Sympathy expression model for the bystander robot in group communication

Abstract

In this paper, we propose a sympathy expression model for a bystander robot that honors the concept of moral emotion. Therefore, we pay attention to the robot that is in a bystander position, which is unrelated to the communication between participants. We propose a sympathy expression model that lets a bystander robot learn the emotional display of others and enables cooperative expressiveness. This model allows the appropriate expressiveness affecting communication of a robot in the position of a bystander. To test it, we assume the interaction of three robots with the emotion generation model using the neural network. Further, we inspect the movement of this model by using a psychology model. As a result, we confirmed the appropriate actions of this model.
