In human-robot interaction, nonverbal robot cues such as gaze and emotional expression can potentially enhance coordination with nearby people via advantages like conveying a shared focus. At the same time, although laboratory studies have shown that expressive eye behavior increases the overall task performance while improving social perception of the robot, it is unclear whether these effects resoundingly generalize beyond the controlled laboratory environment into an unstructured public environment. We conducted an in-the-wild study to replicate the results of a previous in-lab study on expressive eye behavior (i.e., gaze and emotional expression) using a Hello Robot Stretch mobile manipulator. N = 55 participants interacted with the robot in a guided block placement task under one of four experiences: control, gaze only, emotion only, and both gaze and emotion combined. Participants in the gaze condition required significantly fewer attempts to select the correct block and reported the robot to be significantly more socially warm, suggesting that gaze may be a strong cue for directing collaboration as well as social perception in natural settings, while emotional expression could have more subtle impacts. These results can help robot practitioners create systems that fit more seamlessly and effectively into real-world settings.
