Motion recognition and generation by combining reference-point-dependent probabilistic models. Sugiura, K. & Iwahashi, N. In Proceedings of the IEEE/RSJ International Conference on Intelligent Robots and Systems, pages 852-857, Sept, 2008.
doi  abstract   bibtex   
This paper presents a method to recognize and generate sequential motions for object manipulation such as placing one object on another or rotating it. Motions are learned using reference-point-dependent probabilistic models, which are then transformed to the same coordinate system and combined for motion recognition/generation. We conducted physical experiments in which a user demonstrated the manipulation of puppets and toys, and obtained a recognition accuracy of 63% for the sequential motions. Furthermore, the results of motion generation experiments performed with a robot arm are presented.
