1. A control method of an electronic apparatus, comprising: determining whether a specific event occurs; calculating an average speed of a vehicle if the specific event occurs; when the average speed of the vehicle is slower than an event speed of the specific event, generating a first object and when the average speed of the vehicle is faster than the event speed of the specific event, generating a second object, wherein each of the first object and the second object indicates a relationship between the average speed and the event speed; mapping the first object and the second object onto a road region of an augmented reality image; and displaying at least one of the first object and the second object through the augmented reality image in accordance with a speed difference between the average speed of the vehicle and the event speed, wherein the first object and the second object have different size and location on the augmented reality image, wherein a mapping position of the first object on the road region fluidly changes according to the speed difference between the average speed of the vehicle and the event speed, wherein a mapping position of the second object on the road region does not fluidly change regardless of the speed difference between the average speed of the vehicle and the event speed, and the second object is displayed at a lower of the road region of the augmented reality image, and wherein the mapping position of the first object is located higher than the mapping position of the second object on the road region.
