Uncertainty control of head shaking for virtual human based on cloud model
Yanfeng Fan · Jisuanji yingyong yanjiu · 2011
Taking the example of expressing negative information with head shaking of virtual human,designed three cloud models,which were the maximal head shaking angle negative cloud,the head shaking times negative cloud,and the head shaking speed negative cloud.Their drops were generated by respective positive cloud generation algorithm,to obtain maximal head shaking angle,head shaking times,and head shaking speed.The three control parameters distribute normally around their respective expected value.Results of simulation experiment show that the proposed cloud-based head shaking algorithm can generate control curves of head shaking action serials with disciplinary differences.Feature values of the three kinds of cloud models are proposed.
