About
Raphaela Gehle is a leading researcher in human-robot interaction (HRI), specializing in the nuanced dynamics of robot-to-group communication in real-world settings. Her work focuses on how autonomous robots can successfully open, manage, and repair interactions with multiple human participants, particularly in challenging public environments like museums. Gehle’s major contributions include pioneering studies on the stepwise coordination of interaction openings—her most cited paper (51 citations) reveals how a museum guide robot can determine the appropriate moment to engage a visitor. She has also deeply explored “trouble signaling,” showing how groups multimodally indicate confusion when a robot’s next move is unexpected, and how robots can perform deictic “repair” actions to reorient visitors to exhibits. Her research on robot gaze as a tool for shaping visitor participation and managing multi-party engagement has been foundational, with cumulative citations exceeding 120. By combining qualitative case analysis with quantitative evaluation from real-world field trials, Gehle’s work provides critical insights for designing socially aware robots that can navigate the complexities of group interaction, making her a key figure in advancing autonomous, context-sensitive HRI.
