Evaluation of Driver's Cognitive Load Caused by Present Information using P3 Latency in Eye-fixation Related Potential

Abstract

Efforts towards using P3 component of EFRP(Eye-Fixation Related Potential) as an evaluator for information recognition process are presented here. Seven experimental subjects were required to execute a simulated driving task and five visual tasks which differ in the complexity of decision process. EFRP was calculated from EEGs which artifacts are eliminated by the ICA method and P3 components were able to be identified in five subjects. The P3 latency showed a correlation with response time and subjective strain caused by visual tasks. It suggests a possibility for using P3 latency of EFRP in the assessment of driver's cognitive load.
