This article presents a case study demonstrating a non-intrusive method for
the well-being monitoring of elderly people. It is based on our real-time
energy measurement system, which uses tiny beacons attached to electricity
meters. Four participants aged 67-82 years took part in our study. We observed
their electric power consumption for approx. a month, and then we analyzed
them, taking into account the participants' notes on their activities. We
created typical daily usage profiles for each participant and used anomaly
detection to find unusual energy consumption. We found out that real-time
energy measurement can give significant insight into someone's daily activities
and, consequently, bring invaluable information to caregivers about the
well-being of an elderly person, while being discreet and entirely
non-intrusive.

该研究通过实时能源测量系统对老年人的日常活动进行监测，使用非侵入性的方法研究了四位年龄在 67-82 岁之间的参与者。通过分析参与者的活动，我们为每个参与者创建了典型的日常用电模式，并使用异常检测技术发现了异常的能源消耗。结果表明，实时能源测量对了解老年人日常活动提供了重要的见解，可以为照顾者提供有价值的信息，并且完全不会侵入老年人的隐私。

老年人非侵入式健康监测的实时能源测量 -- 一个案例研究

Real-Time Energy Measurement for Non-Intrusive Well-Being Monitoring of  Elderly People -- a Case Study

People suffering from Alzheimer's disease (AD) and their caregivers seek
different approaches to cope with memory loss. Although AD patients want to
live independently, they often need help from caregivers. In this situation,
caregivers may attach notes on every single object or take out the contents of
a drawer to make them visible before leaving the patient alone at home. This
study reports preliminary results on an Ambient Assisted Living (AAL) real-time
system, achieved through the Internet of Things (IoT) and Augmented Reality
(AR) concepts, aimed at helping people suffering from AD. The system has two
main sections: the smartphone or windows application allows caregivers to
monitor patients' status at home and be notified if patients are at risk. The
second part allows patients to use smart glasses to recognize QR codes in the
environment and receive information related to tags in the form of audio, text,
or three-dimensional image. This work presents preliminary results and
investigates the possibility of implementing such a system.

利用物联网和增强现实概念创造一种环境辅助生活实施系统，来帮助患有阿尔茨海默症（AD）的人。该系统包括智能手机或 Windows 应用程序和智能眼镜。前者用于监测 AD 患者在家中的状况并在患者处于风险状态时通知看护人员。后者用于识别环境中的二维码，并以格式化音频、文本或三维图像的形式提供相关信息。本文探讨了该系统实施的可能性并报告了初步结果。
