Using a fixed camera in the home of a solitary-living elderly person or in a private nursing-home room, the system analyzes daily activity video and detects loneliness-related behaviors: prolonged solitude (no social interaction), static gazing (long-time fixation with no purposeful activity), sighing (rapid chest/abdomen rise-fall with exhale), and talking-to-self (mouth activity with no conversation partner). | 通过独居老人家中或养老院单人房的固定摄像头，分析老人日常行为视频，检测孤独相关行为：长时间独处（无社交互动）、静止发呆（长时间凝视一处无目的活动）、叹气（胸腹快速起伏伴呼气）、自言自语（口部活动但无对话对象）等。
