数字娱乐领域中的虚拟人情绪表现模型研究

Research on Virtual Human’s Emotion Expression Model in Field of Digital Entertainment

数字娱乐的本质是创造用户的情绪体验,构造具有情绪表现力的虚拟人是数字娱乐领域的关键目标。虚拟人是完全由计算机系统生成的三维图形实体,他们能够在虚拟世界中模拟真人的各种特征。讨论了数字娱乐领域对虚拟人情绪表现模拟的需求,概括了国际上虚拟人情绪模型的研究现状,提出了虚拟人情绪表现模型研究的一些新方向。可以将虚拟人视为一个智能主体,将虚拟人的情绪表现模型和认知活动结合起来。为了充分地描述情绪决策过程中信息的不确定性,应采用软计算方法,建立虚拟人情绪表现模型。

The essence of digital entertainment is creating emotion experience of users, so constructing virtual human with emotion expression is the key goal in digital entertainment field. Virtual human are three dimension graphics entities, totally produced by computer system, and they can simulate various kinds of characteristics of real human in a virtual world. The requirement of emotion simulation for virtual human was discussed, and the current research of emotion expression in the world was also summarized, and some new research directions of emotion expression model for virtual human were proposed. A virtual human is regarded as an agent with built-in cognitive model that integrates emotion model and cognitive process together. In order to describe the uncertainty of information in the process of emotion decision, emotion expression model should be set up with soft computing method.
