The Influence of Personality on Users' Emotional Reactions

In order to develop an accurate and robust neuroadaptive model based on users' idiosyncrasies, the interface needs to use personal information. In this article, we explore the extent to which automatic facial analysis can inform on users' idiosyncrasies. Facial emotion from 88 university students playing an emotionally charged video game was used to explore the relationship between personality trait and facial emotion in human-computer interaction context. We observed multiple statistically significant correlations between users' personality dimensions and their emotions. One personality dimension was mostly related to emotions: emotionality. This paper contributes to the HCI literature by underlining the importance of taking into account users' personality traits in analyzing their emotional reactions to interfaces. Neuroadaptive interfaces using emotional reactions would perform better by also controlling for personality traits of their users and enhance user experience.
