Abstract: A remote health monitoring system based on IMU was presented. Acceleration data,magnetic data and angular data were collected by the llVIU tied up on human body. The raw measurement data was then processed by Kalman filter algorithm to produce a quaternion representation of orientation. Finally the BVH file containing the data captured above was transmitted to a remote PC of the doctor. The results show that the system is able to capture the motion data accurately and reproduce the movement of the human in real time.
