Abstract
Human Computer Interaction based Research has emerged in the early 1980s with the advent of computer technology. Human Motion Capture is the process of recording the movement of people. Among many kinds of human motion capture devises, Microsoft Kinect sensor and inertial sensors are most popular nowadays. In this paper we propose an efficient motion tracking mechanism to construct real time human skeleton animation using inertial sensors. We compare the results of our proposed method with the Microsoft Kinect sensor over the complicated motion tracking and joint position. During the experiment we observed that our results are much steady than Microsoft Kinect results. Some motions like hand cross over or leg cross over, our method showed better results than Kinect because the Kinect may lose skeleton of the blocked parts. On the other hand, since we use radio frequency inertial sensors, our method has a larger working area than Kinect.

IntroductionReal-time inertial tracking of human motion requires attaching inertial sensors to the major segments of human body
We performed the following experiments to evaluate the efficacy of our inertial sensor based human motion tracking system
The performance of system was fast and stably in an area of 20m×20m which is much larger than Kinect
Summary
Real-time inertial tracking of human motion requires attaching inertial sensors to the major segments of human body. Slyper and Hodgins created a performance animation system that leverages the power of low-cost accelerometers [4]. Even though their setup based on upper body suit, another study contributed their research by introducing a novel framework for generating full-body animations controlled by only four 3D accelerometers that are attached to the extremities of a human actor [5]. We introduce a wearable real-time human motion capture system using inertial sensors.
