The objective of this paper is to propose a novel approach for the creation of user personas using common patterns in psychophysiological signals. We illustrate the persona creation process through a case example. Using this method, we were able to identify 4 distinct subgroups of varying experience and satisfaction levels. This novel approach illustrates the potential of physiological measures in the identification of various user clusters, based on one or more experiential aspect, as these signals can provide information as to what users are experiencing during the interaction without interference. This should be useful for user experience researchers, practitioners and designers alike to build more accurate user profiles, especially in the context of large scale public installations and immersive experiences.
