About

Naoya Koizumi is a pioneering researcher in human-computer interaction, specializing in robotic user interfaces (RUIs) and pseudo-haptic feedback systems. His work bridges the gap between physical and digital interaction, with a focus on creating intuitive, embodied interfaces. Koizumi’s most notable contribution is the development of a teddy-bear-based robotic user interface, first introduced in 2005 and refined in 2006, which reimagines robots as agents for interpersonal communication and physical interaction. This concept, accumulating over 20 citations, has influenced the design of tangible, emotionally engaging interfaces for entertainment and communication. More recently, Koizumi advanced the field with Charrot (2018), a novel pseudo-haptic approach that combines mid-air imaging with vibrotactile cues to enable interaction with computer-generated characters. This work, though newer, demonstrates his commitment to merging visual and tactile feedback for immersive experiences. Koizumi’s research has been presented at top venues like ACM SIGGRAPH and IEEE conferences, and his teddy-bear RUI remains a landmark in robotic interface design, inspiring subsequent work in haptics and social robotics. His contributions continue to shape how humans interact with digital and robotic systems.
