Research On Application Of Interactive Intelligent Virtual Avatar Behavior Model

In the field of intelligent virtual environment, more and more engineering applications need to add intelligent virtual avatar, which typically performing human substitute in the virtual environments application system, because human activity can not do without the participation of human beings themselves at last. To some extent, users enter into the virtual world by intelligent virtual avatar, which is an unlimited expansion of human activities in time and space. Today, human has entered information technology age; one of the important features of this age is that the essential character of all kinds of things, all of events will be converted to digital information. Research on intelligent virtual avatar, simply understood as the digital problems of human beings themselves, strictly speaking, intelligent virtual avatar is based on virtual reality and artificial intelligence technology,it mainly studies all sorts of human characters(geometric, physical, perceptual, cognitive, emotional, mental, memory, behavior and social, etc.) is described to digitization in a computer-generated space(application virtual environment),is a highly realistic digital representation of human characteristics.Ideally, the intelligent virtual avatar should have a realistic real-world geometry appearance, in addition,it is more important to have the self-cognitive ability and emotional intelligence, it could provide a simple human-computer interaction for users to create user-friendly experiences and achieve integration between self-awareness and user-wishes,accordingly it could realize the real and convincible personify activities,raise the user's resonance,maximize enhanced the user's immersion.The research in this paper is based on the project'New Digital Funeral and Sacrifice System' which aims to solve the problems that encountered in China's Funeral Reform and provide an important direction for the second Funeral Reform,the most impertant topic is that how to build the online intelligent virtual environment. Face to the intelligent virtual environment,this paper designed a intelligent virtual avatar which is easy to implement and with expansibility, mainly research the behavioral model and human-computer interaction of the intelligent virtual avatar, and this paper give in-depth studies on the architecture of intelligent virtual environments, intelligent virtual incarnation of the autonomous cognitive behavioral model, synthetic emotion, behavior planning and control, and integration between self-awareness and user-wishes.Finally,it proposes method to realized these models,details include:(1)According to virtual reality online sacrificial system requirements, designed the overall framework of intelligent virtual environment, and the established a hierarchical model of information, knowledge.(2)Explored the relationship among the emotions, motivations and behavior, give the framework of intelligent virtual avatar of agent-based. Design the intelligent autonomous virtual incarnation of cognitive behavioral model.(3)According to system requirements, interactive intelligent virtual avatar behavior model is proposed, which the wishes of user and autonomy of avatar are syncretized.(4)Developed a prototype system of interactive intelligent virtual avatar based on Virtools 3D interactive engine.by running the prototype system and analyzing the behavior of intelligent virtual avatar,we get that the proposed model and related method is validated, the results fully demonstrated the validity of the model and methods.
