About

Haruhiro Katayose is a pioneering researcher whose work bridges the worlds of artificial intelligence, human–robot interaction, and the arts. His key research areas include Kansei (affective) information processing, music informatics, and humanoid robotics. Katayose’s most influential contribution is the *Kansei Music System* (1989, 43 citations), an early and visionary project that applied pattern recognition to music transcription and emotional expression—laying groundwork for today’s affective computing and creative AI. He also led the development of the *Virtual Performer* (1996), a music-playing robot that demonstrated how machines could interpret and perform music expressively. In robotics, Katayose advanced natural locomotion with the *extended-knee walk* (2009), enabling humanoid robots to walk with humanlike leg extension using parallel-link mechanisms—a departure from the bent-knee gait common at the time. His work is notable for its interdisciplinary ambition, merging engineering with aesthetics and emotion. With decades of research at Osaka University, Katayose has shaped how machines understand, express, and move with human-like sensitivity.
