Paper Published on Investigating the Effects of Gaze Behavior on the Perceived Delay of a Robot’s Response

Slow responses of social robots cause user frustration in human-robot communication.

Instead using verbal fillers like “urmm”, etc., can the robot use eye gaze—one of the important social cues in human-human interaction—to bridge the pause caused by a delayed response?

To answer this question, we—Vivienne Zhong, Prof. Dr. Theresa Schmiedel, and Prof. Dr. Rolf Dornberger—designed two conditions (with and without gaze behavior) and conducted a within-subject experiment involving 31 test subjects. We are pleased to present the recently published results of the experiment in the proceedings of the International Conference on Social Robotics 2019, available online at Springer.
