Non-Invasive Ambient Intelligence in Real Life: Dealing with Noisy Patterns to Help Older People
This paper aims to contribute to the field of ambient intelligence from the perspective of real environments, where noise levels in datasets are significant, by showing how machine learning techniques can contribute to the knowledge creation, by promoting software sensors. The created knowledge can be actionable to develop features helping to deal with problems related to minimally labelled datasets. A case study is presented and analysed, looking to infer high-level rules, which can help to anticipate abnormal activities, and potential benefits of the integration of these technologies are discussed in this context. The contribution also aims to analyse the usage of the models for the transfer of knowledge when different sensors with different settings contribute to the noise levels. Finally, based on the authors’ experience, a framework proposal for creating valuable and aggregated knowledge is depicted.This research was partially funded by Fundación Tecnalia Research & Innovation, and J.O.-M. also wants

Indoor Air Quality Monitoring for Enhanced Healthy Buildings
Since most people spend 90% of their time indoors, the indoor environment has a determining influence on human health. In many instances, the air quality parameters are very different from those defined as healthy values. Using real-time monitoring, occupants or the building manager can decide and control behaviors and interventions to improve indoor air quality. The historical database is also useful for assisting doctors to support the medical diagnosis. The continuous technological advancements notably, as regards, networking, sensors, and embedded devices have made it possible to monitor and provide assistance to people in their homes. Smart objects with great capabilities for sensing and connecting could revolutionize the way we are monitoring our environment. This chapter consists of a general overview of several real-time monitoring systems developed and published by the authors. In this chapter, the authors present several new open-source and cost-effective systems that had been developed for monitoring environmental parameters, always with the aim of improving indoor air quality for enhanced healthy buildings
Internet of Things Architectures for Enhanced Living Environments
Ambient Assisted Living (AAL) is an emerging multidisciplinary research area that aims to create
an ecosystem of different types of sensors, computers, mobile devices, wireless networks, and
software applications for enhanced living environments and occupational health. There are
several challenges in the development and implementation of an effective AAL system, such as
system architecture, human-computer interaction, ergonomics, usability, and accessibility.
There are also social and ethical challenges, such as acceptance by seniors and the privacy and
confidentiality that must be a requirement of AAL devices. It is also essential to ensure that
technology does not replace human care and is used as a relevant complement.
The Internet of Things (IoT) is a paradigm where objects are connected to the Internet and
support sensing capabilities. IoT devices should be ubiquitous, recognize the context, and
support intelligence capabilities closely related to AAL. Technological advances allow defining
new advanced tools and platforms for real-time health monitoring and decision making in the
treatment of various diseases. IoT is a suitable approach to building healthcare systems, and it
provides a suitable platform for ubiquitous health services, using, for example, portable sensors
to carry data to servers and smartphones for communication. Despite the potential of the IoT
paradigm and technologies for healthcare systems, several challenges to be overcome still
exist. The direction and impact of IoT in the economy are not clearly defined, and there are
barriers to the immediate and ubiquitous adoption of IoT products, services, and solutions.
Several sources of pollutants have a high impact on indoor living environments. Consequently,
indoor air quality is recognized as a fundamental variable to be controlled for enhanced health
and well-being. It is critical to note that typically most people occupy more than 90% of their
time inside buildings, and poor indoor air quality negatively affects performance and
productivity.
Research initiatives are required to address air quality issues to adopt legislation and real-time
inspection mechanisms to improve public health, not only to monitor public places, schools,
and hospitals but also to increase the rigor of building rules. Therefore, it is necessary to use
real-time monitoring systems for correct analysis of indoor air quality to ensure a healthy
environment in at least public spaces. In most cases, simple interventions provided by
homeowners can produce substantial positive impacts on indoor air quality, such as avoiding
indoor smoking and the correct use of natural ventilation.
An indoor air quality monitoring system helps the detection and improvement of air quality
conditions. Local and distributed assessment of chemical concentrations is significant for safety (e.g., detection of gas leaks and monitoring of pollutants) as well as to control heating,
ventilation, and HVAC systems to improve energy efficiency. Real-time indoor air quality
monitoring provides reliable data for the correct control of building automation systems and
should be assumed as a decision support platform on planning interventions for enhanced living
environments. However, the monitoring systems currently available are expensive and only
allow the collection of random samples that are not provided with time information. Most
solutions on the market only allow data consulting limited to device memory and require
procedures for downloading and manipulating data with specific software. In this way, the
development of innovative environmental monitoring systems based on ubiquitous technologies
that allow real-time analysis becomes essential.
