Abstract—The heuristic method presented in this paper is capable to calculate the translation of human body recording done with inertial motion capture (MoCap) costume. As an input the method takes only the movement described with the hierarchical kinematic model and acceleration data, however without translation of the root joint. We have compared the results obtained with our method with results generated by commercial software. As the test dataset we used eight MoCap recordings of karate katas performed by two black belt karate masters. Basing on our experiment the proposed heuristic method enables to produce valuable data that closely corresponds to direction of movements of a person wearing the costume. The method can be used for example to generate the correct visualization of various movements relatively to global reference frame.
