Smartphone overuse has many negative effects on human beings. The function App Limits in our phones, which belongs to behavior reinforcement strategies for overcoming problematic smartphone overuse, constrains users by shutting them completely out of an app after a certain period of time. While it has the effectiveness to some extent, lacking procedural detection of problematic behavior always brings about anxiety and depression for users. We proposed App Limits Bar (ALB) to progress the traditional App Limits, aiming to mitigate the negative feelings about using App Limits and enhance users' abilities to manage their time on addictive apps. Meanwhile, we took a three-phase user study to answer whether ALB helps users be more content with using the app limits function and whether ALB performs better than traditional App Limits in terms of reducing usage time and open times on addictive apps. Future work will study the best shape of the edge screen for visualization when the front screen faces us.

应用程序限制栏：克服智能手机过度使用的应用程序限制的进展

智能手机过度使用会对人类造成许多负面影响。我们手机中的“应用程序限制”功能属于行为强化策略，可解决有问题的智能手机过度使用的问题，它会在一段时间后将用户完全关闭应用程序，从而限制了用户的使用。尽管它具有一定程度的效果，但是缺乏对问题行为的程序检测总是会给用户带来焦虑和沮丧。我们提出了App Limits Bar（ALB）来改进传统的App Limits，旨在减轻对使用App Limits的负面感觉，并增强用户管理其上瘾的应用程序的时间的能力。与此同时，我们进行了一个为期三个阶段的用户研究，以回答ALB是否可以通过使用应用程序限制功能帮助用户获得更多内容，以及在减少上瘾应用程序的使用时间和开放时间方面，ALB是否比传统的应用程序限制更好。未来的工作将研究边缘屏幕的最佳形状，以便在正面屏幕面向我们时可视化。