This thesis resulted in the design and development of IoT architectures using modular and
scalable structures for air quality monitoring based on data collected from cost-effective
sensors for enhanced living environments. The proposed architectures address several
concepts, including acquisition, processing, storage, analysis, and visualization of data. These
systems incorporate an alert management Framework that notifies the user in real-time in poor
indoor air quality scenarios. The software Framework supports multiple alert methods, such as
push notifications, SMS, and e-mail. The real-time notification system offers several advantages
when the goal is to achieve effective changes for enhanced living environments. On the one
hand, notification messages promote behavioral changes. These alerts allow the building
manager to identify air quality problems and plan interventions to avoid unhealthy air quality
scenarios. The proposed architectures incorporate mobile computing technologies such as
mobile applications that provide ubiquitous air quality data consulting methods s. Also, the
data is stored and can be shared with medical teams to support the diagnosis.
The state-of-the-art analysis has resulted in a review article on technologies, applications,
challenges, opportunities, open-source IoT platforms, and operating systems. This review was
significant to define the IoT-based Framework for indoor air quality supervision. The research
leads to the development and design of cost-effective solutions based on open-source
technologies that support Wi-Fi communication and incorporate several advantages such as
modularity, scalability, and easy installation. The results obtained are auspicious, representing
a significant contribution to enhanced living environments and occupational health.
Particulate matter (PM) is a complex mixture of solid and liquid particles of organic and
inorganic substances suspended in the air. Moreover, it is considered the pollutant that affects
more people. The most damaging particles to health are ≤PM10 (diameter 10 microns or less),
which can penetrate and lodge deep within the lungs, contributing to the risk of developing
cardiovascular and respiratory diseases as well as lung cancer. Taking into account the adverse
health effects of PM exposure, an IoT architecture for automatic PM monitoring was proposed.
The proposed architecture is a PM real-time monitoring system and a decision-making tool. The
solution consists of a hardware prototype for data acquisition and a Web Framework developed in .NET for data consulting. This system is based on open-source and technologies, with several
advantages compared to existing systems, such as modularity, scalability, low-cost and easy
installation. The data is stored in a database developed in SQL SERVER using .NET Web services.
The results show the ability of the system to analyze the indoor air quality in real-time and the
potential of the Web Framework for the planning of interventions to ensure safe, healthy, and
comfortable conditions.
Associations of high concentrations of carbon dioxide (CO2) with low productivity at work and
increased health problems are well documented. There is also a clear correlation between high
levels of CO2 and high concentrations of pollutants in indoor air. There are sufficient reasons
to monitor CO2 and provide real-time notifications to improve occupational health and provide
a safe and healthy indoor living environment. Taking into account the significant influence of
CO2 for enhanced living environments, a real-time IoT architecture for CO2 monitoring was
proposed. CO2 was selected because it is easy to measure and is produced in quantity (by people
and combustion equipment). It can be used as an indicator of other pollutants and, therefore,
of air quality in general. The solution consists of a hardware prototype for data acquisition
environment, a Web software, and a smartphone application for data consulting. The proposed
architecture is based on open-source technologies, and the data is stored in a SQL SERVER
database. The mobile Framework allows the user not only to consult the latest data collected
but also to receive real-time notifications in poor indoor air quality scenarios, and to configure
the alerts threshold levels. The results show that the mobile application not only provides easy
access to real-time air quality data, but also allows the user to maintain parameter history and
provide a history of changes. Consequently, this system allows the user to analyze in a precise
and detailed manner the behavior of air quality.
Finally, an air quality monitoring solution was implemented, consisting of a hardware prototype
that incorporates only the MICS-6814 sensor as the detection unit. This system monitors various
air quality parameters such as NH3 (ammonia), CO (carbon monoxide), NO2 (nitrogen dioxide),
C3H8 (propane), C4H10 (butane), CH4 (methane), H2 (hydrogen) and C2H5OH (ethanol). The
monitoring of the concentrations of these pollutants is essential to provide enhanced living
environments. This solution is based on Cloud, and the collected data is sent to the ThingSpeak
platform. The proposed Framework combines sensitivity, flexibility, and measurement
accuracy in real-time, allowing a significant evolution of current air quality controls. The results
show that this system provides easy, intuitive, and fast access to air quality data as well as
relevant notifications in poor air quality situations to provide real-time intervention and
improve occupational health. These data can be accessed by physicians to support diagnoses
and correlate the symptoms and health problems of patients with the environment in which
they live. As future work, the results reported in this thesis can be considered as a starting point for the
development of a secure system sharing data with health professionals in order to serve as
decision support in diagnosis.Ambient Assisted Living (AAL) é uma área de investigação multidisciplinar emergente que visa
a construção de um ecossistema de diferentes tipos de sensores, microcontroladores,
dispositivos móveis, redes sem fios e aplicações de software para melhorar os ambientes de
vida e a saúde ocupacional. Existem muitos desafios no desenvolvimento e na implementação
de um sistema AAL, como a arquitetura do sistema, interação humano-computador, ergonomia,
usabilidade e acessibilidade. Existem também problemas sociais e éticos, como a aceitação por
parte dos utilizadores mais vulneráveis e a privacidade e confidencialidade, que devem ser uma
exigência de todos os dispositivos AAL. De facto, também é essencial assegurar que a tecnologia
não substitua o cuidado humano e seja usada como um complemento essencial.
