During conversations, speakers establish their and others' participant roles (who participates in the conversation and in what capacity)—or “footing” as termed by Goffman—using gaze cues. In this paper, we study how a robot can establish the participant roles of its conversational partners using these cues. We designed a set of gaze behaviors for Robovie to signal three kinds of participant roles:...
This paper reports a study about system response time (SRT) in communication robots that utilize human-like social features, such as anthropomorphic appearance and conversation in natural language. Our research purpose is to establish SRT design guidelines in communication robots. The first experiment observed user preferences toward different SRTs in interactions with a robot which indicated that...
