Augmented practice mirror: A self-learning support system of physical motion with real-time comparison to teacher's model

Abstract

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. We propose Augmented Practice Mirror (APM) learning support system. APM shows the mirror image of learner's motion overlapped teacher's one, and the difference between them. These three images are shown simultaneously on a large screen as virtual mirror in real time. As a result of the experimental evaluations, it was found that APM was better in recognizing the difference between the participant's motion and the teacher's one than two common methods, and that the hybrid interface of voice recognition and gesture was better than the single interface of voice recognition or gesture for operating APM. © 2009 Springer Berlin Heidelberg.
