Abstract

Consumer sleep tracking technologies offer an unobtrusive and cost-efficient way to monitor sleep in free-living conditions. Technological advances in hardware and software have significantly improved the functionality of the new gadgets that recently appeared in the market. However, whether the latest gadgets can provide valid measurements on overall sleep parameters and sleep structure such as deep and REM sleep has not been examined. In this study, we aimed to investigate the validity of the latest consumer sleep tracking devices including an activity wristband Fitbit Charge 2 and a wearable EEG-based eye mask Neuroon in comparison to a medical sleep monitor. First, we confirmed that Fitbit Charge 2 can automatically detect the onset and offset of sleep with reasonable accuracy. Second, analysis found that both consumer devices produced comparable results in measuring total sleep duration and sleep efficiency compared to the medical device. In addition, Fitbit accurately measured the number of awakenings, while Neuroon with good signal quality had satisfactory performance on total awake time and sleep onset latency. However, measuring sleep structure including light, deep, and REM sleep remains to be challenging for both consumer devices. Third, greater discrepancies were observed between Neuroon and the medical device in nights with more disrupted sleep and when the signal quality was poor, but no trend was observed in Fitbit Charge 2. This study suggests that current consumer sleep tracking technologies may be immature for diagnosing sleep disorders, but they are reasonably satisfactory for general purpose and non-clinical use.

消费者活动腕带和可佩戴脑电图在自由生活条件下测量整体睡眠参数和睡眠结构的有效性
消费类睡眠跟踪技术为自由生活条件下的睡眠监测提供了一种不显眼且经济高效的方式。硬件和软件方面的技术进步极大地改进了最近出现在市场上的新型小工具的功能。然而,最新的小工具是否能有效测量整体睡眠参数和睡眠结构,如深度睡眠和快速动眼期睡眠,尚未进行研究。在这项研究中,我们旨在调查最新的消费类睡眠跟踪设备(包括活动腕带 Fitbit Charge 2 和基于脑电图的可穿戴眼罩 Neuroon)与医疗睡眠监测仪相比的有效性。首先,我们证实 Fitbit Charge 2 可以自动检测睡眠的开始和结束,准确性相当高。其次,分析发现这两款消费类设备在测量总睡眠时间和睡眠效率方面的结果与医疗设备相当。此外,Fitbit 能准确测量觉醒次数,而信号质量较好的 Neuroon 在总清醒时间和睡眠开始潜伏期方面的表现也令人满意。不过,测量睡眠结构(包括浅睡眠、深睡眠和快速动眼期睡眠)对这两种消费类设备来说仍是一项挑战。第三,在睡眠中断较多的夜晚和信号质量较差的情况下,Neuroon 和医疗设备之间的差异较大,但 Fitbit Charge 2 没有观察到这种趋势。这项研究表明,目前的消费类睡眠跟踪技术在诊断睡眠障碍方面可能还不成熟,但在一般用途和非临床使用方面还算令人满意。
