Development of stance correction system for billiard beginner player

The billiard is necessary to acquire proper stance. If the player hit the ball in irregular stance, he or she would occur that mishits or the ball does not roll to the aimed place. Learning and using proper stance is the most critical aspect of a person's early billiard career. Thereby, we have been developing stance correction system. When the rear elbow is a right angle or the forward arm stretches, that stance is correct. Therefore, this system captures the player using the Kinect, and compares the angle of rear elbow and forward shoulder with thresholds. Using this system, the beginner can enjoy if he or she participates in the game.
