近年来，独居老年人的数量快速增长。这增加了对室内医疗服务的需求，帮助老年居民过上安全和独立的生活。人们对室内无处不在的医疗保健(U-Healthcare)应用程序越来越感兴趣，这些应用程序通过传感器以不引人注目的方式监控老年人，并警告他们或医疗保健提供者异常情况。在U-Healthcare应用程序中，自动定位和跟踪在建筑物周围走动的用户是一项基本功能。全球定位系统等室外位置传感技术不适合用于室内环境，如智能家居应用，因为它们基于室内的位置传感缺乏准确性。本文提出了一种利用射频识别技术对老年人进行精确定位和跟踪的室内U-Healthcare系统。拟议的系统提供对老年人行踪的实时监控。此外，它还分析了它们的位置与时隙以及它们在同一位置停留的时间长度，从而推断出运动模式、范围和频率等信息。这些信息被用来确定老年人的幸福感，并警告家庭或医疗工作者任何潜在的问题。拟议的室内U-Healthcare系统提高了向老年人提供护理的质量和便利性。
In recent years, the number of elderly people living alone has grown rapidly. This increases the need for indoor healthcare services that help elderly residents live a safe and independent life. There has been increasing interest in indoor ubiquitous healthcare (U-Healthcare) applications that monitor the elderly unobtrusively via sensors and that warn them or healthcare providers of abnormal conditions. In U-Healthcare applications, automatically locating and tracking users who move around a building is a fundamental feature. Outdoor location sensing technologies such as the global positioning systems are not suitable for use in indoor environments, such as "smart home" applications, because their indoor-based location sensing lacks accuracy. This paper proposes an indoor U-Healthcare system that uses radio-frequency identification technology to accurately locate and track the elderly. The proposed system provides real-time monitoring of elderly people's whereabouts. In addition, it analyzes their locations in association with time slots and the length of time they stay in the same place, thus inferring information such as movement patterns, ranges, and frequencies. This information is used to determine elderly people's well-being and to warn family or healthcare workers of any potential problems. The proposed indoor U-Healthcare system improves the quality and convenience of care delivered to elderly people.
