Office Prolonged Sitting & Posture Warning | 成人久坐/姿态预警（办公室）

Using a fixed camera in the office (aimed at the workstation), the system analyzes office workers' sitting-posture video in real time, detecting continuous sitting duration, neck forward angle (head offset relative to shoulders), and back curvature (hunchback degree). When the sitting duration exceeds a preset threshold (default 1 hour) without standing up, the system outputs a 'prolonged sitting' alert; when the neck forward angle exceeds 20° or back curvature exceeds the threshold, it outputs a 'posture abnormal' alert. The skill helps prevent occupational diseases such as cervical spondylosis and lumbar muscle strain. Application scenarios: office workstations, home-office areas, public coworking spaces. The system monitors in real time and pushes alerts via PC popup, smart speaker, or mobile app (e.g., 'sitting for 1 hour, please stand up' or 'straighten your back'). Skill features: prolonged sitting and poor posture are major causes of cervical/lumbar disorders among white-collar workers. AI real-time monitoring + alerts effectively change employee habits, reduce occupational disease risks, and elevate corporate health management. Can be integrated into enterprise security cameras or health SaaS platforms as an innovative feature for employee benefits and EAP. | 通过办公区固定摄像头（对准工位）实时分析办公人员的坐姿视频，检测连续坐姿时间、颈部前倾角度（头部相对于肩部的偏移）、背部弯曲度（驼背程度）。当久坐时间超过预设阈值（默认1小时）且未起身活动时，输出'久坐提醒'；当颈部前倾角>20°或背部弯曲超过阈值时，输出'姿态异常提醒'。该技能有助于预防颈椎病、腰肌劳损等办公室职业病。应用场景：办公室工位、居家办公区、公共办公空间。系统实时监测，通过PC弹窗、智能音箱或手机APP推送提醒（如'已坐1小时，请起身活动'或'请直起腰背'）。技能特点：久坐和不良坐姿是白领阶层颈椎、腰椎病高发的主要原因。通过AI自动监测并实时提醒，可有效改变员工行为习惯，降低职业病风险，提升企业健康管理水平。该技能可集成到企业安防摄像头或健康SaaS平台中，成为员工福利和EAP（员工援助计划）的创新功能。
