Research On Virtual Agent Perception Model

A goal of virtual environment is to build virtual world which has deep immersion sense, and make the users of the virtual environment (its users) seem to place himself in the real world. For ten years, Virtual reality technology is getting more and more ripe With researchers' constant effort .Now a lot of virtual environments can already reach the condition that can displace real environment on the visual effect.But these existing virtual environments are static and lifeless. Otherwise in the real world, a lot of targets are living .In order to imitate real world more lifelikly, the developers of the virtual environment need design one or more living targets in static virtual world, and construct the virtual ring of a intelligence Border.This text has discussed the questions of the following several respects around the virtual environment of intelligence.First it introduces some correlative conceptions and applications of virtual reality, Then discussing the development of the virtual environment of intelligence and research situation of virtual Agent.The Agent theory is one main methodology of the virtual environment of intelligence in aspects of imitating biological and imitating people structure at present. we introduce Agent theories and Agent system structure of artificial intelligence in the text,and lay an important basis for the research of virtual Agent of virtual environment, then make comparisons between the target's design program and Agent -oriented design program.After analyzing intrinsic shortcomings of .the virtual environmental model originally, we put forward one opinion that we create models of information layers of the virtual environment on the basis of original virtual environmental, it offers channels of information interchange and ways of knowledge intercourse to Virtual Agent in the virtual environment. .From the angles of modeling, we discuss geometry modeling, physics modeling, behavior modeling and cognitive modeling of virtual Agent, especially we emphasize the research of the behavior modeling method of the virtual environment. At last, The perception behavior as a kind of general behavior of the virtual reality has been studied; we also bring forward a model of perceiving for such general perception behavior.
