摘　　要：设计了一个以情感交互为核心的人性化的教学辅助系统。该系统综合了情感计算、计算机图形图像技术和移动Agent技术。系统以心理学和人工心理理论为基础构建了情感认知模型,定义了情绪空间、基本情绪和基本学习心理状态,并建立了基本情绪和基本学习心理状态与情绪空间的映射关系。通过情感认知模型对识别表情的处理,得到学生的学习心理状态及状态评价值。采用基于图像处理的人脸检测、表情识别和姿态识别方法编程实现了教学辅助系统。Based on Psychology and the theory of Artificial Psychology, a humanistic computer teaching system was presented. The core of this system was the affective interaction between teacher and student. An emotion-learning model was developed. Emotion space, four kinds of basic emotion and basic learning psychology were defined according to the emotion psychology theory in this model. The mapping between emotion and learning psychology was also established. The student＇ s psychology could get through the expression being processed by affective model, and the psychology could be evaluated to get a value for teacher. Finally, this system was realized by using the recognition method that was based on digital image processing technology.
