基于动机模型的自主性虚拟人行为选择研究

RESEARCH ON MOTIVATION MODEL BASED BEHAVIOUR SELECTION OF AUTONOMOUS VIRTUAL HUMAN

自主性虚拟人的研究是人工生命和计算机动画交叉融合的新领域。但是由于人的心理活动是一个整体的过程,动机、感知等这些参数都是互有联系和影响的,目前的研究仍然只是局部和有限的。借鉴马斯洛理论,基于动机模型框架提出一种简化的抑制和疲劳模型控制的虚拟人自主行为选择机制,实验结果表明,该方法较好地解决了在资源有限的动态虚拟环境中,虚拟人如何在多个相互抑制的行为之间对行为进行仲裁和选择。经实验证明,该研究可以应用于智能交互领域。

Research on autonomous virtual human is a new field that integrates artificial life and computer animation together.But as a result,people＇s psychological activity is a whole process,all of these parameters are interdependent and mutually influential,such as motivation,perception and so on,and current research is still local and limited.In this paper,a selection mechanism for autonomous behaviour of virtual human controlled by a simplified inhibition and fatigue model is proposed based on motivation model and use for reference on Maslow Theory.Experiments show that our method well solves the problem that how the virtual human makes arbitration and selection on behaviour among mutually inhibited behaviours in dynamic virtual environment with limited resources.Experiments also prove that this study can be applied to intelligent interaction and other fields.
