Dynamics of brain functional signals during sustained attention to response task

Abstract

Driver distraction is recognized as a serious problem and is associated with a substantial proportion of traffic accidents. In this article, we report on the development and evaluation of a near infrared spectroscopy (NIRS) system for driver distraction detection. We observed an increase in the oxyhemoglobin signals measured on the forehead during sustained attention to response task (SART) error. In the case of SART error, reaction time tended to decrease. We confirmed the change of oxyhemoglobin signal and the change of reaction time accompanying the distraction. Based on these results, we propose that driver distraction could be evaluated using the developed NIRS device.
