Abstract
Recently, more educational-support robots, which support learning, are paid attention to. However, the problem of these robots is that a user loses his/her interest in them. To solve this problem, some studies which focus on emotional expression models have been reported in Human-Agent-Interaction. The model of emotional expression is defined as the agent expressing its emotions autonomously. Although these models have been shown to be beneficial for effective interaction between an agent and a human, no reports have addressed the educational-support robots using these models. Thus, this paper studies how much learning effect with a robot which expresses the emotion by using the emotional expression model can be prompted for learners in a collaborative learning.
