Impacts of Augmented Reality in E-commerce: Advances and Trends in 2024—A Literature Review

This literature review explores recent advancements in the application of augmented reality (AR) within e-commerce, with a specific focus on consumer behavior and technological integration in 2024. AR has emerged as a transformative technology, enabling immersive shopping experiences that allow consumers to virtually interact with products, enhancing their decision-making process. The review analyzed 11 studies published in 2024, highlighting key trends such as the personalization of recommendations through the integration of artificial intelligence (AI), the impact of sensory perceptions on impulsive buying, and the barriers to AR adoption in developing markets. The methodology followed a systematic approach, with articles sourced exclusively from the SCOPUS database and filtered by relevance based on keywords and open-access criteria. The results indicate that AR positively influences purchase intentions boosting consumer confidence through enhanced visual and interactive experiences. However, challenges remain in terms of usability, accessibility, and the need for simplified interfaces to broaden adoption. Furthermore, the studies point to the potential of combining AR with AI to analyze consumer emotions and dynamically tailor experiences based on real-time emotional responses. This review concludes that although AR has the potential to revolutionize e-commerce, further research is needed to address the long-term impact of AR on consumer behavior, explore its adoption in diverse geographical contexts, and develop more intuitive and accessible AR solutions. Investigating the role of AI in emotion analysis and the personalization of AR experiences also presents a promising area for future research.

Knowledge Discovery from Urban Mobility Data in Guimarães

Urban mobility has been a challenge for policymakers in several cities, including Guimarães. This scenario is the result of population growth and the increasing number of vehicles per person, making it imperative to adapt urban planning to this expansion. This study aimed to examine urban mobility in Guimarães, considering factors such as the time of day, temperature and whether it is a working day. The results indicated that the flow of pedestrians is lower than that of cars, with considerable differences. The number of pedestrians and cars was also quite different under different conditions, such as seasonality, time of day, type of day and type of avenue. The final contribution of this study, based on the analysis of mobility on each avenue and its profiles, demonstrated not only the usefulness of the results for optimising the resources of municipal authorities, but also made it possible to identify the territorial conditions and characteristics that promote more sustainable mobility.

The Emotional and Empathic Dimension of Augmented Reality in E-Commerce: A Theoretical Framework for Purchase Intention

Augmented Reality (AR) is transforming e-commerce, offering immersive experiences that transcend the simple visualisation of products. However, understanding the impact of the emotional and empathetic dimensions created by such experiences on consumer purchase intent remains limited. This article proposes an innovative theoretical framework that integrates emotional constructs (valence and activation), perceived empathy (influenced by mirror mechanisms simulated in AR), user experience factors (interaction time, sensory salience, cognitive load) and perceived usefulness to model user engagement (UE) and, subsequently, purchase intention (PI) in AR-enriched e-commerce environments. The model is based on a review of recent literature (with the majority of articles between 2020-2025) on AR in e-commerce, the psychology of emotions, neurodesign and consumer behaviour, using open-access articles indexed in Scopus and Web of Science. We present specific mathematical functions to quantify EU and PI, the latter modelled using a logistic function. The proposed framework aims to offer a deeper understanding of how AR can be designed to evoke positive emotional and empathic responses, optimising engagement and enhancing the purchasing decision. The theoretical and practical implications for researchers and marketers are discussed, as well as directions for future empirical research to validate and refine the proposed model, contributing to the advancement of knowledge at the intersection of technology, psychology and marketing in the context of e-commerce.

Behaviour of Machine Learning algorithms in the classification of energy consumption in school buildings

Abstract The significance of energy efficiency in the development of smart cities cannot be overstated. It is essential to have a clear understanding of the current energy consumption (EC) patterns in both public and private buildings. One way to achieve this is by employing machine learning classification algorithms, which offer a broader perspective on the factors influencing EC. These algorithms can be applied to real data from databases, making them valuable tools for smart city applications. In this paper, our focus is specifically on the EC of public schools in a Portuguese city, as this plays a crucial role in designing a Smart City. By utilizing a comprehensive dataset on school EC, we thoroughly evaluate multiple ML algorithms. The objective is to identify the most effective algorithm for classifying average EC patterns. The outcomes of this study hold significant value for school administrators and facility managers. By leveraging the predictions generated from the selected algorithm, they can optimize energy usage and, consequently, reduce costs. The use of a comprehensive dataset ensures the reliability and accuracy of our evaluations of various ML algorithms for EC classification.

Data Platforms for Real-time Insights in Healthcare: Systematic Review

The ever-growing usage and popularity of Internet of Things devices, coupled with Big Data technologies and machine learning algorithms, have allowed for data engineers to explore new opportunities in healthcare and continuous care. Furthermore, there is a need to reduce the gap on time from when information is created to when actions and insights can be offered. However, a challenge in implementing a large-scale data processing architecture is deciding which tools are appropriate, and how to apply them in the best way possible. For example, streaming systems are now mature enough that hospitals worldwide can use their extremely large datasets, along with data producers, to predict and influence future events. Thus, the main objective of this systematic review is to identify the state-of-the-art in data platforms on healthcare that allow the creation of metrics and actions in real-time. The PRISMA guideline for reporting systematic reviews was implemented to deliver a transparent and consistent report, validating the technological advances in a critical sector. Multiple pertinent articles and papers were retrieved from the SCOPUS abstract and citation database on May 13, 2022, using several relevant keywords to identify potentially relevant documents published from January 2020 onward. These documents must have already been published in English and been already published, and accessible through the B-ON consortium that allows Portuguese students to legally download from most publishers. Over seven studies have been selected for deeper discussion based on their relevance and impact for this review, showcasing their main objectives, data sources, and tools used, as well as their approaches for interoperability and support of machine learning algorithms for decision support. In closing, the collected articles have shown that while Big Data is currently in use at health institutions of all sizes, the ability of processing large amounts of data from sensors and events, and notifying stakeholders as quickly as possible is still in its infancy.
