Classification of Vigilance Based on EEG

Abstract

Vigilance (also known as continuous attention) is an important type of human attention, closely related to the cognitive activities of life and work. Many human-computer interaction systems require vigilance of the operators to be kept at a certain level in critical tasks. In view of the problem that the vigilance of operators decreases as the time and difficulty of performing tasks in crucial positions increase, it is necessary to monitor the vigilance. This paper summarizes the advantages and disadvantages of physiological signal evaluation vigilance, and proposes classifying vigilance based on EEG method. The results show that the vigilance can be well evaluated, remedial measures can hence be taken avoiding the loss caused by the decreased vigilance.
