We develop an interface that bridges crowd simulation and natural language processing techniques so that casual users can produce crowd animation by text input. The interface adopts a parser and a tagger to analyze simple English sentences to convert them into intermediate data structures that encapsulate the essential elements of crowds. There are five stages: preprocessing, parsing input sentences, crowd generation, animation adjustment, and crowd animation. Our system supports basic behaviors including standing, walking, running, escaping, being attracted, and queuing. We conducted a user experience study to evaluate the interface. The results show that the interface is user‐friendly for casual users to produce crowd animation.

用于人群动画的休闲用户的自然语言界面

我们开发了一个界面，将人群模拟和自然语言处理技术连接起来，以便临时用户可以通过文本输入制作人群动画。该界面采用解析器和标注器对简单的英语句子进行分析，将其转换为封装人群基本要素的中间数据结构。有五个阶段：预处理、解析输入语句、人群生成、动画调整和人群动画。我们的系统支持基本行为，包括站立、行走、跑步、逃跑、被吸引和排队。我们进行了用户体验研究来评估界面。结果表明，该界面对于休闲用户制作人群动画是用户友好的。
