DRIVING ATTENTION AMOUNT DETERMINATION DEVICE, METHOD, AND COMPUTER PROGRAM

摘要

A driving attention amount determination apparatus includes: 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 attention amount 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.

1. A driving attention amount determination apparatus comprising:
an imaging section for imaging a vehicle front; a stimulation detection section for detecting a stimulation contained in a video captured by the imaging section and a time point of occurrence of the stimulation, and detecting whether a position of occurrence of the stimulation in the video is in a central visual region or a peripheral visual region of a driver; an electroencephalogram measurement section for measuring an electroencephalogram signal 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 a stimulation in the central visual region 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 a stimulation in the peripheral visual region as a starting point.
