An Overview of Omnichannel Interaction in Health Care Services

The adoption of omnichannel interaction services in health care can bring significant benefits to both health care institutions and their patients. The ongoing health pandemic caused by coronavirus disease has further emphasized the need for health care providers to implement an omnichannel strategy to provide seamless personalized experiences to their patients through multiple access channels. This study aimed to examine the current state of research on omnichannel interaction services in health care with a focus on the benefits, challenges, and issues that health care institutions may encounter when adopting this strategy. A systematic literature review was conducted to synthesize the current state of research and provide a comprehensive overview of the field. The results of the review were used to perform a strengths, weaknesses, opportunities, and threats analysis of omnichannel services in health care and identify 5 key criteria that health care institutions should consider when implementing an omnichannel strategy. This study contributes to the field by offering an updated and comprehensive understanding of omnichannel interaction services in health care and provides valuable insights for health care providers considering this strategy. The ultimate goal of an omnichannel strategy in health care is to improve patient engagement, increase access to care, and reduce costs while improving communication and collaboration among health care providers. The successful implementation of this strategy requires a well-defined plan, robust technology, infrastructure, data analytics, capabilities, trained professionals, and a basic understanding of the communication channels among patients. The adoption of an omnichannel strategy in health care can lead to new business growth and increased patient engagement, but health care institutions must be properly aligned and patients must be prepared for its implementation.

Survey for Big Data Platforms and Resources Management for Smart Cities

Abstract: Currently, smart cities are a hot topic and their tendency will be to optimize resources and promote efficient strategies for the preservation of the planet as well as to increase the quality of life of its inhabitants. In this sense, this research presents an initial component of investigation about Big Data Platforms for Smart Cities in order to be implemented in integrated and innovative solutions for development in urban centers. For this, a survey was carried out on “Big Data Platforms”, “Data Science Platforms”, “Security & Privacy” and “Resources Management”. The extraction of the results of this research was done through the SCOPUS repository in articles from the last 5 years to conclude what has been done so far and what will be the trends in the coming years, define proposals for possible solutions for smart cities and identify the right technologies for the design of a smart city architecture.

Software tools for conducting real-time information processing and visualization in industry: An up-to-date review

Abstract: The processing of information in real-time (through the processing of complex events) has become an essential task for the optimal functioning of manufacturing plants. Only in this way can artificial intelligence, data extraction, and even business intelligence techniques be applied, and the data produced daily be used in a beneficent way, enhancing automation processes and improving service delivery. Therefore, professionals and researchers need a wide range of tools to extract, transform, and load data in real-time efficiently. Additionally, the same tool supports or at least facilitates the visualization of this data intuitively and interactively. The review presented in this document aims to provide an up-to-date review of the various tools available to perform these tasks. Of the selected tools, a brief description of how they work, as well as the advantages and disadvantages of their use, will be presented. Furthermore, a critical analysis of overall operation and performance will be presented. Finally, a hybrid architecture that aims to synergize all tools and technologies is presented and discussed.

The Intention to Use e-commerce Using Augmented Reality - The Case of IKEA Place

Resume: The evolution of technologies stimulates the e-commerce market. Recently, augmented reality has been creating significant value in the retail sector. This study aims to analyse an application, IKEA Place, which allows consumers to shop online using augmented reality technology without the need for a marker to identify the surface (Markerless Augmented Reality). The model to evaluate this study was based on the constructs of Technology Acceptance Model (TAM) and other models. The sustainability of the study is exploratory and involves identifying whether this application aims to create more confidence and convenience in the acquisition of a product through the support of this technology. The study was carried out in the North of Portugal, obtaining a convenience sampling in the Porto and Braga regions. The results concluded that there are no significant differences based on sociodemographic data, the operating system used, familiarity with the organization related to the intended use. In contrast, technology changes have been found to offer consumers more confidence and convenience of purchase. Significant results were also obtained in terms of user experience, the preference of this application to make online purchases over existing channels, the future use of such technologies by users to purchase a product and the attraction of purchase regarding perceived ease of use of the application under analysis.

Keywords: Augmented reality, e-commerce, TAM, IKEA Place, Intent to use,

A Realidade Aumentada - Aplicação no âmbito Militar e a validação através do Modelo de Aceitação de Tecnologias

Resumo: A Realidade Aumentada (RA) permite construir e adicionar objetos virtuais num espaço real, seja através de vídeo ou de uma projeção numa superfície transparente. A defesa militar está cada vez mais interessada na RA, pois é uma tecnologia que permitir uma melhor visão geral do campo de batalha. Este trabalho reúne informações sobre a RA, sendo apresentadas algumas aplicações da RA no âmbito militar e informações sobre o modelo TAM - Technology Acceptance Model. No âmbito militar o TAM tem sido utilizado em estudos sobre aceitação de uma nova tecnologia projetada para uso em ambiente de treino por alunos militares. Neste trabalho apresenta-se uma solução genérica que permite usar o TAM numa situação de teste de tecnologias de RA no âmbito militar, sendo referidos aspetos relacionados com o quadro de referência e modelo concetual, metodologias de investigação, técnicas de recolha e análise de dados a adotar.

Palavras-chave: Realidade Aumentada, Defesa Militar, Modelo de Aceitação de Tecnologias – TAM.
