Peitong Li investigates the intricate dynamics of gaze behavior in human interaction, focusing on how visual attention coordinates with action, gesture, and communication. Their most-cited work, "Gaze-action coupling, gaze-gesture coupling, and exogenous attraction of gaze in dyadic interactions" (2024, 9 citations), makes a foundational contribution by identifying three distinct functions of gaze during face-to-face encounters: acquiring information for one's own goal-directed actions, monitoring a partner's actions, and supporting multimodal communication through gaze-gesture coupling. Li critically highlights that current vision science models fail to capture this complexity, as they typically study gaze in isolation from social context. By systematically distinguishing between endogenous (volitional) and exogenous (stimulus-driven) gaze attraction within dyadic settings, Li's research bridges cognitive science, social psychology, and human-computer interaction. This work lays essential groundwork for developing more ecologically valid models of joint attention and interactive vision. With growing recognition in the field, Li's findings have immediate implications for designing responsive virtual agents, improving collaborative robotics, and understanding social attention disorders. Their research marks a significant step toward a unified framework of gaze in naturalistic social interactions.
