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). It computes a composite loneliness index (0-100). When the index exceeds a threshold, warm-companionship actions are automatically triggered: playing pre-recorded warm voice messages from children via smart speakers, playing the elder’s favorite old songs, or pushing reminders to the children’s mobile app (e.g., ‘Dad seems lonely today — a video call is recommended’). The skill aims to relieve loneliness and improve mental well-being. Application scenarios: homes of solitary-living elderly, private nursing-home rooms, community day-care centers. The system monitors in real time and intervenes proactively when the loneliness index exceeds threshold. Skill features: chronic loneliness is a major risk factor for depression and cognitive decline in older adults. AI auto-identification of loneliness signals followed by timely voice care or reminders to children can effectively alleviate negative emotions and improve quality of life. Can be integrated into smart cameras or elderly-care service platforms as a key emotional-support feature of ‘smart aging’.
CPU 利用率:别被 100% 骗了
CPU 利用率,说白了就是 CPU 忙活的时间占比。但这里有个坑——忙活不等于干活。
我习惯把 CPU 时间分成几类: user:跑用户态程序,比如你的 Java 应用、Python 脚本。 system:内核在干活,比如系统调用、中断处理。 iowait:CPU 在等磁盘或网…...
