Creating autonomous, Perceptive and Intelligent Virtual Humans in a Real-Time Virtual Environment

Tsinghua Science and Technology 2011年第3期16卷 233-240页

Creating realistic virtual humans has been a challenging objective in computer science research for some time. This paper describes an integrated framework for modeling virtual humans with a high level of autonomy. The framework seeks to reproduce human-like believable behavior and movement in virtual humans in a virtual environment. The framework includes a visual and auditory information perception module, a decision network based behavior decision module, and a hierarchical autonomous motion control module. These cooperate to model realistic autonomous individual behavior for virtual humans in real-time interactive virtual environments. The framework was tested in a simulated virtual environment system to demonstrate the ability of the framework to create autonomous, perceptive and intelligent virtual humans in real-time virtual environments.

Human Centered Design in Multi-agent Virtual Environment

引用

Computer Aided Drafting,Design and Manufacturing 2007年第2期17卷 49-57页

作者： WANG Zhao-hui ZHENG Guo-lei ZHU Xin-xiong School of Mechanical Engineering ＆ Automation Beijing University of Aeronautics and Astronautics Beijing 100083 China

The efficient and reliable human centered design of products and processes is a major goal in manufacturing industries for numerous human factors must be taken into account during the entire life cycle of products. A multi-agents intelligent design system is presented for manufacturing process simulation and products＇ ergonomic analysis. In virtual design environment, the virtual human with high-level intelligence performs tasks＇ operation autonomously and shows optimum posture configuration with ergonomic assessment results in real time. The functions are realized by intelligent agents architecture based on a modem approach derived from fuzzy multi-objects decision-making theory. A case study is presented to demonstrate the feasibility of the suggested methodology.
