Abstract-Nonverbal communication plays an important role in coordinating teammates' actions for collaborative activities. In this paper, we explore the impact of non-verbal social cues and behavior on task performance by a human-robot team. We report our results from an experiment where naïve human subjects guide a robot to perform a physical task using speech and gesture. Both self-report via questionnaire and behavioral analysis of video offer evidence to support our hypothesis that implicit non-verbal communication positively impacts humanrobot task performance with respect to understandability of the robot, efficiency of task performance, and robustness to errors that arise from miscommunication.
Prior work REF probed effects of nonverbal communication in human-robot teamwork and suggested that implicit nonverbal communication positively impacts human-robot task performance.
