In response to the need for quantitative information in diagnosing psychiatric disorders, we have developed an automated interview, automated extraction of facial organs, and acquisition of quantitative diagnostic information. We tried to obtain quantitative data for diagnosis by analyzing facial expressions during automated interviews. We focus on the movement of the pupils and head and the correlation between them, i.e., we develop a method for automated measurement of time sequential movements for the position of the pupil in relation to the frontal view of the face. By calculating the correlation between them, we obtain quantitative information that enables us to diagnose, for example, whether a subject may be schizophrenically inclined.
