Abstract

In this article, we discuss how to control nonverbal conversational signals (NCS) including eye gazes, noddings and facial expressions displayed by a pair of embodied agents for information presentation using their dialogues. Recent work on information agent proposes to present information to the users in the form of dialogues between a pair of embodied agents, aiming at clarifying the point that the users should be interested in. However, when agents have faces and bodies in order to be "embodied", the users read various meanings in the NCS displayed by the faces and the bodies of the agents, even if the agents are not actually designed to send NCS to their users but only to speak. Thus, we need to control the NCS of the embodied agents properly so that they convey appropriate meaning to the users. In order to cope with this problem, there is some work that discusses how to control NCS of an embodied agent. That work mainly focuses on the consistency of NCS with the speech utterances or the task assumed for the agent. However, when we employ dialogues between a pair of embodied agents for information presentation, we need to consider interdependences between NCS displayed by those two agents. In this article, we will propose a method for adjusting NCS displayed by a pair of embodied agents so that the interdependences between NCS are maintained. We will first explain the knowledge about the interdependences between NCS in human communication reported in the field of social psychology. Then, we will propose a procedure to maintain the interdependences between NCS of embodied agents in dialogues by satisfying constraints imposed on the NCS. Experimental results for evaluating the NCS realized by our procedure will also be given at the end of the article.
