Behavior Modeling and Scenario Authoring for Virtual Environments

本研究的目的是开发一种行为建模的计算框架，以适应在大规模虚拟环境中创建复杂场景的问题。该项目将开发一个基于分层并发状态机的建模系统，该系统支持对反应行为的控制，并提供协调行为以创建关键情况和事件的机制。第二个研究重点是创建创作工具，以促进虚拟环境的设计和计算机生成的代理发挥核心作用的场景的定义。这项技术在交互式实时模拟环境中有应用，例如用于驾驶员培训的车辆模拟、虚拟样机和驾驶安全的实验研究，这些环境要求在不过度限制受试者行动的情况下在试验中再现动态情况和环境，同时保持主体行为的多样性、响应性和自发性。

This objective of this research is to develop a computational framework for behavior modeling adapted to the problem of creating complex scenarios in large-scale virtual environments. The project will develop a modeling system based on hierarchical, concurrent state machines that supports the control of reactive behaviors and provides mechanisms for coordinating behaviors to create critical situations and events. A second research thrust is to create authoring tools to facilitate the design of virtual environments and the definition of scenarios in which computer generated agents play central roles. This technology has application in interactive, real-time simulation environments such as vehicle simulation for driver training, virtual prototyping, and experimental studies of driving safety that require dynamic situations and circumstances to be reproduced across trials without overly restricting subject's actions and while maintaining diversity, responsiveness, and spontaneity in agent behaviors.
