Shall I Be Like You? Investigating Robot’s Personalities and Occupational Roles for Personalised HRI

The aim of this work is to understand how individuals’ personality differences affect their interaction with robots considering the robots expressed personalities and their occupational roles. For this purpose, we analysed the link between the degree of extroversion/introversion of the user and the one expressed by the robot during two different tasks: a cognitive task (i.e., movie recommendation) and a service task (i.e., bartending). We observed that participants showed a greater preference for a robot with an extroverted attitude in both tasks. The degree of pleasantness of the robot was affected by the users’ personality. Moreover, participants preferred an extroverted robot for the occupational categories of Entertainer and Organizer, while they associated an introvert robot to Producer and Organizer roles.
