Abstract
With the growth of robot technology, more educational-support robots, which support learning, are paid attention to. However, there is a problem in these robots. The problem is that a user loses his/her interest in the robot. To solve this problem, some studies which focus on a model of emotional expressions have been reported in Human-Agent-Interaction. A model of emotional expressions is defined as the agent expressing his/her emotion as with autonomous emotions. These models were shown to be beneficial to effective interaction between an agent and a human. Thus, this paper examines how psychological effect of robot which expresses the emotion by using the model of emotional expressions can prompt learners in a collaborative learning.
