Summary form only given. This lecture will introduce the world´s first method of detecting driver´s drowsiness level from the facial expression. The motivation is to realize the novel safety system which can detect the driver´s slight drowsiness and keep the driver awake while driving. The brain wave, especially alpha wave, is commonly used as the drowsiness index. However, it is not suitable for the in-vehicle system since it is measured with electrodes or sensors worn over the head. We precisely investigated the relationship between the change of brain wave and other drowsiness indexes that can be measured without any contact; drowsiness level evaluated from facial expression, low-frequency power content of eye-movement, fluctuation of heart rate, and distance of lane deviation from the center. This lecture will show you a process how we found the features of drowsiness from human and developed the method of drowsiness detection without any contact sensors.
