About

Andreas H. Marpaung is a pioneering researcher in human-robot interaction (HRI) and affective computing, best known for developing the autonomous social robot "Cherry." His work bridges social informatics and cognitive modeling to create emotionally intelligent agents that engage meaningfully with humans. Marpaung's most influential paper, "A Social Informatics Approach to Human–Robot Interaction With a Service Social Robot" (2004, 63 citations), established foundational insights into how users perceive robot personality and emotion, revealing that people prefer service robots with affective capabilities. He further advanced the field by proposing an affective cognitive model based on Scherer’s emotion theory (2007), providing a computational framework for agents to simulate emotional responses. His three-layered architecture for socially intelligent agents (2005) models the multilevel process of emotions, from physiological to cognitive layers. Marpaung’s work on Cherry—a "little red robot with a mission and a personality"—demonstrated how autonomous systems can be designed for social roles, influencing subsequent HRI research. Though his citation counts reflect a niche but dedicated audience, his contributions remain critical for students and researchers exploring the intersection of robotics, emotion theory, and user-centered design.
