The physical exercise has internal and visual problems for the teacher. The internal problems are subjective estimation and tacit knowledge, the visual problems are single viewpoint and occlusion. In this paper, we suggest and verify the effectiveness of the e-learning system for solving problems. It has 3D body motion capture from multiple view function and the movie image linked teaching comments recording database. 3D body motion capture for visual problems uses Microsoft Kinect, which has 3D skeleton model rendering and multiple viewer function using Kinect Studio. The teaching comment movie database for internal problem accumulates the wrong images, correcting comments, and objective estimations. After that, we experiment the physical exercise in swimming and karate motion using the e-learning system for investing its effectiveness. In this result, the teaching comments from multiple viewpoints and recorded database are found for solving internal and visual problems.
