Primitives for Human Motion: A Dynamical Approach

Using tools from dynamical systems theory and systems identification theory we develop the study of primitives for human motion which we refer to as movemes. We introduce basic definitions of dynamical independence of LTI systems and segmentability of signals and, for two dimensional motions, we develop classification and segmentation algorithms. We test our ideas on data sampled from four human subjects who were engaged in a simple real-life activity including two movemes. Our experiments show that we are able to distinguish between the two movemes and recognise them even when they take place in an activity containing more than one moveme.
