For a large population of elderly who live alone, a continuous long-term daily monitoring system is critical and imminently needed to enhance the quality of their lives. Continuous monitoring of vitality information (i.e., which area the elder is staying in, the motion state and activity intensity of an elder) is essential for elderly care. In this paper, we use existing commodity Wi-Fi devices to design and implement a long-term device-free human daily vitality system, WiMonitor. Our system can continuously capture the target's vitality information in a multi-room home environment without compromising the privacy of the target. In a continuous 22-day experiment, WiMonitor successfully captures the human vitality information accurately. We believe our system can provide valuable long-term monitoring data for both researchers and health care personnel.
对于大量独居的老年人来说，需要一个持续的长期日常监测系统，以提高他们的生活质量。对活力信息（例如，老年人所处的区域、老年人的运动状态和活动强度）的持续监测对于老年人护理至关重要。在本文中，我们使用现有的商品 Wi-Fi 设备来设计和实现一种长期免设备的人体日常活力系统 WiMonitor。我们的系统可以在多房间家庭环境中连续捕获目标的活力信息，同时不会侵犯目标的隐私。在一个持续 22 天的实验中，WiMonitor 成功地准确捕获了人体活力信息。我们相信我们的系统可以为研究人员和医疗保健人员提供有价值的长期监测数据。
