Abstract: An anti-collision system configured for use in a ballpark is provided. The anti-collision system includes a first device that is configured for short range wireless communication and that is configured to be worn by a ballplayer, and a second device that is configured for short range wireless communication with the first device and being located on at least one of a wall of the ballpark, a dugout of the ballpark, and another ballplayer. When a distance between the first device and the second device is less than or equal to a predetermined distance, the first device is configured to provide an alert to the ballplayer, thereby preventing a collision between the ballplayer and one of the wall of the ballpark, the dugout of the ballpark, and the another ballplayer.
