Commuter After-Work Fatigue Care (Home-Arrival Moment) | 上班族下班疲劳关怀（回家时刻）
v1.0.0Through a fixed camera in a smart-home living room, the system analyzes office worker behavior in the first 30 minutes after coming home, detecting slumped sitting / reclining (relaxed posture, back-to-sofa angle > 120°), facial fatigue features (visible eye bags, downturned mouth corners, frequent blinking), and sighing frequency (rapid chest/abdomen rise-fall with audible exhale). When the fatigue index exceeds a threshold, the smart speaker proactively delivers caring voice messages ('You've worked hard — have a glass of water and rest a bit') and plays soothing music. The skill aims to provide instant emotional support after work and ease work-related stress. Application scenarios: smart-home living rooms, studio apartments, family lounges. The system automatically activates 'care mode' when the user comes home. Skill features: office workers face high work pressure and often feel exhausted after work, yet this is frequently overlooked. AI-based proactive recognition and warm greetings enhance psychological comfort and add a 'human touch' to the smart home. Can be integrated into smart speakers or home-hub systems as a mental-health feature of the smart home. | 通过智能家居客厅的固定摄像头，分析上班族回家后30分钟内的行为，检测瘫坐/斜躺（姿态放松、背部与沙发夹角>120°）、面部疲惫特征（眼袋明显、嘴角下垂、频繁眨眼）、叹气频次（胸腹快速起伏伴呼气声）。当疲劳指数超过阈值时，通过智能音箱主动播报关怀语音（如'辛苦了，喝杯水休息一下'），并播放舒缓音乐。该技能旨在为下班后的用户提供即时的情感支持，缓解工作压力。应用场景：智能家居客厅、单身公寓、家庭起居室。系统在用户回家后自动启动关怀模式。技能特点：上班族工作压力大，回家后常感到疲惫，但往往被忽视。通过AI主动识别并给予温暖问候，可提升心理舒适感，增强智能家居的'人情味'。该技能可集成到智能音箱或家庭中枢系统中，成为智慧家庭的情感健康功能。
