Ambient assisted living aims to support the well-being of people with special needs by offering assistive solutions. Systems focused on dementia increase the autonomy of people living with dementia by monitoring their activities. Topics such as activity recognition and specific solutions such as reminders and tracking users by Global Positioning System offer great advances in user safety and help them preserve a healthier lifestyle. However, these solutions are often addressed to secondary parties, providing them activity logs or alerts, but excluding the main user, the person living with dementia. Although the primary users are taken into consideration at some design stages using user-centred design frameworks, the final products tend to not fully address user needs. This paper presents an ambient intelligent system aimed at reducing this limitation by providing reminders and advice to the person living with dementia in the first instance. The system still involves caregivers if unusual or unhealthy behaviour continues. The solution is deployed in order to be validated by professionals from London city boroughs who work in housing and dementia related services, with an emphasis on enhancing healthy lifestyles by empowering the user in the early stages of dementia with autonomy. Through continued activity monitoring in real-time, the system can provide reminders and warnings to users to keep healthy routines. Continuous monitoring provides user behaviour tracking, and the context-aware logic used involves caregivers through alerts when necessary to ensure user safety. This article describes the process followed in developing the system, and covers previous concerns and practical feedback from health professionals over the deployment of the system in a real environment. Our approach also includes a novel indoor localization system to distinguish users and allows a more specific delivery of services in multi-occupancy scenarios.

环境辅助生活旨在通过提供辅助解决方案来支持有特殊需要的人们的幸福。专注于痴呆症的系统通过监视其活动来提高痴呆症患者的自主权。诸如活动识别之类的主题以及诸如全球定位系统的提醒和跟踪用户之类的特定解决方案之类的主题，在用户安全方面取得了长足的进步，并帮助他们保持了健康的生活方式。但是，这些解决方案通常针对次级方，向他们提供活动日志或警报，但不包括主要用户，痴呆症患者。尽管在某些设计阶段使用以用户为中心的设计框架考虑了主要用户，但最终产品往往无法完全满足用户需求。本文提出了一种环境智能系统，旨在通过首先向痴呆症患者提供提醒和建议来减少这种限制。如果异常或不健康行为继续存在，系统仍将涉及看护者。部署该解决方案的目的是要获得来自伦敦市区行政管理部门的专业人员的验证，这些专业人员从事与住房和痴呆有关的服务，重点是通过赋予痴呆症早期阶段的用户自主权来增强健康的生活方式。通过持续的实时活动监视，系统可以向用户提供提醒和警告，以保持健康的例行程序。持续监视提供了用户行为跟踪，并且在必要时使用警报的看护者来确保照护者的安全，以确保用户安全。本文介绍了开发系统所遵循的过程，并涵盖了以前的关注点以及健康专家在实际环境中对系统部署的实际反馈。我们的方法还包括新颖的室内定位系统，以区分用户并允许在多人入住的情况下提供更具体的服务。
