摘要
在计算机动画领域,创建具有情绪表现力的虚拟人运动是一个有趣话题。在综述前人工作的基础上,提出了一种情绪驱动的虚拟人行走模型。引入情绪因子来描述虚拟人的情绪状态,建立了情绪因子、运动姿态和速度变化的定量关系,采用运动学的方法实现虚拟人的行走运动。通过仿真实验,发现随着情绪因子的增大,可以增加虚拟人的运动步幅,同时虚拟人的头部倾斜度也由低头变成仰头,结果验证了引入情绪因子可以有效增强虚拟人的情绪表现力。
Creating a virtual human with emotional movement is an interesting topic in the field of computer animation. An emotion based walking model was proposed based on previous research on virtual human. Emotion factor was introduced to describe the emotion state of a virtual human, the quantitative relationship among emotion factor, walking posture and walking speed was set up, the walking process was realized in kinematics based method. In the simulation experiment for a virtual skeleton, when the emotion factor becomes bigger, the walking stride will increase, and the virtual skeleton will turn from lowering head to raising head. The result shows that emotion factor can effectively enhance the emotion expressiveness.
