About

Yaofeng Liu is a pioneering researcher in the field of affective robotics and human-robot interaction, with a focus on endowing machines with emotional intelligence. His work centers on developing humanoid robots capable of perceiving, expressing, and responding to human emotions through integrated speech, vision, and facial expression systems. Liu’s foundational research established an emotion model based on bionics, where a robot’s cognitive and reasoning processes drive its emotional expressions, enabling more natural and empathetic interactions. In his most cited work (2008, 7 citations), he created a humanoid robot that combines speech recognition, synthesis, face detection, and facial expressions, underpinned by a sophisticated affective model treating emotion transitions as a Markov process. He further advanced the field by applying Dempster-Shafer evidence theory to fuse emotional cues from visual and auditory inputs, and by integrating Maslow’s hierarchy of needs into robotic emotional systems. Though his citation counts are modest, Liu’s contributions are notable for their early, interdisciplinary approach to artificial psychology, laying groundwork for service robots that interact with humans on an emotional level.
