我们提出了一个45名参与者的实验室研究的结果，调查9个工具的可用性，以限制在线行为广告（OBA）。我们就OBA采访了参与者，并记录了他们在配置和使用隐私工具时的行为和态度，例如阻止对特定URL的请求的浏览器插件，设置浏览器cookie以指示用户选择退出OBA的工具，或内置于Web浏览器中的隐私设置。我们在测试的所有工具中发现了严重的可用性缺陷。参与者发现许多工具难以配置，工具的默认设置通常保护性最低。无效的沟通、混乱的界面和缺乏反馈，导致许多参与者得出结论，认为某个工具在他们没有正确配置的情况下阻塞了OBA。由于不熟悉许多广告公司和跟踪技术，参与者很难有效地使用这些工具。
We present results of a 45-participant laboratory study investigating the usability of nine tools to limit online behavioral advertising (OBA). We interviewed participants about OBA and recorded their behavior and attitudes as they configured and used a privacy tool, such as a browser plugin that blocks requests to specific URLs, a tool that sets browser cookies indicating a user's preference to opt out of OBA, or the privacy settings built into a web browser. We found serious usability flaws in all tools we tested. Participants found many tools difficult to configure, and tools' default settings were often minimally protective. Ineffective communication, confusing interfaces, and a lack of feedback led many participants to conclude that a tool was blocking OBA when they had not properly configured it to do so. Without being familiar with many advertising companies and tracking technologies, it was difficult for participants to use the tools effectively.
