Child Social Interaction Frequency & Duration Analysis | 儿童社交互动频次与时长分析

Using fixed cameras in kindergartens or early-education centers, the system analyzes multi-person video to detect social-interaction behaviors among children, including approach (distance < 1 m), conversation (face-to-face with mouth movement), and cooperative play (collaborative play, chasing, etc.). It counts the number of interactions, total duration, and initiator (the child who actively approaches or initiates the activity) for each pair of children and generates a social-interaction report. The skill helps teachers understand the development of children's social abilities and identify isolated or excluded children. Application scenarios: kindergartens, early-education centers, playgrounds. The system periodically generates social-interaction heatmaps as a reference for teachers. Skill features: a reference for early screening of autism spectrum tendencies. | 通过幼儿园或早教中心的固定摄像头，分析多人视频，检测儿童之间的社交互动行为，包括接近（距离<1米）、对话（面对面且嘴部运动）、共同游戏（合作玩耍、追逐等）。统计每对儿童之间的互动次数、总时长、发起方（主动接近或发起游戏的一方），生成社交互动报告。该技能有助于教师了解儿童的社交能力发展，识别孤僻或被排斥的儿童。应用场景：幼儿园、早教中心、游乐场。系统定期生成社交互动热力图，为教师提供参考。技能特点：孤独症早筛参考。
