How do people make latent cognitive state explicit? We have focused on a joint attention which is a process to understand others' mind and proposed a self-feedback interaction that human establishes it with oneself. In this work, we designed Gaze Mirroring that an anthropomorphic agent actively establishes the joint attention with the user by imitating his/her gaze behavior in synchronization and sympathy. We confirmed that the user gazed longer at a visual object of interest in an experimental situation where the user made a choice from some objects. Through this work, we also yielded important findings to model relationships between human cognitive state, gaze behavior, and visual environmental context.
