Abstract:
1. A driving attention amount determination apparatus comprising: an electroencephalogram measurement section for measuring an electroencephalogram signal of a driver; a central stimulation presentation section for presenting a visual stimulation in a central visual field of the driver; a peripheral stimulation presentation section for presenting a visual stimulation in a peripheral visual field of the driver; a threshold setting section for setting a determination threshold for attention amount determination from a distribution of amplitude of an event-related potential in the electroencephalogram signal based on a point of presenting the stimulation in the central visual field as a starting point; and an attention amount determination section for determining an amount of attention through a comparison between the determination threshold and an amplitude of an event-related potential in the electroencephalogram signal based on a point of presenting the stimulation in the peripheral visual field as a starting point.
