Abstract
The purpose of this study is development of the motion analysis system that contributes intuitive recognition of human motion and muscle activity. This system obtains electromyograms and motion data by optical motion capture system. Electromyograms are measured synchronously with motion data. This system generates avatar animation using three dimensional computer graphics (3DCG). The human motion data is assigned to the movement of the bone of the 3DCG model. The muscle activities are represented by color of avatar muscles. The characteristic of this motion analysis system is to contribute intuitive and instantaneous recognition of whole body motion and muscle activity by generating avatar animation at various view points. This system is adequate to estimate time variance of physiological conditions. This paper describes the outline of the proposal system, visualizing method for representing human motion and muscle activity using avatar animation, evaluating results applying this system to the visualizing of physical load during operation of center panel mounted on car console, and the characteristics of this system.
