用公共摄像头玩身体语言游戏，让陌生人互动变有趣。
Love in Action: Gamifying Public Video Cameras for Fostering Social Relationships in Real World
- 玩家分角色发/回应动作请求，通过摄像头捕捉身体语言。
- 27人两周实验后社交友谊显著提升，问卷显示效果明显。
- 首次将公共摄像头用于社交游戏，适合城市公共空间研究者。
本文提出「爱在行动」（Love in Action, LIA），一种基于身体语言的社交游戏，利用公共场所安装的视频摄像头增强现实世界中的社会关系。游戏中，参与者扮演双重角色：请求者发出社交请求，表演者通过完成指定身体语言来响应。为实现参与者间沟通，我们构建了融合多人检测、属性识别和动作识别等模块的AI增强视频分析系统，以评估表演者身体语言的质量。一项为期两周的实地研究共招募27名参与者，结果显示其社交友谊显著改善，自评问卷数据证实了这一成效。同时，用户经验调研揭示了公共摄像头作为新型社交媒介在公共场所的应用潜力。
原文摘要 · Abstract (English)
In this paper, we create "Love in Action" (LIA), a body language-based social game utilizing video cameras installed in public spaces to enhance social relationships in real-world. In the game, participants assume dual roles, i.e., requesters, who issue social requests, and performers, who respond social requests through performing specified body languages. To mediate the communication between participants, we build an AI-enhanced video analysis system incorporating multiple visual analysis modules like person detection, attribute recognition, and action recognition, to assess the performer's body language quality. A two-week field study involving 27 participants shows significant improvements in their social friendships, as indicated by self-reported questionnaires. Moreover, user experiences are investigated to highlight the potential of public video cameras as a novel communication medium for socializing in public spaces.
