This paper proposes a three-dimensional motion capture and feedback system of flying disc throwing action learners with use of Kinect device. Rather than conventional 3-D motion capture system, Kinect has advantages of cost merit, easy system development and operation. A novice learner of flying disc is trained to keep arm movement in steady height, to twist the waist, and to stretch the elbow according to the waist angle. The proposing system captures learners’ body movement, checks their skeleton positions in pre-motion / motion / post-motion in several ways, and displays feedback messages to refine their actions.

This paper proposes a three-dimensional motion capture and feedback system for flying disc learners with use of Kinect device. Compared with conventional 3-D motion capture systems, Kinect has advantages of cost merit, easy system development and operation. The proposing system captures learners' body movement, checks their skeleton positions in pre-motion / motion / post-motion in several aspects, and displays feedback messages to improve their motions. A novice learner of flying disc is trained to keep arm movement in steady height, to twist the waist, and to stretch the elbow according to the waist angle. A result of controlled experiment shows that the proposing system is effective for beginners to improve their movements. (C) 2013 The Authors. Published by Elsevier B.V.
