NOTIFICATION CONTROL DEVICE, NOTIFICATION CONTROL METHOD, AND STORAGE MEDIUM

A notification control device performs: detecting a sightline of a driver; causing an information output device to output a first warning when a first condition is satisfied; and causing the information output device to output a second warning when a second condition is satisfied. The first condition is a condition that the driver's sight line is out of a predetermined range in which the driver is considered to see a view in front of the mobile object and a state in which the sightline is out of the range is maintained for a first time. The second condition is a condition that the driver's sightline is out of the range, a risky object to be noticed is present in a reference area, and the state in which the sightline is out of the range is maintained for a second time shorter than the first time.
