Role Of The Agent In The Virtual Environment Context-aware Model

Intelligent agent is the expression of the geometric and behavior characters of human in the space generated by computer (virtual environment).The ultimate aim for study Intelligent agent is to enable any use them in any virtual reality system that simulates the real world. The virtual reality technology that is closely related to humans have begun since the last century 80s.The virtual reality technology through real-world simulation provides a virtual platform. By the virtual platform, Human can be in a special and real ways to sensing and processing any work that is in the virtual world just like in the real world. It can be said that the virtual reality technology provides a new way for the human development, with the gradual development, the virtual reality technology has been widely used in many human applications. For example: medical simulation, games, entertainment, military simulation training, distance education, product testing and development.In this thesis, the main research aim is to design a perfect perspective model that can be used in any virtual world. Two ways are used in the design of the perspective model. One way is base on the sense of sight, another way is set up a field of force. Through the two ways, we have designed the vision sensors and the collision sensors, also achieve the function of the sensors. In the time of study, we get the common feature of virtual world through analysis of the virtual environment and the intelligent agent should be how to obtain the information of virtual world. With the analysis of perceived functional requirements, the object that in the virtual world has been divided in different types, while an environment information and knowledge model has been build. And base on the environment information and knowledge model, we design the object sensor and implement its functions.The purpose of this research is to make the intelligent agent has a high autonomy and intelligence, so that the intelligent Agent can obtain the information with its sensors. And then through its process mechanisms, the intelligent agent can analysis and process the information and transfer the final result to the act module that manifested through the behavior. Finally, The group animation verification system has been developed. The system can provide a platform that can test the environmental perception function of the intelligent agent.
