A study about psychophysiological measures in user experience monitoring and evaluation

Abstract

User experience (UX) has received increased attention in last years, in a reality of mobile applications and internet of things. In order to increase competitiveness, companies have been invested in understand user's emotions during the experience. However, this is still a challenge for HCI researchers. This article presents an investigation, as a part of a major research, based on 14 studies, about use of psychophysiological measures in HCI research. We found 1) that psychophysiological measures are still difficult to apply, once sensors are still invasive and difficult to understand and use; 2) each psychophysiological measure represents various emotions, and each emotion is measured by various psychophysiological measures; and 3) it is necessary to explore and discover more solutions to user's emotion measurement. This scenario shows an opportunity for UX evaluation methods, once a future work considers the use of psychophysiological measures.
