在线学习系统中情感识别模块的设计与实现

Design and Implementation about Emotion Recognition Module of Online Learning System

针对目前在线学习中存在的“情感缺失”现象，该文结合建构主义、后现代主义教育理论的思想，提出一种具有情感状态评价和教学流程再造功能的在线学习系统模型。本原型系统利用表情识别和疲劳状态检测等技术设计并实现了情感识别模块，该模块注重教学过程中学习者的情绪情感，较好的实现了情感状态评价功能，增强了在线学习环境中的情感互动，为在线学习系统动态地进行教学流程再造提供了技术支撑。

In view of the issue of “emotion absence” in online learning， this paper combined with the educational theory of constructivism and postmodernism， put forward a kind of online learning system model with emotional state evaluation and learning process reengineering function. The emotion recognition module， which is implemented by facial expression recognition and fatigue detection technology， paid attention to the learners’ emotional state during the learning process and achieved a favorable emotional state evaluation effect. The prototype system enhanced the emotional interaction in online learning and provided technical support for dynamically achieving teaching process reengineering in online learning system.
