In this paper, we investigate the change of biometric signal for sexual attractiveness. Eye camera system and electrocardiograph was used in our experiment to evaluate the change of pupil diameter and heart rate variability (HRV). Five young male students participated in our experiment that was attempted by the observation of the 10 female portraits belonging to the final selection of beauty contest. An interesting result that top two and bottom two entries appeared at the both ends was obtained by the measurement of HRV represented in Poincaré plot. This polarization in attractive patterns was implied by the emotional change of individual difference between the attractiveness for beauty or cuteness.
