About
Takamasa Hattori’s research lies at the critical intersection of human-robot interaction and safety engineering, focusing on how people instinctively avoid harm when a robot’s sharp end-effector suddenly approaches their eyes. Through a series of psychological experiments, Hattori systematically documented human avoidance motions—such as blinking, head retraction, and turning—to quantify the “avoidability” of eye injuries in close-contact robotic systems. His 2012 study on avoidance action characteristics (10 citations) established foundational metrics for estimating injury severity, while his extrapolation simulation work (6 citations) modeled how observed reactions could predict real-world outcomes in coexistence environments. By integrating biomechanical data with psychological response patterns, Hattori’s research provides essential design parameters for safer robotic end-effectors and workspace layouts. His findings reveal significant individual differences in reaction speed and motion type, underscoring the need for personalized safety thresholds. Though his citation counts remain modest, Hattori’s work is pioneering in its focus on ocular injury prevention—a niche but vital area as robots increasingly operate in shared human spaces. His experiments offer a rare empirical bridge between human reflexive behavior and robotic risk assessment, informing standards for collaborative robot safety.
