Abstract
Flexible Sensor Tube (FST) means a system that comprises multi-jointed series of angle sensors. It can calculate all joints' coordinates from all angles, and so it can measure the shape of it. In this paper, we focus on the FST's feature and each parts' shape of the human body. And we propose the calculation algorithm of the human body posture. The method uses the FST joints' coordinates in the FST worn around the arms and principal component analysis. In addition, we designed and manufactured the system "FST-Helix" packaging the method, and confirm the measuring capability of inspecting. On the other hand, we experiment and measure the method with FST-Helix. As a result, we can calculate arm length from system data and detect the posture with comparative high reliability by the statistical process.
