Notification badges are an unexplored category of visual feedback to which we are continuously exposed. This study aims to deepen knowledge on the topic by measuring the behavioral effects of notification badges on a large sample of smartphone users. More precisely, the goal of the study is to observe if the presence of notification badges increases the frequency of clicks on apps. More than 1000 participants were involved in a remote between-subjects experiment, allocated into fifteen equinumerous groups of comparison. Each participant was presented with a smartphone screen displaying fifteen app icons and just one badge notification. Participants were asked to perform a remote user test called First Impression Click Test: a methodology that indicates where they would click first to accomplish a given task (i.e., Where would you click first on this screen?). Our results show a large increase in the number of clicks on apps with notification badges compared to those without notification badges and suggest the important ability of these small affordances to attract attention and stimulate action. Based on the evidence provided, our findings have practical implications for user experience design.
通知徽章是一种尚未被充分研究的视觉反馈类别，我们会不断接触到这类反馈。本研究旨在通过对大量智能手机用户进行研究，深入了解通知徽章的行为效果。更确切地说，本研究的目的是观察通知徽章的存在是否会增加应用程序的点击频率。超过 1000 名参与者参与了一项远程被试间实验，被分配到 15 个相等数量的比较组中。每个参与者都在智能手机屏幕上看到了十五个应用程序图标和一个通知徽章。参与者被要求进行远程用户测试，称为第一印象点击测试：一种指示他们将首先点击何处以完成给定任务的方法（即，您将首先点击屏幕上的何处？）。我们的研究结果表明，带有通知徽章的应用程序的点击次数与没有通知徽章的应用程序相比有了大幅增加，这表明这些小提示具有吸引注意力和激发行动的重要能力。基于提供的证据，我们的研究结果对用户体验设计具有实际意义。
