To make it behave as if an artifact (agent) has an internal model (model of others) is important as a design principle for making people understand the artifact (AI system) with increased autonomy. In particular, in this research, we focused on "time" and proposed a model that allows people to assume other models of artifacts by temporal overlapping of utterance behaviors in communication. In this paper, first of all, after overviewing our research on "duality of the body" and "temporal overlapping" in the interaction, we proposed a framework of "models of others emerging by temporal overlapping". We conducted experiments based on this framework and verified its validity. In the future, from this point of view, we are planning to conduct research on the interaction design of people and artifacts based on "time".
