Abstract

The purpose of this study was to investigate the possibility for evaluating vigilance levels using a parameter of saccadic eye movement. EEG was measured and analyzed by means of fast Fourier transform, and the spectral power of α and β wave bands were obtained so as to extract [β]/[α+β] which was assumed to reflect vigilance levels. Eye movement was measured so as to calculate saccadic peak velocity (SPV) and relative SPV (RSPV) which was normalized by the mean SPV at the corresponding amplitude of saccade. The relationship between [β]/[α+β] and RSPV was investigated and it revealed that RSPV decreased according to the decline in the vigilance level. This indicates the possibility for evaluating vigilance levels using RSPV
