The authors pointed out in the previous paper that it may be possible to understand / evaluate the psychological situation under stressed conditions analyzing facial expressions and feelings of subjects exposed to low-frequency oscillations. The present paper deals with the objective measurements, analyses and evaluation of emotional and psychological situation from analyses of facial expressions deliberately expressed by subjects. They added blinks for taking the dynamic changes of facial expressions into account. The method of discriminant analysis was applied to extract dominant parameters, and then the linear multiple regression analysis was applied to evaluate and estimate the relations between psychological situations and facial expressions. Though the number of experiments is not many, they obtained results that psychological situation may be estimated from facial expressions with relatively high possibilities.
