Computer graphics for expressing robot-artificial emotions

The concept of active human interface (AHI) is proposed to accomplish a friendly communication between human and robot/computer, and this paper deals with 3D computer graphics technique to display the inner state of AHI, i.e., robot-artificial emotion by means of facial expression solid model of a human face is used as a media of displaying the robot artificial emotions and an action units (AUs) system is utilized to generate six basic facial expressions on 3D solid model of a human face. A neural network mapping between six basic facial expressions and AUs can succeed in displaying various mixed facial expressions on the human face model.<
