Development of Motion Visualization System Using Wearable Inertial and Bio-signal Sensors

Using motion capture is useful way to support exercises for rehabilitation or sports. However, typical systems are not able to be used in wide area because they are using a number of cameras to capture markers placed on the body. Therefore we propose a wearable inertial motion capture system that measure motion directly from various points on the body. Furthermore, the state of motion and its corresponding internal activity is visualized through simultaneous measuring of biosignals such as EMG. As a result we have confirmed it is possible to measure motion over a wide area as well as aid an intuitive understanding of movement through an integrated visualization of internal activity.
