这些数据来自于对“魔镜”的观察，“魔镜”是一套由四个大型公共展示装置组成的、基于手势的互动装置，安装在德国柏林市中心。这些显示器显示了它们面前环境的镜像，并对观众的手势做出光学效果的反应。对观众行为的观察揭示了反复出现的行为模式，比如在经过第一个展示品时扫了一眼，移动手臂以产生一些效果，然后直接接近下面的一个展示品，并将自己定位在展示品的中心。随后，他经常将自己定位在其他显示器的中心，以探索不同效果的可能性，有时还会拍摄照片或视频。从这些观察中，我们推导出了一个基于手势的公共显示系统的交互框架。它描述了通过展示、观看和反应、微妙互动、直接互动、多重互动和后续行动的阶段。通过在2个周末晚上对660名路人的观察，收集了这些行为阶段的定量数据。本文展示了有多少过路人通过了这两个阶段之间的阈值。这个“观众漏斗”应该提供一个框架，鼓励对公共展示系统进行系统调查，并使不同研究之间具有可比性。
Data are presented from observations of Magical Mirrors, a set of four large public displays with gesture-based interaction installed in downtown Berlin, Germany. The displays show a mirror image of the environment in front of them and react with optical effects to the gestures of the audience. Observations of audience behavior revealed recurring behavioral patterns, like glancing at a first display while passing it, moving the arms to cause some effects, then directly approaching one of the following displays and positioning oneself in the center of the display. This was often followed by positioning oneself in the center of the other displays to explore the possibilities of the different effects, and sometimes by taking photographs or videos. From these observations a framework of interaction with gesture-based public display systems was deduced. It describes the phases of passing by a display, viewing & reacting, subtle interaction, direct interaction, multiple interactions, and follow-up actions. Quantitative data of these behavioral phases was collected by observing 660 passers-by on 2 weekend evenings. This article shows how many passers-by pass the thresholds between these phases. This “Audience Funnel” should provide a framework to encourage systematic investigation of public display systems and enable comparability between different studies.
