ケーススタディ:人との共同体験に基づくロボット日記による第三者視点での親密度向上効果の量的分析と意味分類

抄録

In this study, in order to examine the effect of shared experiences between humans and robots on the intimacy between the two, we examined changes in the robot's impressions by using a robot diary automatically generated from information during a joint experience. A robot diary was automatically generated by inputting the information obtained from the shared experience into a large-scale language model. To examine the effect of the proposed diary on the robot's impression, the robot and the researcher went for a walk and generated a diary including the interaction and dialogue history during the walk, and the experimental participants watched the walking video and evaluated the diary online. The results showed that the proposed diary made readers feel at ease significantly more in the robot's impression evaluation. In addition, when the impressions were examined for differences in diary content, the diaries with information during the shared experience were judged to be more favorable because they showed the robot's familiarity with the person from the robot. These results indicate that when a robot verbalizes and shares its own experiences with a person in a diary format, the intimacy between the two may be enhanced.
