In this paper we are concerned with how we take one of possible perspectives to observe our talk-in-interaction. Most studies of conversational analysis take microscopic view to conversational transcription data as a trace of the interactions. With the perspective, little is known about conversational dynamics that we feel a responsibility to respond to others when we are greeted. The attempt to build sociable robots provides us with a novel perspective on social interaction. In studies of interactional organizations with social robots, we focus on a kind of action-perception cycle that we call “entrusting behavior” and “grounding” from the internal perspective of the robot. Our researches stress the way in which robots in the social field could, in a sense, be conscious of the indeterminacy of their actions' meanings. In the paper, several trials relating to how observe the interaction dynamics from internal view of social robots are discussed.
