使用动力系统和系统识别的工具，我们开发了一个框架，用于研究人体运动的原语，我们称之为movemes。我们的目标是通过将人体运动分解为一系列属于已知动力系统字母表的基本构建块来理解人体运动。我们开发了一个分割和分类算法，以减少一个复杂的活动到序列的movemes产生it.We测试我们的想法从五个人类受试者谁是使用计算机鼠标绘制图形的数据采样。我们的实验表明，我们能够区分动素，并认识到他们，即使他们发生在活动中包含一个未指定数量的动素。(C)2003爱思唯尔有限公司。保留所有权利。
Using tools from dynamical systems and systems identification, we develop a framework for the study of primitives for human motion, which we refer to as movemes. The objective is understanding human motion by decomposing it into a sequence of elementary building blocks that belong to a known alphabet of dynamical systems. We develop a segmentation and classification algorithm in order to reduce a complex activity into the sequence of movemes that have generated it. We test our ideas on data sampled from five human subjects who were drawing figures using a computer mouse. Our experiments show that we are able to distinguish between movemes and recognize them even when they take place in activities containing an unspecified number of movemes. (C) 2003 Elsevier Ltd.
