一种虚拟人追逐过程中的情绪博弈模型

A model of emotion game for chasing between virtual humans

追逐行为在人类社会生活中十分常见,模拟追逐过程中的情绪变化,有助于揭示情绪和运动的关系.在借鉴博弈论的基础上,研究了虚拟人围绕障碍物追逐的情绪博弈模型,依据追逐的剧情,拟定了虚拟人的情绪强度公式,定量描述了虚拟人的速度和体力的变化,提出了追逐过程中虚拟人情绪博弈策略.采用OpenSceneGraph图形库实现了虚拟人追逐动画,实验结果表明,该模型能很好地模拟追逐中虚拟人情绪的变化规律.

Chasing behavior is very common in human social life,and simulation of the emotion variation in a chasing process is helpful to reveal the relationship between emotion and motion.An emotion game model for chasing between virtual human around obstacles was studied on the basis of game theory.The formulas of the emotion intensities were constructed by a chasing story,and the variation of a virtual human＇s speed and energy were quantitatively described.The emotion game strategy for a chasing process was presented.The chasing behavior animation of a virtual human was realized in an OpenSceneGraph graphic library.The experimental results show that the model can closely simulate the variation of emotion in a chasing process.
