Abstract

Studies have shown that drivers' emotions can be assessed via changes in their physiology and facial behaviour. This study examined this approach as a means of gauging user experience (UX) in an automotive user study. 36 drivers' responses to typical UX-style questions were compared with computational estimates of their emotional state, based on changes in their cardiac, respiratory, electrodermal and facial signals. The drivers' arousal and valence levels were monitored in real-Time as they drove a 23-mile route around Sunnyvale, CA. These estimates corresponded with two independent observers' judgments of the drivers' emotions. The results highlighted a disparity between the self-report and algorithmic scores-the drivers who answered the UX questions more positively experienced higher levels of stress-evidenced by higher arousal and lower valence algorithmic scores. The findings highlight the value of supplementing self-report measures with objective estimates of drivers' emotions in automotive UX research.
