Controlling Robot's Gaze according to Participation Roles and Dominance in Multiparty Conversations

Abstract

A robot's gaze behaviors are indispensable in allowing the robot to participate in multiparty conversations. To build a robot that can convey appropriate attentional behavior in multiparty human- robot conversations, this study proposes robot head gaze models in terms of participation roles and dominance in a conversation. By implementing such models, we developed a robot that can determine appropriate gaze behaviors according to its conversational roles and dominance.
