    Com a Quarta Revolução Industrial, a propagação da Internet das Coisas, o avanço nas áreas de Inteligência Artificial e de Machine Learning até à migração para a Computação em Nuvem, o termo "Ambientes Inteligentes" cada vez mais deixa de ser uma idealização para se tornar realidade. Da mesma forma as tecnologias de Realidade Extendida também elas têm aumentado a sua presença no mundo tecnológico após um "período de hibernação", desde a popularização do conceito de Metaverse assim como a entrada das grandes empresas informáticas como a Apple e a Google num mercado onde a Realidade Virtual, Realidade Aumentada e Realidade Mista eram dominadas por empresas com menos experiência no desenvolvimento de sistemas (e.g. Meta), reconhecimento a nível mundial (e.g. HTC Vive), ou suporte financeiro e confiança do mercado. Esta tese tem como foco o estudo do potencial uso das tecnologias de Realidade Estendida de forma a promover Saúde Verde assim como seu uso em Hospitais Inteligentes, uma das variantes de Ambientes Inteligentes, incorporando Machine Learning e Computer Vision, como ferramenta de suporte e de melhoria de cuidados de saúde, tanto do ponto de vista do profissional de saúde como do paciente, através duma revisão literarária e análise da atualidade. Resultando na elaboração de um modelo conceptual com a sugestão de tecnologias a poderem ser usadas para alcançar esse cenário selecionadas pelo seu potencial, sendo posteriormente descrito o desenvolvimento de protótipos de partes do modelo conceptual para Óculos de Realidade Extendida como validação de conceito.With the Fourth Industrial Revolution, the spread of the Internet of Things, the advance in the areas of Artificial Intelligence and Machine Learning until the migration to Cloud Computing, the term "Intelligent Environments" increasingly ceases to be an idealization to become reality. Likewise, Extended Reality technologies have also increased their presence in the technological world after a "hibernation period", since the popularization of the Metaverse concept, as well as the entry of large computer companies such as Apple and Google into a market where Virtual Reality, Augmented Reality and Mixed Reality were dominated by companies with less experience in system development (e.g. Meta), worldwide recognition (e.g. HTC Vive) or financial support and trust in the market. This thesis focuses on the study of the potential use of Extended Reality technologies in order to promote GreenHealth as well as their use in Smart Hospitals, one of the variants of Smart Environments, incorporating Machine Learning and Computer Vision, as a tool to support and improve healthcare, both from the point of view of the health professional and the patient, through a literature review and analysis of the current situation. Resulting in the elaboration of a conceptual model with the suggestion of technologies that can be used to achieve this scenario selected for their potential, and then the development of prototypes of parts of the conceptual model for Extended Reality Headsets as concept validation

    This research consists in the development an IoT Physical Rehabilitation solution based on wearable devices, combining a set of smart gloves and smart headband for use in natural interactions with a set of VR therapeutic serious games developed on the Unity 3D gaming platform. The system permits to perform training sessions for hands and fingers motor rehabilitation. Data acquisition is performed by Arduino Nano Microcontroller computation platform with ADC connected to the analog measurement channels materialized by piezo-resistive force sensors and connected to an IMU module via I2C. Data communication is performed using the Bluetooth wireless communication protocol. The smart headband, designed to be used as a first- person-controller in game scenes, will be responsible for collecting the patient's head rotation value, this parameter will be used as the player's avatar head rotation value, approaching the user and the virtual environment in a semi-immersive way. The acquired data are stored and processed on a remote server, which will help the physiotherapist to evaluate the patients' performance around the different physical activities during a rehabilitation session, using a Mobile Application developed for the configuration of games and visualization of results. The use of serious games allows a patient with motor impairments to perform exercises in a highly interactive and non-intrusive way, based on different scenarios of Virtual Reality, contributing to increase the motivation during the rehabilitation process. The system allows to perform an unlimited number of training sessions, making possible to visualize historical values and compare the results of the different performed sessions, for objective evolution of rehabilitation outcome. Some metrics associated with upper limb exercises were also considered to characterize the patient’s movement during the session.Este trabalho de pesquisa consiste no desenvolvimento de uma solução de Reabilitação Física IoT baseada em dispositivos de vestuário, combinando um conjunto de luvas inteligentes e uma fita-de-cabeça inteligente para utilização em interações naturais com um conjunto de jogos terapêuticos sérios de Realidade Virtual desenvolvidos na plataforma de jogos Unity 3D. O sistema permite realizar sessões de treino para reabilitação motora de mãos e dedos. A aquisição de dados é realizada pela plataforma de computação Arduino utilizando um Microcontrolador Nano com ADC (Conversor Analógico-Digital) conectado aos canais de medição analógicos materializados por sensores de força piezo-resistivos e a um módulo IMU por I2C. A comunicação de dados é realizada usando o protocolo de comunicação sem fio Bluetooth. A fita-de-cabeça inteligente, projetada para ser usada como controlador de primeira pessoa nos cenários de jogo, será responsável por coletar o valor de rotação da cabeça do paciente, esse parâmetro será usado como valor de rotação da cabeça do avatar do jogador, aproximando o utilizador e o ambiente virtual de forma semi-imersiva. Os dados adquiridos são armazenados e processados num servidor remoto, o que ajudará o fisioterapeuta a avaliar o desempenho dos pacientes em diferentes atividades físicas durante uma sessão de reabilitação, utilizando uma Aplicação Móvel desenvolvido para configuração de jogos e visualização de resultados. A utilização de jogos sérios permite que um paciente com deficiências motoras realize exercícios de forma altamente interativa e não intrusiva, com base em diferentes cenários de Realidade Virtual, contribuindo para aumentar a motivação durante o processo de reabilitação. O sistema permite realizar um número ilimitado de sessões de treinamento, possibilitando visualizar valores históricos e comparar os resultados das diferentes sessões realizadas, para a evolução objetiva do resultado da reabilitação.

    Current physiological sensors are passive and transmit sensed data to Monitoring centre (MC) through wireless body area network (WBAN) without processing data intelligently. We propose a solution to discern data requestors for prioritising and inferring data to reduce transactions and conserve battery power, which is important requirements of mobile health (mHealth). However, there is a problem for alarm determination without knowing the activity of the user. For example, 170 beats per minute of heart rate can be normal during exercising, however an alarm should be raised if this figure has been sensed during sleep. To solve this problem, we suggest utilising the existing activity recognition (AR) applications. Most of health related wearable devices include accelerometers along with physiological sensors. This paper presents a novel approach and solution to utilise physiological data with AR so that they can provide not only improved and efficient services such as alarm determination but also provide richer health information which may provide content for new markets as well as additional application services such as converged mobile health with aged care services. This has been verified by experimented tests using vital signs such as heart pulse rate, respiration rate and body temperature with a demonstrated outcome of AR accelerometer sensors integrated with an Android app
