We developed biological signal sensing system of a driver based on the vibration input through air pack sensor to detect drowsiness of the vehicle driver. To realize this system, a sensor seat capable of measuring pulse wave and detecting autonomous nerve activity change is developed. To show the effectiveness of the proposed system, we compared chronological average frequency pattern of pulse wave obtained from both finger plethysmogram and the air pack sensor pulse wave and investigated the possibility of sleep prediction detection and sleep point detection.
