基于云模型的人—虚拟角色思想交互模型

基于情感、动机的非语言交互是影响人—虚拟角色交互效果的重要因素,提出了基于云模型的人—虚拟角色非语言交互模型。以尊敬的交互为例,设计了基于云模型的三级尊敬分级模型,提出了基于云模型的交互按钮设计方法。提出了尊敬按钮云滴归属算法,使虚拟角色理解尊敬的过程符合人类认知的不确定性;提出了基于二维鞠躬尊敬云的鞠躬控制算法,随机产生鞠躬最大角和低位保持时间,刻画鞠躬表达尊敬的不确定性。算法分析和交互合成效果表明,所提方法能够刻画交互双方对非语言信息理解的模糊性和随机性。

Cloud model based mind interaction between human and virtual role

Non-verbal information such as emotion and motivation has important influence on human-virtual role interaction. This paper proposed a cloud-based human-virtual role interaction model. Taking respect as an example, it designed its cloud model with 3 levels and designed a cloud-based respect button. It also proposed an algorithm for cloud drop membership of respect button. It facilitated virtual role to understand respect extent considering uncertainties existed in human cognition. At last, the paper proposed a bow respect cloud based algorithm to randomly generate maximal bow angle and time pausing at the angle, described uncertainties of bow indicating respect. Analysis of proposed algorithms and synthesized interaction results show that proposed method is able to describe fuzziness and randomness of understanding non-verbal information in the interaction between human and virtual role.
