In this article, we develop a system with a natural language interface to generate animation of small groups in environments with ambient crowds. Our system takes simple sentences of English as input and these sentences are parsed to obtain information about character attributes, behaviors, and locations for constructing situation nodes. These situation nodes form an animation graph for producing an animation of small groups. The interface assists in interactively managing and editing the animation graph. We demonstrate the effectiveness of the system in some examples. The user study results indicate that the proposed system is user‐friendly and flexible in producing animation of small groups in various scenes.

从自然语言界面生成具有丰富行为的小组

在本文中，我们开发了一个具有自然语言界面的系统，用于在有周围人群的环境中生成小组动画。我们的系统以简单的英语句子作为输入，对这些句子进行解析以获得有关字符属性、行为和位置的信息，用于构建情境节点。这些情境节点形成一个动画图，用于制作小组动画。该界面有助于以交互方式管理和编辑动画图形。我们在一些例子中证明了系统的有效性。用户研究结果表明，所提出的系统在制作各种场景中的小组动画时具有用户友好性和灵活性。
