亚马逊Alexa和Google Home等智能语音助手在我们的日常环境中变得越来越普遍。尽管它们有好处，但它们的小型化和嵌入式摄像头和麦克风引起了与监视和窃听有关的重要隐私问题。最近对这些设备附近的人的隐私问题的研究强调了对“有形隐私”的需求，其中控制和反馈机制可以提供更有保证的摄像头或麦克风是“开”还是“关”的感觉。然而，这些装置的当前设计缺乏足够的机制来提供这种保证。为了解决智能语音助手设计中的这一差距，特别是在禁用麦克风的情况下，我们评估了几种包含（或不包含）有形控制和反馈机制的设计。通过比较人们对这些设计的风险，信任，可靠性，可用性和控制的看法，在受试者之间的在线实验（N=261），我们发现，有形的内置物理控制的设备被认为是更值得信赖和可用的比那些无形的机制。我们的研究结果提出了一种有形的，有保证的隐私，特别是在嵌入式麦克风的情况下的方法。
Smart voice assistants such as Amazon Alexa and Google Home are becoming increasingly pervasive in our everyday environments. Despite their benefits, their miniaturized and embedded cameras and microphones raise important privacy concerns related to surveillance and eavesdropping. Recent work on the privacy concerns of people in the vicinity of these devices has highlighted the need for 'tangible privacy', where control and feedback mechanisms can provide a more assured sense of whether the camera or microphone is 'on' or 'off'. However, current designs of these devices lack adequate mechanisms to provide such assurances. To address this gap in the design of smart voice assistants, especially in the case of disabling microphones, we evaluate several designs that incorporate (or not) tangible control and feedback mechanisms. By comparing people's perceptions of risk, trust, reliability, usability, and control for these designs in a between-subjects online experiment (N=261), we find that devices with tangible built-in physical controls are perceived as more trustworthy and usable than those with non-tangible mechanisms. Our findings present an approach for tangible, assured privacy especially in the context of embedded microphones.
