AbstractMulti-node sensors for human posture detection, by acquiring kinematic parameters of the human body, helps to further study the laws of human motion. It can be used as reference for the quantitative analysis tool for some specific application, such as healthcare, sports training and military affairs, etc. Compared with the traditional optical method, posture detection based on the inertial sensors has smaller limitation of space, lower cost, and easier implementation. In this paper, a human posture detection system was introduced. Utilizing the parameter data obtained by the inertial sensors, three-dimensional angles of the human hand movement could be calculated via quaternion algorithm for data fusion. The angles data transmission among the sensor nodes was successfully realized by the human body communication(HBC) transceivers based on capacitive coupling of multi-carriers OOK modulation at the data rate of 57.6kbps. The bit error rate(BER) was less than 10-5. The human posture could be reconstructed on the PC host. Ultimately, the implementation of the overall result showed the feasibility of the system.
