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.
