Visualizing Velocity and Acceleration on Augmented Practice Mirror Self-Learning Support System of Physical Motion

An effective way to learn some physical motions such as dancing, playing sports, making traditional crafts, and so on, is to mimic teacher's motion. In this style of learning, it is important for the learner to recognize the difference between the teacher's motion and his/her one. Augmented Practice Mirror (APM) is a learning support system which shows the mirror image of learner's motion overlapped teacher's one, and the difference between them. In addition, the velocity and acceleration of the body movement is also important to understand the teacher's motion. In this paper, we propose a visualization method of the velocity and acceleration of the teacher's motion for the learner to understand it more easily and clearly.
