智能音箱的广泛使用引发了许多隐私问题。虽然到目前为止的工作提供了对用户对这些威胁的看法的理解，但有限的研究集中在我们如何减轻这些担忧，无论是通过重新设计智能扬声器还是通过专门的隐私保护干预措施。在本文中，我们提出了两个隐私保护干预措施的设计和原型设计：“混淆器”的目标是在麦克风禁用录音，和“PowerCut”的目标是禁用电源的智能扬声器。我们提出了我们的研究结果，从技术探测研究涉及24个家庭，与我们的原型互动，主要目标是获得更好的了解设计空间的技术干预，可能会解决这些问题。我们的数据和研究结果揭示了实用性，隐私性和可用性之间的复杂权衡，并强调了多功能，美学，易用性和形状因素的重要性。我们讨论了我们的研究结果对后续干预措施的发展和智能扬声器的未来设计的影响。
The pervasive use of smart speakers has raised numerous privacy concerns. While work to date provides an understanding of user perceptions of these threats, limited research focuses on how we can mitigate these concerns, either through redesigning the smart speaker or through dedicated privacy-preserving interventions. In this paper, we present the design and prototyping of two privacy-preserving interventions: `Obfuscator' targeted at disabling recording at the microphones, and `PowerCut' targeted at disabling power to the smart speaker. We present our findings from a technology probe study involving 24 households that interacted with our prototypes; the primary objective was to gain a better understanding of the design space for technological interventions that might address these concerns. Our data and findings reveal complex trade-offs among utility, privacy, and usability and stresses the importance of multi-functionality, aesthetics, ease-of-use, and form factor. We discuss the implications of our findings for the development of subsequent interventions and the future design of smart speakers.
