Quantitative evaluation of the kinect skeleton tracker for physical rehabilitation exercises

Using video game technology in physical rehabilitation has shown many positive results in the past few years. The release of the Microsoft Kinect has presented many new opportunities for development in physical rehabilitation technologies. However, there have been questions about the Kinect's accuracy in actual experimentation. In this paper, we compare skeleton data obtained by a Kinect to that obtained by a VICON system in order to determine the accuracy of the Kinect while a tracked subject is moving their arm around. This is the first steps towards a much larger physical rehabilitation system.
