An AR Visualization System of Near-Future Information to Avoid Dangerous Situations

In recent years, there has been an urgent need to improve safety and efficiency to avoid dangerous situations. In this paper, the authors proposes a visualization system of near-future information by augmented reality (AR) to avoid dangerous situations. The proposed system utilizes the position and speed information of the user and obstacles, predicts crashes, and recommends avoidance actions such as changing course or stopping. Experiments were conducted under different conditions by the implemented system to determine how many seconds into the future it would be safer for the user and easier to take avoidance action. The experiment results showed that the avoidance rate was almost the same for 2 seconds or longer, but the best rate was for 3 seconds ahead.
