Support system for pocket billiards

A support system for beginners of pocket billiards has been developed. The system exhibits all the guiding lines, which mean the directions to shoot the cue ball in order to sink any of the balls into a pocket, and helps the player to know the easiest shot to sink a ball. The player is also able to know if he/she has shot the cue ball in the correct direction using the image in which the trajectories of the balls are superimposed on the guiding line. A GUI helps the player to easily use the system.
