为了降低众包的参与门槛，我们推出了twitch众包：通过快速贡献的众包，可以在一两秒内完成。我们推出了 Twitch，这是一款手机应用程序，要求用户每次解锁手机时进行微额贡献。 Twitch 利用了人们在空闲时间看手机的普遍习惯。 Twitch 众包活动的目标包括编写当地人类活动普查、对库存照片进行评级以及从维基百科页面提取结构化数据。我们报告了 Twitch 的现场部署，其中 82 位用户在日常生活中使用手机时做出了 11,240 项众包贡献。 Twitch 活动的中位数仅花费 1.6 秒，与标准的滑动解锁界面相比，解锁速度或认知负荷没有统计上可区分的成本。
To lower the threshold to participation in crowdsourcing, we present twitch crowdsourcing: crowdsourcing via quick contributions that can be completed in one or two seconds. We introduce Twitch, a mobile phone application that asks users to make a micro-contribution each time they unlock their phone. Twitch takes advantage of the common habit of turning to the mobile phone in spare moments. Twitch crowdsourcing activities span goals such as authoring a census of local human activity, rating stock photos, and extracting structured data from Wikipedia pages. We report a field deployment of Twitch where 82 users made 11,240 crowdsourcing contributions as they used their phone in the course of everyday life. The median Twitch activity took just 1.6 seconds, incurring no statistically distinguishable costs to unlock speed or cognitive load compared to a standard slide-to-unlock interface.
