消费者睡眠跟踪设备为了解个人睡眠习惯提供了一种不引人注目且负担得起的方式。最近的研究主要集中在这类设备提供的信息，即信息是否准确和对人有意义。然而，人们如何判断这些信息的可信度，以及功能和设计可能如何影响这些判断，我们知之甚少。因此，这项研究的目的是检查消费者如何评估睡眠跟踪设备的可信度。我们对22名参与者进行了一项定性研究，他们使用三种不同的设备跟踪他们的睡眠3个晚上：Fitbit Charge 2，NeuroOn EEG和SleepScope，医学睡眠监测器。基于半结构化访谈，我们发现，人们评估睡眠跟踪设备的可信度不仅基于睡眠数据本身的可信度，还取决于设备的功能、界面设计和物理外观。人们发现很难判断可信度，因为睡眠阶段和微唤醒的复杂性(睡眠谬误)和设备的黑箱性质(黑箱谬误)，也因为客观睡眠指标和主观睡眠质量之间的不一致。我们讨论了设计和功能对个人健康技术可信度的重要性，并强调了提高其可信度的设计挑战和机会。
Consumer sleep-tracking devices provide an unobtrusive and affordable way to learn about personal sleep habits. Recent research focused primarily on the information provided by such devices, i.e., whether the information is accurate and meaningful to people. However, little is known about how people judge the credibility of such information, and how the functionality and the design may influence such judgements. Hence, the aim of this research was to examine how consumers assess the credibility of sleep-tracking devices. We conducted a qualitative study with 22 participants who tracked their sleep for 3 nights with three different devices: Fitbit Charge 2, Neuroon EEG, and SleepScope, a medical sleep monitor. Based on semi-structured interviews, we found that people assess the credibility of sleep-tracking devices based not only on the credibility of sleep data per se, but also on device functionality, interface design and physical appearance. People found it difficult to judge credibility, because of the complexities of sleep stages and micro-arousals (sleep fallacy) and the black boxed nature of devices (black box fallacy), and also because of the misalignment between objective sleep measures and subjective sleep quality. We discuss the significance of design and functionality on the credibility of personal health technologies and highlight design challenges and opportunities to enhance their credibility.
