An Imperfectly Perfect Robot: Discovering Interaction Design Strategy for Learning Companion.

Human-likeness plays one of the most important roles in the long-term relationship between a robot and human. However, most of the existing studies have not designed human-like imperfection that is frequently observed by humans towards robots or agents. In our research, through questionnaires and interviews, we confirmed that when designing a robot or agent that plays a learning companion role, the imperfect elements of the robot or agent act positively on the long-term relationship with the user, and we will verify this with future experiments.
