Student Classroom Engagement Analysis | 学生课堂情绪参与度分析

Using a fixed classroom camera, the system analyzes students' facial expressions (focused, confused, happy, frustrated, bored, etc.), computes a class-level overall engagement score (0-100), and can identify low-engagement student positions (no identity stored — for real-time teacher reminders only). Real-time analysis provides engagement heatmaps and abnormal alerts. | 通过教室固定摄像头，分析学生面部表情（专注、困惑、开心、沮丧、无聊等），计算班级整体参与度评分（0-100分），并可识别出参与度较低的学生个体（不存储身份，仅用于实时提醒）。该技能可辅助教师调整教学节奏，关注学习困难学生。
