Technical Skill Evaluation and Training Using Motion Curved Surface in Considered Velocity and Acceleration

Sports skill differences between beginners and experts are visualized and quantified by curvature and area of motion curved surfaces using Microsoft Kinect. However, the technical skills of the engineer are not clarified. The technical skills need expert motion trajectory, rhythm, and well-timing. In this paper, we visualize and quantify technical skills, such as engineering and job training. In addition, we suggest the velocity curved surface and acceleration curved surface in motion curved surfaces, and the beginner exercises the skill training using the motion curved surfaces. In this result, the beginner skill improves using the motion curved surface training.