A Internet das Coisas (IoT) é um paradigma em que os objetos estão conectados à Internet e
suportam recursos sensoriais. Tendencialmente, os dispositivos IoT devem ser omnipresentes,
reconhecer o contexto e ativar os recursos de inteligência ambiente intimamente relacionados
ao AAL. Os avanços tecnológicos permitem definir novas ferramentas avançadas e plataformas
para monitorização de saúde em tempo real e tomada de decisão no tratamento de várias
doenças. A IoT é uma abordagem adequada para construir sistemas de saúde sendo que oferece
uma plataforma para serviços de saúde ubíquos, usando, por exemplo, sensores portáteis para
recolha e transmissão de dados e smartphones para comunicação. Apesar do potencial do
paradigma e tecnologias IoT para o desenvolvimento de sistemas de saúde, muitos desafios
continuam ainda por ser resolvidos. A direção e o impacto das soluções IoT na economia não
está claramente definido existindo, portanto, barreiras à adoção imediata de produtos, serviços
e soluções de IoT.
Os ambientes de vida são caracterizados por diversas fontes de poluentes. Consequentemente,
a qualidade do ar interior é reconhecida como uma variável fundamental a ser controlada de
forma a melhorar a saúde e o bem-estar. É importante referir que tipicamente a maioria das
pessoas ocupam mais de 90% do seu tempo no interior de edifícios e que a má qualidade do ar
interior afeta negativamente o desempenho e produtividade.
É necessário que as equipas de investigação continuem a abordar os problemas de qualidade do
ar visando a adoção de legislação e mecanismos de inspeção que atuem em tempo real para a
melhoraria da saúde e qualidade de vida, tanto em locais públicos como escolas e hospitais e
residências particulares de forma a aumentar o rigor das regras de construção de edifícios. Para
tal, é necessário utilizar mecanismos de monitorização em tempo real de forma a possibilitar
a análise correta da qualidade do ambiente interior para garantir ambientes de vida saudáveis.
Na maioria dos casos, intervenções simples que podem ser executadas pelos proprietários ou ocupantes da residência podem produzir impactos positivos substanciais na qualidade do ar
interior, como evitar fumar em ambientes fechados e o uso correto de ventilação natural.
Um sistema de monitorização e avaliação da qualidade do ar interior ajuda na deteção e na
melhoria das condições ambiente. A avaliação local e distribuída das concentrações químicas é
significativa para a segurança (por exemplo, deteção de fugas de gás e supervisão dos
poluentes) bem como para controlar o aquecimento, ventilação, e sistemas de ar condicionado
(HVAC) visando a melhoria da eficiência energética. A monitorização em tempo real da
qualidade do ar interior fornece dados fiáveis para o correto controlo de sistemas de automação
de edifícios e deve ser assumida com uma plataforma de apoio à decisão no que se refere ao
planeamento de intervenções para ambientes de vida melhorados. No entanto, os sistemas de
monitorização atualmente disponíveis são de alto custo e apenas permitem a recolha de
amostras aleatórias que não são providas de informação temporal. A maioria das soluções
disponíveis no mercado permite apenas a acesso ao histórico de dados que é limitado à memória
do dispositivo e exige procedimentos de download e manipulação de dados com software
proprietário. Desta forma, o desenvolvimento de sistemas inovadores de monitorização
ambiente baseados em tecnologias ubíquas e computação móvel que permitam a análise em
tempo real torna-se essencial.
