We develop and present a portable tool intended for real time estimation of the center of mass (CoM) in human subjects. Using the statically equivalent serial chain (SESC) method we can account for subject specificity after identification of the model’s parameters. CoM position estimates are then available from measurements of the subject's limbs orientations. For portability, we make use of widely accessible sensors such as the Kinect and Wii balance board for identification. Use of the Kinect as a measurement device allows us to establish the SESC outside of the laboratory, without many special considerations on the environment. Only Kinect is used for CoM tracking after identification was performed. We present here an overview of the SESC concept and the identification procedure. The aspects involved in the visualization tool are discussed and results are shown in order to verify the performance.
我们开发并展示了一种用于实时估计人体重心（CoM）的便携式工具。使用静态等效串联链（SESC）方法，我们可以在识别模型参数后考虑个体特异性。然后，通过测量受试者肢体的方向即可获得重心位置估计值。为了便于携带，我们使用了如Kinect和Wii平衡板等广泛可用的传感器进行识别。将Kinect用作测量设备使我们能够在实验室外建立SESC，而无需对环境进行过多特殊考虑。识别完成后，仅使用Kinect进行重心跟踪。我们在此概述了SESC概念和识别过程。讨论了可视化工具所涉及的方面，并展示了结果以验证性能。
