Computer-aided creation of visual impression on CG face

This paper deals with the selection of morphing elements of face organs such as forehead, eyebrows, eyes, nose, cheek, mouth, lips, jaw, and face contour that characterize the personality impression of our face, and then shows how to draw a typical face which can express human personality defined in the discipline of enneagram. We have found that 59 morphing elements, called here "impression units", are the most effective components and their combinations to display each face of 9 personality types defined in the enneagram. Finally, we have developed the computer program to create a facial expression of any of these human personalities on a CG face that may be used for an anthropomorphic computer agent.