A Tese resultou na definição e no desenvolvimento de arquiteturas para monitorização da
qualidade do ar baseadas em IoT. Os métodos propostos são de baixo custo e recorrem a
estruturas modulares e escaláveis para proporcionar ambientes de vida melhorados. As
arquiteturas propostas abordam vários conceitos, incluindo aquisição, processamento,
armazenamento, análise e visualização de dados. Os métodos propostos incorporam
Frameworks de gestão de alertas que notificam o utilizador em tempo real e de forma ubíqua
quando a qualidade do ar interior é deficiente. A estrutura de software suporta vários métodos
de notificação, como notificações remotas para smartphone, SMS (Short Message Service) e email.
O método usado para o envio de notificações em tempo real oferece várias vantagens
quando o objetivo é alcançar mudanças efetivas para ambientes de vida melhorados. Por um
lado, as mensagens de notificação promovem mudanças de comportamento. De facto, estes
alertas permitem que o gestor do edifício e os ocupantes reconheçam padrões da qualidade do
ar e permitem também um correto planeamento de intervenções de forma evitar situações em
que a qualidade do ar é deficiente. Por outro lado, o sistema proposto incorpora tecnologias
de computação móvel, como aplicações móveis, que fornecem acesso omnipresente aos dados
de qualidade do ar e, consequentemente, fornecem soluções completas para análise de dados.
Além disso, os dados são armazenados e podem ser partilhados com equipas médicas para
ajudar no diagnóstico.
A análise do estado da arte resultou na elaboração de um artigo de revisão sobre as tecnologias,
aplicações, desafios, plataformas e sistemas operativos que envolvem a criação de arquiteturas
IoT. Esta revisão foi um trabalho fundamental na definição das arquiteturas propostas baseado em IoT para a supervisão da qualidade do ar interior. Esta pesquisa conduz a um
desenvolvimento de arquiteturas IoT de baixo custo com base em tecnologias de código aberto
que operam como um sistema Wi-Fi e suportam várias vantagens, como modularidade,
escalabilidade e facilidade de instalação. Os resultados obtidos são muito promissores,
representando uma contribuição significativa para ambientes de vida melhorados e saúde
ocupacional.
O material particulado (PM) é uma mistura complexa de partículas sólidas e líquidas de
substâncias orgânicas e inorgânicas suspensas no ar e é considerado o poluente que afeta mais
pessoas. As partículas mais prejudiciais à saúde são as ≤PM10 (diâmetro de 10 micrómetros ou
menos), que podem penetrar e fixarem-se dentro dos pulmões, contribuindo para o risco de
desenvolver doenças cardiovasculares e respiratórias, bem como de cancro do pulmão. Tendo
em consideração os efeitos negativos para a saúde da exposição ao PM foi desenvolvido numa
primeira fase uma arquitetura IoT para monitorização automática dos níveis de PM. Esta
arquitetura é um sistema que permite monitorização de PM em tempo real e uma ferramenta
de apoio à tomada de decisão. A solução é composta por um protótipo de hardware para
aquisição de dados e um portal Web desenvolvido em .NET para consulta de dados. Este sistema
é baseado em tecnologias de código aberto com várias vantagens em comparação aos sistemas
existentes, como modularidade, escalabilidade, baixo custo e fácil instalação. Os dados são
armazenados numa base de dados desenvolvida em SQL SERVER e são enviados com recurso a
serviços Web. Os resultados mostram a capacidade do sistema de analisar em tempo real a
qualidade do ar interior e o potencial da Framework Web para o planeamento de intervenções
com o objetivo de garantir condições seguras, saudáveis e confortáveis.
Associações de altas concentrações de dióxido de carbono (CO2) com défice de produtividade
no trabalho e aumento de problemas de saúde encontram-se bem documentadas. Existe
também uma correlação evidente entre altos níveis de CO2 e altas concentrações de poluentes
no ar interior. Tendo em conta a influência significativa do CO2 para a construção de ambientes
de vida melhorados desenvolveu-se uma solução de monitorização em tempo real de CO2 com
base na arquitetura de IoT. A arquitetura proposta permite também o envio de notificações em
tempo real para melhorar a saúde ocupacional e proporcionar um ambiente de vida interior
seguro e saudável. O CO2 foi selecionado, pois é fácil de medir e é produzido em quantidade
(por pessoas e equipamentos de combustão). Assim, pode ser usado como um indicador de
outros poluentes e, portanto, da qualidade do ar em geral. O método proposto é composto por
um protótipo de hardware para aquisição de dados, um software Web e uma aplicação
smartphone para consulta de dados. Esta arquitetura é baseada em tecnologias de código
aberto e os dados recolhidos são armazenados numa base de dados SQL SERVER. A Framework
móvel permite não só consultar em tempo real os últimos dados recolhidos, receber
notificações com o objetivo de avisar o utilizador quando a qualidade do ar está deficiente,
mas também para configurar alertas. Os resultados mostram que a Framework móvel fornece não apenas acesso fácil aos dados da qualidade do ar em tempo real, mas também permite ao
utilizador manter o histórico de parâmetros. Assim este sistema permite ao utilizador analisar
de maneira precisa e detalhada o comportamento da qualidade do ar interior.
