- Intangible approaches to improve individual health indicators and empower caregiversPublication . Cunha, Carlos R.; Moreira, André Silva; Pires, Luís; Fernandes, Paula OdetePopulations worldwide are ageing at a faster pace than in the past, and this demographic transition will affect almost all aspects of society [1]. The number and proportion of people aged 60 years and more in the population are increasing; in 2019, the number of people aged 60 years and older was one billion; this number will increase to 1.4 billion by 2030 and 2.1 billion by 2050 [2]. Population ageing is an irreversible worldwide trend. This is the inevitable result of demographic transition, the trend towards longer lives and smaller families, which occurs even in countries with relatively young populations. In 2021, one in ten people worldwide was aged 65 and over; by 2050, this age group is forecasted to represent one in six people worldwide [3]. Globally, the number of people aged 80 years and over is increasing even faster than the number of people aged 65 years and over. By 2050, the world will have an estimated 459 million people aged 80 years and over, which is nearly triple the number in 2021, at approximately 155 million [3]. This finding was seen in all regions of the world where the number of older people increased rapidly between 1980 and 2021, a trend that is likely to continue for the next three decades [3]; even in Portugal, the proportion of older people as in other countries has been increasing steadily over the past decades. By 2050, Portugal expects an old-age dependency rate of 68.8%, which is one of the highest ratios in Europe [4]. The North interior of Portugal, namely, Terras de Trás-os-Montes, is following the same behaviour as what is being observed in the world and in Portugal. Since it is a region located in the northern interior of Portugal and is considered a region of low population density, it has been seeing an increase in the ageing index, and the ageing trends are evident. It is highlighted that in 2021, Terras de Trás-osMontes’ region presents an ageing index of 359.0.
- The use of extended reality and machine learning to improve healthcare and promote greenhealthPublication . Moreira, André Silva; Cunha, Carlos R.; Lopes, Rui PedroCom 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.
- Leveraging the promotion of tourist destinations and the interpretation of their heritage using virtual realityPublication . Cunha, Carlos R.; Mendonça, Vítor; Gomes, João Pedro; Morais, Elisabete Paulo; Moreira, André SilvaTechnology is increasingly a transversal layer to all activities and, in this sense, exploring the potential of technology as a driver to support the competitiveness of organizations and nations has become a necessity for survival. Tourism is a fundamental asset in many modern economies and certainly fundamental from a civilizational and generational point of view, insofar as associated with a wide range of tourist destinations is its heritage. As such, the promotion and interpretation of destinations and their heritage are very important and, in these areas, technologies have played a fundamental and revolutionary role. In this scenario, Virtual Reality, among other technologies, demonstrates a vast potential in promoting tourist destinations and in creating immersive experiences that allow for a better interpretation of destinations and their heritage, as well as greater attractiveness for younger generations. This article, after a review of technological concepts and a discussion of their role in the context of tourism and heritage, proposes a conceptual model capable of contributing to a more agile and massified creation of Virtual Reality experiences. Finally, an experimental prototype created for an olive and olive-oil museum is presented, with the aim of facilitating the interpretation, by visitors, of its permanent exhibition objects and improving the visiting experience.
- Converging extended reality and Machine Learning to improve the lecturing of geometry in basic educationPublication . Cunha, Carlos R.; Moreira, André Silva; Coelho, Sílvia; Mendonça, Vítor; Gomes, João PedroTechnology is constantly supporting in the innovation of the teaching-learning process. Today’s students are more demanding actors when it comes to the environment they have at their disposal to learn, experiment and develop their critical thinking. The area of Mathematics has successively suffered from students’ learning difficulties, whether due to lack of motivation, low abstraction ability or lack of new tools for teachers to bring innovation into the classroom and outside it. While being true that digitalization has entered schools, it often follows a basic and simple process of digital replication of approaches and materials that were previously only available on physical media. This work focuses on the use of Extended Realities, more precisely, Mixed Reality, for teaching Mathematics, and very particularly in the teaching of Geometry, through the proposition of a conceptual model that combines the use of Extended Reality and Machine Learning. The proposed model was subject to prototyping, which is presented as a form of laboratory validation as a contribution to innovate the way of how the geometry teaching-learning process is developed and to promote the integration of Extended Reality technologies into the Education Sector as practical tools, as well due to its potential use to obtain useful insights for teachers, and students, throughout the process.

- Using virtual reality in museums to bridge the gap between material heritage and the interpretation of its immaterial contextPublication . Cunha, Carlos R.; Mendonça, Vítor; Moreira, André Silva; Gomes, João Pedro; Carvalho, AidaMaterial heritage typically has a whole set of associated immaterial heritage, which is essential to pass on to the visitor as a cultural mission of the destinations and those who manage them. In this sense, the interpretation of material heritage is a complex process that is not a fully efficient process with the mere observation of physical artifacts. In this context, it emerges as fundamental to provide visitors with a set of tools that allow them to correctly interpret the artifacts that come to fully understand the cultural dimension of the destinations and their heritage. Accordingly, the role of virtual reality can leverage the creation of innovative and immersive solutions that allow the visitor to understand and feel part of their own heritage and its ancestral component that defines the sociocultural roots of destinations and their civilizational traditions. This article, after dissecting and substantiating the role of virtual reality in the interpretation of heritage, presents a conceptual model, based on the use of virtual reality, which was, in part, prototyped in the scenario of the Portuguese Museum in the city of Miranda do Douro. This proposal is an ongoing contribution to the creation of innovative and immersive tools for the interpretation of heritage.
- The use of virtual reality to boost the promotion of touristic destinations and the interpretation of heritagePublication . Cunha, Carlos R.; Mendonça, Vítor; Gomes, João Pedro; Morais, Elisabete Paulo; Moreira, André SilvaTourism and heritage are fundamental assets in many modern economies and certainly fundamental from a civilizational and generational point of view.

- Using mixed reality and machine learning to assist caregivers in nursing home and promote well-beingPublication . Cunha, Carlos R.; Moreira, André Silva; Pires, Luís; Fernandes, Paula OdeteThe aging phenomenon in many of the developed countries all over the world, combined with the increase in life expectancy, has led to an increase in the number of elderly people resorting to nursing homes. In this context, the role of the caregiver is now a focus of increasing importance. The idea of well-being combined with health and the provision of highly personalized quality care, requires a reengineering of the current concept/space of a nursing home. In this domain, Mixed Reality and Machine Learning have shown enormous potential to design new approaches to Information Systems to support caregiver activity. This redesign should be based on the empowerment of the caregiver and the facilitation of a more immersive support system for their activity and more suitable for a job that is in the field and not in the office, enabling them in real time with decision support information. This article, after an introduction to the reality of aging and the concept of the nursing home, makes a review of the state of the art of what has been the introduction of technology in nursing homes. As a contribution, this work proposes a model based on the combined use of Mixed Reality and Machine Learning, capable of redesigning the way caregivers are helped by empowering them.
