Analysis of Timing and Effect of Visual Cue on Turn-Taking in Human-Robot Interaction

Abstract

This paper presents a communication robot system with a simple LED display for representing timing for turn-taking in human-robot interaction. Human-like conversation with non-verbal information, such as gestures, facial expressions, tone of voice, and eye contact enables more natural communication. If the robots could use such verbal and non-verbal communication skills, it would establish a social relation between a robot and human. Timing and time interval for turn-taking in human communication are important non-verbal cues to efficiently convey messages and to share opinions with each other. In this study, we present some experimental results to discuss the effect of response timing for turn-taking in communication between a person and a robot.
