A Motion Capture Quality Comparison Between Rokoko and Kinect

In human machine interaction tasks, the quality of motion capture plays a critical role. Rokoko Motion Capture System (Rokoko) is a relatively economic motion capture device and has been utilized in various areas of motion-related research. In this study, we test the representative ability of the products captured by Rokoko and Microsoft Kinect v2 (Kinect). Three non-professional actors wore the Rokoko to do three kinds of activities: walking with normal velocity, jumping with vertical acceleration and rotation, by displaying different body functions. Motion data were recorded using these two devices simultaneously. We compared the pros and cons of the results of the captured motions by these two devices and provide suggestions and precautions using Rokoko Smartsuit Pro for motion capture activities for researchers.
