Billiards is a fun and popular sport, but both route planning and cueing prevent beginners from becoming skillful. A beginner in billiards requires constant concentration and training to reach the right level, but without the right motivating factor, it is easy to lose interests. This study aims to induce interest in billiards and accelerate learning by utilizing billiard path prediction and visualization on a highly immersive augmented reality platform that combines a stereo camera and a VR headset. For implementation, the placement of billiard balls is recognized through the OpenCV image processing program, and physics simulation, path search, and visualization are performed in Unity Engine. As a result, accurate path prediction can be achieved. This made it possible for beginners to reduce the psychological burden of planning the path, focus only on accurate cueing, and gradually increase their billiard proficiency by getting used to the path suggested by the algorithm for a long time. We confirm that the proposed AR billiards is remarkably effective as a learning assistant tool.

As COVID-19 made it difficult to travel abroad and attract domestic tourists to foreigners, the phenomenon of MZ generations flocking to Jeju through consumption patterns occurred. In this study, if Jeju Island uses Jeju's rural tourism and smart glasses to study how to attract and cope with domestic tourists after the pandemic and build a mobile application or smart glass to tour based on village maps, the docent guide service through smart glasses will help tourists. Furthermore, it would be very beneficial to introduce a location-based service to provide the necessary information at the location according to the movement path of tourists. In fact, we conclude that it can be implemented through the development of the Hansung Baekje Museum, and hope that the actual media can be applied to free tourist courses such as Jeju Olle Trail, as it provides various contents in selective development such as AR and VR.
