笔记本电脑的网络摄像头可以被恶意软件和执法机构秘密激活。因此，59%的美国人手动盖住他们的网络摄像头以避免被监视。然而，手动保护套很容易出现人为错误——通过对200名用户的调查，我们发现61.5%的用户在使用网络摄像头后偶尔会忘记重新安装保护套。为了解决这个问题，我们开发了智能网络摄像头罩（SWC）：一种薄膜，默认覆盖网络摄像头（pdlc覆盖），直到用户手动打开网络摄像头，并在不使用时自动覆盖网络摄像头。通过两阶段的设计迭代过程，我们通过远程研究与SWC视频原型对20个网络摄像头覆盖用户进行了SWC评估，并与手动操作进行了比较，并讨论了影响用户对SWC有效性信任的因素以及他们对其实用性的看法。
Laptop webcams can be covertly activated by malware and law enforcement agencies. Consequently, 59% percent of Americans manually cover their webcams to avoid being surveilled. However, manual covers are prone to human error---through a survey with 200 users, we found that 61.5% occasionally forget to re-attach their cover after using their webcam. To address this problem, we developed Smart Webcam Cover (SWC): a thin film that covers the webcam (PDLC-overlay) by default until a user manually uncovers the webcam, and automatically covers the webcam when not in use. Through a two-phased design iteration process, we evaluated SWC with 20 webcam cover users through a remote study with a video prototype of SWC, compared to manual operation, and discussed factors that influence users' trust in the effectiveness of SWC and their perceptions of its utility.
