The authors have been studying the human response to a low-frequency oscillation using a ship-motion simulator and several passenger ships so as to establish an evaluating method of ride comfort on board vehicles. The purpose of this study is to evaluate human facial expression as a physiological index of his/her mental situation quantitatively. As a first step of the study, the present paper deals with quantification and characterisation of one's facial expressions by introducing the concept of Fourier Descriptor (FD). Analysis of face images of 17 subjects who have exhibited six fundamental emotions shows that the shape of a human eye can adequately be expressed with FDs and that the reconstructed shapes of eyes from average FDs agree well with characteristics that were investigated and widely known in the field of psychology.
