About

Michael Koller is a researcher at the forefront of human-robot interaction (HRI), with a specialized focus on how robotic gaze shapes human behavior and attitudes. His work bridges the gap between human-human interaction (HHI) and HRI by systematically exploring how human-inspired gaze parameters—particularly gaze aversion—can be implemented in humanoid robots to improve user experience (UX). In his most-cited paper, "Robotic gaze and human views: A systematic exploration of robotic gaze aversion and its effects on human behaviors and attitudes" (2023, 8 citations), Koller provides a foundational framework for understanding how gaze dynamics influence conversational HRI settings. His earlier pilot study (2019, 2 citations) laid the groundwork for measuring the relationship between gaze aversion ratio (GAR) and interaction experience (IE), proposing experimental designs that have informed subsequent research. Though still early in his career, Koller’s contributions are notable for translating nuanced social cues from human communication into robotic behavior, offering practical insights for designing more natural and engaging social robots. His work is essential reading for students and researchers interested in the intersection of social robotics, nonverbal communication, and user-centered design.
