Elderly Facial Asymmetry / Mouth-Corner Deviation Detection | 老年人面部不对称/口角歪斜识别
v1.0.0Using a fixed home camera to capture frontal facial images or short videos of the elderly, the system uses AI facial-landmark detection to analyze features such as the height difference between left/right mouth corners, the symmetry of nasolabial folds (smile lines), and the asymmetry of eyebrow lifts, and computes a facial asymmetry index (0-100%). The skill works as an auxiliary screening tool for stroke prodromal signs, reminding family members or caregivers to pay attention to facial paralysis or mouth-corner deviation and seek timely medical care. Application scenarios: home-based elderly care, nursing homes, community health centers. The system can be scheduled (e.g., daily) or auto-triggered when abnormal behavior is observed; it outputs an asymmetry index and pushes a 'facial asymmetry risk' alert when a threshold is exceeded. Skill features: facial asymmetry is an important early sign of stroke. AI periodic screening helps families detect anomalies in time and preserve the thrombolytic treatment window. Can be integrated into smart cameras or health-management platforms as a practical feature for at-home senior health monitoring. | 通过家庭固定摄像头拍摄老年人正面面部图像或视频，利用AI面部关键点检测技术分析左右嘴角的高度差、鼻唇沟（法令纹）的对称性、眉毛抬高的差异等特征，计算面部不对称指数（0-100%）。该技能可作为脑卒中（中风）前兆的辅助筛查工具，提示家属或护理人员关注老年人是否存在面瘫、口角歪斜等神经系统异常，及时就医。应用场景：居家养老、养老院、社区健康中心。系统可定期（如每天）或在老年人出现异常行为时自动触发检测，输出不对称指数，当超过设定阈值时推送'面部不对称风险'提醒。技能特点：面部不对称是脑卒中的重要早期体征之一。通过AI定期检测，可帮助家属及时发现异常，争取溶栓治疗时间窗。该技能可集成到智能摄像头或健康管理平台中，成为老年人居家健康监测的实用功能。
