a processor; and
a memory storing instructions that are executable by the processor and cause the processor to
acquire a degree of deviation of the vehicle from the lane,
determine whether the acquired degree of deviation is classified into one of two or more predetermined patterns based on a relative position between the vehicle and the lane, and
in response to the determination that the acquired degree of deviation is classified into one of the two or more predetermined patterns, send, to a wearable device worn by the driver of the vehicle, information for causing a vibration device contained in the wearable device to vibrate in a pattern according to the acquired degree of deviation;
wherein the two or more predetermined patterns include:
a first pattern where an outer edge of a tire of the vehicle is positioned inward from an inner edge of the lane in a width direction of the vehicle;
a second pattern where the outer edge of the tire is positioned inward from a midpoint between the inner edge and an outer edge of the lane in the width direction;
a third pattern where the outer edge of the tire is positioned outward from the midpoint of the lane in the width direction; and
