虚拟人情绪模型研究的现状和问题

The present situation and problems with research of a virtual human's emotion

情绪体验能够有效地提高虚拟现实系统用户的兴趣,虚拟人的情绪设计正成为构建虚拟环境的一项核心技术,目前的虚拟人情绪模型仍然处于初级阶段.综述了情绪模型的研究,讨论了情绪模型尚未解决的问题.根据情绪模型相关研究和认知科学的成果,提出了建立虚拟人情绪模型的一种新思,其目标是提高虚拟人情绪设计的效率,虚拟人的情绪状态通过情绪模型来控制,虚拟人可以具有感知、动机、情绪、个性,并可在虚拟环境中表现出恰当的自主情绪.情绪设计软件可以融合软计算理论和人机交互技术,为建立人性化的图形界面提供一种高效工具.

Emotion experience can effectively enhance the interest of users for virtual reality; emotion design for a virtual human is becoming a core technology in building a virtual environment, although the current emotion model of virtual humans is still in a preliminary stage. The previous research on emotion models was reviewed in this paper, and some unsettled problems of the emotion model were discussed. Based on the relative research on emotion models and the achievements of cognitive science, a new idea of building an emotion model was presented for the purpose of improving the efficiency of emotion design for a virtual human. A virtual humang emotion state can be controlled by an emotion model, which has perception, motivation, emotion, and personality while showing appro- priate autonomous emotions in a virtual environment. Emotion design software can integrate the soft-computing theory and human-Computer interaction technology, providing an efficient tool for the establishment of human-oriented graphics interfaces.
