摘　　要：为了在智能虚拟环境中赋予主体情感能力,提高其逼真度及人机交互的自然性,并且兼顾虚拟环境的实时性要求,以心理学中的基本情绪理论和认知评价理论为依据,模拟推理规则为基础,提出了一种情绪产生器模型。该模型首先根据模糊IF-THEN规则制定情绪激发条件规则,进而推理得出"情绪因子";然后建立了一个受情绪因子、个性及前一时刻的情绪状态制约的非线性函数,用来生成当前情绪及计算情绪强度。仿真结果表明,模型较符合人类的基本情绪状态的产生、迁移及衰减规律,在一定程度上体现了人类情绪的模糊性和非线性,而且易于机器实现。To equip the Agent with emotions,enhance its fidelity and natural interaction with human beings and to satisfy the real-time requirement in intelligent virtual environment,according to basic emotion theory and cognitive evaluation theory in psychology,an emotion model based on fuzzy rules was proposed.Firstly,＂emotion factor＂ was generated according to the emotion elicitation rules based on fuzzy IF-THEN rules.Then a nonlinear function restricted by personality,emotion factor and emotion state at the previous moment were used to compute emotion strength.The simulation result shows that this model can simulate the fuzzy and nonlinear characteristic of human emotion to a certain extent,and more importantly,it is easy to realize by computer program.
