Abstract

Provided is a human motion tracking system based on Zigbee / institute of electrical and electronic engineers (IEEE) 802.15.4. A wireless wearable sensing network is covered on nine independent limbs of a person, and a wireless wearable sensing node is adhered onto each independent limb for monitoring free motion of the limb in the three-dimensional space. In each wireless wearable sensing node, an inertia measuring unit which comprises a three-axis acceleration sensor, a three-axis gyroscope and a three-axis magnetic force sensor is used for calculating the position of the independent limb in the three-dimensional space through an on-line data infusion calculation method. In the wearable wireless sensing network, real-time location data can be transmitted to a substation through the low-consumption wireless communication technology Zigbee / IEEE 802.15.4. The substation forwards the obtained wireless wearable sensing network to a computer in real time. Human motion can be reconstructed in the computer according to a forward motion model. The reconstructed human motion can be transmitted to a remote user through the internet for tememedicine. The human motion tracking system totally eliminates ligature between sensor nodes, do not need a light source for assisting and facilitates system expansion and application development by means of the low-consumption wireless operation system.
