Outline of Final Research Achievements

In this research, we developed the analytical method for psychogenetic fatigue by using three challengeable measurements such as Eye-tracking, Facial analysis, and Heart beat variability with camera. At the case of eye tracking, we can find the change of reaction time in the voluntary eye movement with judgment task in our brain. At the case of facial analysis, we developed the time-series estimation method of conscious condition. Moreover, we challenged a non-contact measurement of heart rate variability (HRV) by using the commercial-based camera. By adding the biometric-based idea to extract the hemoglobin signal from facial image, we can performed the reliable measurement of HRV with the non-contact method. As mentioned above, our research was accomplished the proposed plan, however, it is noted that our given stress for psychogenetic fatigue was a temporal brain load. Therefore, we should verify our methods in clinical case of psychogenic fatigue as a future work.
