The robot´s eye expression for imitating human facial expression

Recently, robots have become important to facilitate in our life, for example, the home automation robot that can service humans for their activity routine at home. In this way, the interaction between a human and the robot also becomes the importance and helps the communication with each other that should be appropriate. Our proposed of this study is to develop the robot that can interact with the human based on human facial expression. As we known, the facial expression of the human is the most significant role for natural communication of emotions. Thus, we have attempted to develop the robot face, which could express the human-like emotion and could interact dynamically with the human. In this paper, we have developed the head robot interaction system formed on robot eye expression which could imitate the human emotion. Naturally, the human eye expression is more complex to perceive the specific emotion. For this reason, we have attempted to study and propose this paper as the new type of the robot emotional expression. This proposed is composed of the facial expression recognition (FER) system and the robot´s eye expression (REE) system. The FER can recognize the basic emotion of the human, consequently convey the emotional expression command to the REE system for eyes expression of the robot. This paper presents the processes of the system, and the experiment of FER and REE system. We have found that there have been some complex of the REE among the similar emotional expressions.
