1. A driving assistance apparatus, comprising:
a driver identifying unit that identifies a driver driving a vehicle;
an evaluation data obtaining unit that obtains, based on an identification result of the driver identifying unit, evaluation data on the driver's visual cognitive ability for an event that occurs when the driver is driving the vehicle;
an event detecting unit that detects whether or not the event has occurred, on the basis of surrounding information data indicating a situation of the vehicle's surroundings; and
a processing unit that
determines, in a case where the event has been detected and on the basis of the evaluation data on the driver, the evaluation data being related to the event, whether or not notification information is to be output from an output unit,
does not cause the output unit to output the notification information in a case where the driver's visual cognitive ability is evaluated high, and
causes the output unit to output the notification information in a case where the driver's visual cognitive ability is not evaluated high,
wherein the evaluation data on the driver's visual cognitive ability is evaluation data obtained based on at least one of arrival time and duration time when an evaluation image including an event occurred while the vehicle is traveling is displayed to the driver, the arrival time being a period from a time point of start of display of the evaluation image to a time point at which a point of regard of the driver reaches a determination area first, the determination area being an area related to an event included in the evaluation image, the duration time being a period over which the point of regard of the driver is in the determination area, the evaluation data evaluating whether the driver's visual cognitive ability is high or not by any of methods (a) to (c):
(a) when the arrival time is less than a first predetermined time or when the duration time is less than a second predetermined time, evaluating that the driver's visual cognitive ability is high, or otherwise, evaluating that the driver's visual cognitive ability is not high,
(b) when the arrival time is less than the first predetermined time and the duration time is less than the second predetermined time, evaluating that the driver's visual cognitive ability is high, or otherwise, evaluating that the driver's visual cognitive ability is not high, and
(c) when a total time of the arrival time and the duration time is less than a third predetermined time, evaluating that the driver's visual cognitive ability is high, or otherwise, evaluating that the driver's visual cognitive ability is not high.
