根据面部表情的微妙特征，微笑可能会传达不同的含义。在这篇文章中，我们研究了一个虚拟主体所表现出的有趣、礼貌和尴尬的微笑的形态和动态特征。开发了一个Web应用程序，用于收集用户直接构建的虚拟智能体的微笑描述语料库。基于语料库，使用决策树分类技术，我们提出了一种算法来确定虚拟主体可能表达的每种类型的微笑的特征。所提出的算法使人们能够生成与礼貌、尴尬和有趣的微笑相对应的各种面部表情。
A smile may communicate different meanings depending on subtle characteristics of the facial expression. In this article, we have studied the morphological and dynamic characteristics of amused, polite, and embarrassed smiles displayed by a virtual agent. A web application has been developed to collect virtual agent's smile descriptions corpus directly constructed by users. Based on the corpora and using a decision tree classification technique, we propose an algorithm to determine the characteristics of each type of the smile that a virtual agent may express. The proposed algorithm enables one to generate a variety of facial expressions corresponding to the polite, embarrassed, and amused smiles.
