Affect Misattribution Procedure: An implicit technique to measure user experience in HRI

This paper suggests new methodology for measuring User Experience in HRI. We suggest using implicit attitude to predict User Experience (Affect). Therefore we show a first validation study. The study uses short videos of a robot (IURO - Interactive Urban Robot) approaching a person and asking for the. IURO either approached a walking or a standing person. We measured people´s implicit attitude towards the robot with the Affect Misattribution Procedure (AMP). The results show that a walking person being approached by the robot evolves an implicitly more negative attitude in the observing participant whereas corresponding questionnaire items showed no difference in attitude for the approach behaviour. We conclude from these results that measuring implicit attitude in HRI is valuable for the evaluation of the User Experience of a robot.