Por último, é proposta uma arquitetura para monitorização de vários parâmetros da qualidade
do ar, como NH3 (amoníaco), CO (monóxido de carbono), NO2 (dióxido de azoto), C3H8
(propano), C4H10 (butano), CH4 (metano), H2 (hidrogénio) e C2H5OH (etanol). Esta arquitetura é
composta por um protótipo de hardware que incorpora unicamente o sensor MICS-6814 como
unidade de deteção. O controlo das concentrações destes poluentes é extremamente relevante
para proporcionar ambientes de vida melhorados. Esta solução tem base na Cloud sendo que os
dados recolhidos são enviados para a plataforma ThingSpeak. Esta Framework combina
sensibilidade, flexibilidade e precisão de medição em tempo real, permitindo uma evolução
significativa dos atuais sistemas de monitorização da qualidade do ar. Os resultados mostram
que este sistema fornece acesso fácil, intuitivo e rápido aos dados de qualidade do ar bem
como notificações essenciais em situações de qualidade do ar deficiente de forma a planear
intervenções em tempo útil e melhorar a saúde ocupacional. Esses dados podem ser acedidos
pelos médicos para apoiar diagnósticos e correlacionar os sintomas e problemas de saúde dos
pacientes com o ambiente em que estes vivem.
Como trabalho futuro, os resultados reportados nesta Tese podem ser considerados um ponto
de partida para o desenvolvimento de um sistema seguro para partilha de dados com
profissionais de saúde de forma a servir de suporte à decisão no diagnóstico
NILM techniques for intelligent home energy management and ambient assisted living: a review
The ongoing deployment of smart meters and different commercial devices has made electricity disaggregation feasible in buildings and households, based on a single measure of the current and, sometimes, of the voltage. Energy disaggregation is intended to separate the total power consumption into specific appliance loads, which can be achieved by applying Non-Intrusive Load Monitoring (NILM) techniques with a minimum invasion of privacy. NILM techniques are becoming more and more widespread in recent years, as a consequence of the interest companies and consumers have in efficient energy consumption and management. This work presents a detailed review of NILM methods, focusing particularly on recent proposals and their applications, particularly in the areas of Home Energy Management Systems (HEMS) and Ambient Assisted Living (AAL), where the ability to determine the on/off status of certain devices can provide key information for making further decisions. As well as complementing previous reviews on the NILM field and providing a discussion of the applications of NILM in HEMS and AAL, this paper provides guidelines for future research in these topics.Agência financiadora:

Evaluating the Possibility of Integrating Augmented Reality and Internet of Things Technologies to Help Patients with Alzheimer's Disease
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.Comment: 5 pages, 5 figure
Non-Invasive Data Acquisition and IoT Solution for Human Vital Signs Monitoring: Applications, Limitations and Future Prospects
The rapid development of technology has brought about a revolution in healthcare stimulating a wide range of smart and autonomous applications in homes, clinics, surgeries and hospitals. Smart healthcare opens the opportunity for a qualitative advance in the relations between healthcare providers and end-users for the provision of healthcare such as enabling doctors to diagnose remotely while optimizing the accuracy of the diagnosis and maximizing the benefits of treatment by enabling close patient monitoring. This paper presents a comprehensive review of non-invasive vital data acquisition and the Internet of Things in healthcare informatics and thus reports the challenges in healthcare informatics and suggests future work that would lead to solutions to address the open challenges in IoT and non-invasive vital data acquisition. In particular, the conducted review has revealed that there has been a daunting challenge in the development of multi-frequency vital IoT systems, and addressing this issue will help enable the vital IoT node to be reachable by the broker in multiple area ranges. Furthermore, the utilization of multi-camera systems has proven its high potential to increase the accuracy of vital data acquisition, but the implementation of such systems has not been fully developed with unfilled gaps to be bridged. Moreover, the application of deep learning to the real-time analysis of vital data on the node/edge side will enable optimal, instant offline decision making. Finally, the synergistic integration of reliable power management and energy harvesting systems into non-invasive data acquisition has been omitted so far, and the successful implementation of such systems will lead to a smart, robust, sustainable and self-powered healthcare system
