在本文中，我们强调了不同的挑战，在建模的沟通手势的会话代理（ECA）。我们描述的模型，其目的是捕捉和理解的具体特点的交际手势，以设想如何建立一个自动的交际手势生产机制。这项工作的灵感来自于对人类手势特征（例如，手的形状、运动、方向和相对于讲话的时间）传达意义。我们提出的方法来计算在哪里放置一个手势，手势的形状以及手势形状如何随着时间的推移而演变。我们专注于一个特定的模型的基础上的隐喻和体现认知的理论框架，认为人们可以表示，推理和传达抽象的概念，使用物理表示和过程，这可以通过物理手势传达。
In this paper we highlight the different challenges in modeling communicative gestures for Embodied Conversational Agents (ECAs). We describe models whose aim is to capture and understand the specific characteristics of communicative gestures in order to envision how an automatic communicative gesture production mechanism could be built. The work is inspired by research on how human gesture characteristics (e.g., shape of the hand, movement, orientation and timing with respect to the speech) convey meaning. We present approaches to computing where to place a gesture, which shape the gesture takes and how gesture shapes evolve through time. We focus on a particular model based on theoretical frameworks on metaphors and embodied cognition that argue that people can represent, reason about and convey abstract concepts using physical representations and processes, which can be conveyed through physical gestures.
