Examining Trust in Human-Robot Interaction

Abstract

Trust is an important topic in human-robot interaction (HRI), in scenarios ranging from human- robot collaborative teams to social companion robots. In this talk, I present an overview of the recent trust in HRI literature by describing a survey paper in which I categorize trust studies as being either performance-based or relation-based. I then go deeper into the concept of the latter type of trust by describing two HRI studies we ran that examined people’s relation-based trust in robots. The first looked at the interplay between trust, emotional intelligence, and gender expectations. The second looked at whether observing a robot touch a human on the shoulder affected trust in the robot. Running these studies led us to questions concerning the nature of measuring trust, specifically through questionnaires. I therefore then discuss our study in which we offered participants various HRI scenarios and had them rate their trust of the robots on commonly used trust measures; however, half of the participants had the option to rate each of the questions as being “Not applicable to this robot” or “Not applicable to robots in general.” Finally, I discuss plans for future work that will model trust tendencies based on characteristics of the participant.
