摘要

In this study, we construct a system that promotes arousal by sounding an alarm according to a score, which is based on the estimated electroencephalogram (EEG) and blink components of a waveform obtained from a single electrode attached to the scalp. In this system, the arousal score is defined by the first principal component after calculating the magnitude of frequency components of the EEG and blinks from the measured waveform. The score is used to evaluate the degree of arousal, and a warning sound is generated when the score falls below the set threshold. To evaluate the performance of this system, we used two indices to determine the accuracy of drowsiness detection: comparing the timing of the warning with a video inspection and the score obtained from a questionnaire given to the subjects after the experiment. As a result, although there were variations among individuals, for 10 subjects, the average video inspection-based accuracy was 79.5% and the average questionnaire result was 4 on a 5-point scale. In addition, the subject's alertness increased immediately after the warning and the arousal score increased, showing the effectiveness of this method.
