About
Yoshihiro Sejima is a researcher specializing in human-computer interaction, affective computing, and nonverbal communication systems, with a particular focus on the role of physiological and expressive cues in enhancing human-robot and human-avatar interaction. His most significant contribution is the pioneering development of pupil response systems — most notably the "Pupiloid" robot — which simulate human-like pupil dilation using hemispherical displays to convey emotion, foster empathy, and improve affective communication between humans and machines. Sejima's work demonstrates that subtle nonverbal signals, such as dilated pupils synchronized with speech patterns and laughter, meaningfully enhance users' emotional engagement and sense of affinity. Beyond pupil response technology, he has explored entrainment between speech and nodding behaviors, avatar-mediated remote communication, and interactive atmosphere visualization through complexion changes in avatar robots. His research integrates the InterRobot Technology (iRT) framework to generate naturalistic communicative actions driven by speech input. With his most-cited work accumulating up to nine citations, Sejima's research occupies a specialized but growing niche, offering valuable insights for researchers designing socially intelligent robots and emotionally responsive communication systems.
