Pregnancy Emotion Soothing | 孕妇情绪波动舒缓

Through fixed cameras (and optional microphones) at the pregnant woman's home or prenatal exam waiting room, the system analyzes facial expressions (sudden crying, frowning, anxiety), prolonged silent sitting (≥ 30 consecutive minutes without social interaction or activity), and tone of conversations with family members (rapid, impatient). | 通过孕妇家中或产检候诊室的固定摄像头（及可选麦克风），分析孕妇的面部表情（突然哭泣、皱眉、焦虑）、长时间静坐不语（连续超过30分钟无社交互动或活动）、以及与家人对话的语气（急促、不耐烦）。当检测到显著情绪波动时，自动触发安抚动作：通过智能音箱播放孕期舒缓音乐或正念引导音频，或向丈夫手机APP推送提醒（'妻子情绪波动，请打电话关心'）。
