Research on Alert degree based on ERP

摘要

In daily life, lots of work need people maintain higher attention or vigilance. In the early study of vigilance, blink frequency, the impedance of skin, body temperature and blood pressure and other physiological signals was used to estimate the vigilance. EEG signal can more directly reflect the brain's activity than other physiological signals, and EEG signal have a higher time resolution. In this paper, ERP component was used to analyze the alert state, according to this study, the use of ERP component analysis can reflect the subjects' alertness.
