Benefiting from the development of AR technology, AR museum games, a method of combining traditional museums with emerging information technology, can transform the knowledge display of museums from boring learning to active exploration, thereby improving the fun of the journey. By combining the museum auxiliary guide with AR games, the story of the museum exhibits is processed with interest, and the knowledge display of the serious museum becomes more vivid. The design is based on Unity 3d platform, and the Vuforia plug-in and UGUI interface controls that can be stable and efficient for image recognition are used to complete the development of museum AR games.展开更多

This paper presents an augmented reality tool designed to assist unskilled or amateur players of such games. The system is based on a projector and a Kinect 2 sensor placed above the table, acquiring and processing the game on-the-fly. By using depth information and detecting the table's rails(borders),the balls' positions, the cue direction, and the strike of the ball, computations predict the resulting balls' trajectories after the shot is played. These results—trajectories, visual effects, and menus—are visually output by the projector, making them visible on the snooker table. The system achieves a shot prediction accuracy of 98% when no bouncing occurs.展开更多
