Online crowdsourcing enables the distribution of work to a global labor force as small and often repetitive tasks. Recently, situated crowdsourcing has emerged as a complementary enabler to elicit labor in specific locations and from specific crowds. Teamwork in online crowdsourcing has been recently shown to increase the quality of output, but teamwork in situated crowdsourcing remains unexplored. We set out to fill this gap. We present a generic crowdsourcing platform that supports situated teamwork and provide experiences from a laboratory study that focused on comparing traditional online crowdsourcing to situated team-based crowdsourcing. We built a crowdsourcing desk that hosts three networked terminal displays. The displays run our custom team-driven crowdsourcing platform that was used to investigate collocated crowdsourcing in small teams. In addition to analyzing quantitative data, we provide findings based on questionnaires, interviews, and observations. We highlight 1) emerging differences between traditional and collocated crowdsourcing, 2) the collaboration strategies that teams exhibited in collocated crowdsourcing, and 3) that a priori team familiarity does not significantly affect collocated interaction in crowdsourcing. The approach we introduce is a novel multi-display crowdsourcing setup that supports collocated labor teams and along with the reported study makes specific contributions to situated crowdsourcing research.

在线众包可将工作分配给全球劳动力，这是一项小规模且经常重复的任务。近来，定位众包已经成为在特定位置和特定人群引诱劳动力的补充推动力。最近显示了在线众包中的团队合作可提高输出质量，但尚不探索在现场众包中的团队合作。我们着手填补这一空白。我们提供了一个通用的众包平台，该平台支持社区团队合作，并提供实验室研究的经验，重点是将传统的在线众包与基于团队的团队众包进行比较。我们建立了一个可容纳三个联网终端显示器的众包服务台。这些显示器运行我们定制的团队驱动的众包平台，该平台用于调查小型团队中并置的众包。除了分析定量数据外，我们还提供基于问卷调查，访谈和观察的结果。我们着重强调1）传统和并置众包之间的新兴差异； 2）团队在并置众包中展示的协作策略；以及3）先验团队的熟悉程度不会显着影响众包中的并置交互。我们介绍的方法是一种新颖的多显示器众包设置，可支持并置的劳动力团队，并且与报告的研究一起为位置众包研究做出了特殊贡献。
