Anxiety-Related Behavior Recognition (Hand-rubbing / Nail-biting / Pacing) | 焦虑症相关行为（搓手、咬指甲、来回踱步）识别

About this Skill

Using a fixed camera at home or in the office, the system analyzes daily videos of an individual (e.g., adult, adolescent) and detects anxiety-related behaviors: hand rubbing (repeated rubbing of both hands), nail biting (hand approaching mouth with biting motion), and pacing (repeated back-and-forth walking in a small area). | 通过家庭或办公室的固定摄像头，分析个体（如成人、青少年）的日常行为视频，检测手部搓揉（双手反复摩擦）、指甲啃咬（手部靠近嘴部并有啃咬动作）、来回踱步（在狭小区域内反复折返行走）等焦虑相关行为。系统实时监测，当焦虑行为指数超过阈值时推送提醒（如'您今日焦虑行为较多，建议进行放松练习'）。
