such understanding is essential to advance beyond superficial PX evaluation and explore how games resonate with players on a deeper level.
