Abstract:
1. A visual confirmation evaluating apparatus comprising: a head position acquiring unit configured to acquire head position data indicating a head position of a driver within a vehicle; a line-of-sight acquiring unit configured to acquire line-of-sight data of the driver; a velocity acquiring unit configured to acquire velocity data of the vehicle; a storage unit configured to store three-dimensional map data representing a map of a real world in which the vehicle travels by three-dimensional shape data, and definition data including an identifier to identify each of intersections, a viewing reference, a confirmation time and an elapsed time; wherein the definition data define the viewing reference in the three-dimensional map data for each of the intersections identified by the identifier, and the viewing reference is position information of a virtual target that is to be confirmed by the driver when the vehicle enters each of the intersections for each road on right and left directions of each of the intersections; wherein the confirmation time indicates a time required by the driver to make a visual confirmation that is to be made from a position where each of the intersections is visible, wherein the elapsed time indicates a maximum delay time of a timing at which the driver makes a decision to move the vehicle, a position and direction acquiring unit configured to acquire position data and direction data indicating a position and a direction of the vehicle in the three-dimensional map data; a viewing information generating unit configured to generate viewing direction information indicating a direction towards the viewing reference from the head position of the driver indicated by the head position data, and unobstructed state information indicating a state in which the viewing reference is visible from the driver, based on the head position data, the line-of-sight data, the vehicle position data, the direction data, the definition data and the three-dimensional map data; and a visual confirmation evaluating unit configured to evaluate an appropriateness of a visual confirmation operation of the driver, based on the head position data, the line-of-sight data, the vehicle position data, the direction data, the definition data, the unobstructed state information and the viewing direction information.
