ユーザの性格特性がユーザの働きかけに対するロボットの反応による心理的ストレス緩和効果に与える影響

抄録

Considering that robot-assisted activities spread to ordinary homes, this study was conducted as a part of acquiring the information on the relationship between users' characteristics, reactions from a robot, and the effects of those reactions. I compared the influence of users' personality traits on psychological stress relief effects obtained by interacting with tolerant, rejective, and emotional reaction robots to approach from users. As a result, I confirmed that agreeableness and neuroticism personality traits have significant influences on relaxing the fatigue obtained by tolerant reactions from a robot and disarming the anger obtained by emotional reactions from a robot, respectively. I also confirmed that improving the vigor obtained by rejective reactions from a robot could not be expected independently of users' personality traits. These results suggest that it should avoid using the robot with a high ratio of rejective reactions in any robot-assisted activities. Besides, it is better to use the robot with a high ratio of tolerant reactions if a user with high agreeableness needs effects of relaxing the fatigue, and use the robot with a high ratio of emotional reactions if a user with high neuroticism needs effects of disarming the anger.
