Influence of Users' Personality Traits on Impression of Robots' Reactions to Approach from Them

Abstract

Demands for interaction designs of therapy robots is projected to increase as the expansion of robot-assisted activity. In consideration of this situation, I compared the influence of users' personality traits on the impression of tolerant, rejective and emotional reaction robots to approach from users. As a result, I confirmed that extraversion and openness personality traits have significant influences on the extroversion and steady in the tolerant reaction robot, and the tolerance in the emotional reaction robot, respectively. I also confirmed that the rejective reaction robot creates significantly the narrow-minded than the others independently of users' personality traits. These results suggest that in designing interactions of therapy robots, it is better to design avoiding rejection reactions for any robot-assisted activity. In addition, it should be noted tolerant and negative reactions in designing interactions of therapy robots for robot-assisted activity expected to have many users who are high in extroversion and openness, respectively.
