About

Yuichi Koyama’s research lies at the intersection of human-robot interaction, assistive technology, and video-mediated communication, with a particular focus on supporting elderly and disabled users. His major contribution is the development of a robot-assisted videophone system that actively listens and adjusts media controls to compensate for users’ unengaging or uncongenial attitudes during video calls. By coordinating the robot’s behaviors—such as nodding and gaze—with real-time media adjustments, Koyama’s system facilitates more comfortable and natural conversations for individuals who might otherwise struggle with traditional video communication. His work also includes methods for estimating users’ conversational states, such as whether they are concentrating or not, by combining user actions with feature normalization. Although his citation counts are modest (with top papers receiving 5 and 4 citations), his research addresses a critical and underserved need: enabling social connection for vulnerable populations through intelligent robotic mediation. Koyama’s innovative integration of robot behavior and video control represents a thoughtful step toward more inclusive communication technologies.
