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.
