如何为具有情感的虚拟代理创建有效的身体动画仍然是人类动画师的最新技术，也是计算机科学家面临的巨大挑战。在本文中，我们建议使用层次参数模型来表示身体动画：情感，风格，运动和程序参数。基于此模型，我们创建了具有通用动画程序的虚拟角色的运动，并将这些程序参数映射为文献中提出的样式参数。我们在之前的工作中通过实验验证了生成的动画的表现力。在本文中，我们进一步报告了两个实验的结果，试图验证风格参数如何映射到各种情绪中。结果表明，通过对中性动作（如步行）风格参数的操纵，被试可以成功地区分情绪。当这些风格参数用于情感动作时，包括敲打、颤抖、蓬勃发展和垂头丧气，生成的动画在预期的环境中更加有效。
How to create effective body animations for virtual agents with emotions remains the state of the art for human animators and a great challenge for computer scientists. In this paper, we propose to use a model of hierarchal parameters to represent body animations: emotional , style , motion, and procedural parameters. Based on this model, we have created motions for a virtual character with generic animation procedures and mapped these procedural parameters into style parameters as proposed in the literature. The expressiveness of the generated animations was verified through experiments in our previous work. In this paper, we further report the results of two experiments attempting to verify how the style parameters are mapped into various emotions. The results reveal that the participants can successfully distinguish emotions based on the manipulation of style parameters for neutral motions such as walking. When these style parameters were used for emotive motions, including pounding, shivering, flourishing and crestfallen, the generated animations were even more effective for intended contexts.
