    Linked Data Generation Methodology and the Geospatial Cross-Sectional Buildings Energy Benchmarking Use Case
    (MDPI, 2024) Martínez-Sarmiento, Edgar A.; Broto, José Manuel; Gabaldon Ponsa, Eloi; Cipriano, Jordi; García González, Roberto; Danov, Stoyan
    Cross-sectional energy benchmarking in the building domain has become crucial for policymakers, energy managers and property owners as they can compare an immovable property performance against its closest peers. For this, Key Performance Indicators (KPIs) are formulated, often relying on multiple and heterogeneous data sources which, combined, can be used to set benchmarks following normalization criteria. Geographically delimited parameters are important among these criteria because they enclose entities sharing key common characteristics the geometrical boundaries represent. Linking georeferenced heterogeneous data is not trivial, for it requires geographical aggregation, which is often taken for granted or hidden within a pre-processing activity in most energy benchmarking studies. In this article, a novel approach for Linked Data (LD) generation is presented as a methodological solution for data integration together with its application in the energy benchmarking use case. The methodology consists of eight phases that follow the best principles and recommend standards including the well-known GeoSPARQL Open Geospatial Consortium (OGC) for leveraging the geographical aggregation. Its feasibility is demonstrated by the integrated exploitation of INSPIRE-formatted cadastral data and the Buildings Performance Certifications (BPCs) available for the Catalonia region in Spain. The outcomes of this research support the adoption of the proposed methodology and provide the means for generating cross-sectional building energy benchmarking histograms from any-scale geographical aggregations on the fly.

    Towards a Refined Heuristic Evaluation: Incorporating Hierarchical Analysis for Weighted Usability Assessment
    (MDPI, 2024) Talero-Sarmiento, Leonardo; González Capdevila, Marc; Granollers i Saltiveri, Toni; Lamos-Diaz, Henry; Pistili-Rodrigues, Karine
    This study explores the implementation of the analytic hierarchy process in usability evaluations, specifically focusing on user interface assessment during software development phases. Addressing the challenge of diverse and unstandardized evaluation methodologies, our research develops and applies a tailored algorithm that simplifies heuristic prioritization. This novel method combines the analytic hierarchy process framework with a bespoke algorithm that leverages transitive properties for efficient pairwise comparisons, significantly reducing the evaluative workload. The algorithm is designed to facilitate the estimation of heuristic relevance regardless of the number of items per heuristic or the item scale, thereby streamlining the evaluation process. Rigorous simulation testing of this tailored algorithm is complemented by its empirical application, where seven usability experts evaluate a web interface. This practical implementation demonstrates our method’s ability to decrease the necessary comparisons and simplify the complexity and workload associated with the traditional prioritization process. Additionally, it improves the accuracy and relevance of the user interface usability heuristic testing results. By prioritizing heuristics based on their importance as determined by the Usability Testing Leader—rather than merely depending on the number of items, scale, or heuristics—our approach ensures that evaluations focus on the most critical usability aspects from the start. The findings from this study highlight the importance of expert-driven evaluations for gaining a thorough understanding of heuristic UI assessment, offering a wider perspective than user-perception-based methods like the questionnaire approach. Our research contributes to advancing UI evaluation methodologies, offering an organized and effective framework for future usability testing endeavors.

    Gender literacy through the making process: A feminist pedagogy approach
    (Elsevier, 2024-03-08) Schaper, Marie-Monique
    This article aims at exploring how to support students' awareness on gender stereotypes and the development of gender literacy through the making process of interactive toys. I present a case study with 22 primary students (11-12 years) from a public primary school in Barcelona (Spain) who were involved in a maker workshop series. Building on principles of transformative feminist pedagogy, the article shows exemplary design activities for children to create a space for dialogue and reflection upon gender stereotypes. To this end, the activities were used as a means to spark critical reflections among the students and to guide them in the design of prototypes of cross-gendered interactive toys. By analyzing students' artifacts and verbal expressions during the discussions, the study illustrates how they gradually discovered their own assumptions on gender stereotypes and were enabled to propose cross-gendered alternatives for interactive toys focusing on movement-based and collaborative activities. Finally, the article presents a set of educational activities that support students to reflect upon gender stereotypes in the making process and guidelines for teachers to integrate these strategies into their educational practices.

    Onboarding new talent to Child-Computer Interaction research: Teaching a tasting menu of CCI as an elective research subject
    (Elsevier, 2024-04-09) Schaper, Marie-Monique; Tamashiro, Mariana Aki; van Mechelen, Maarten; Iversen, Ole Sejer; Eriksson, Eva
    We present a case study in which we seek to investigate what motivates interaction design students to take a small elective course in Child-Computer Interaction (CCI) and what we can offer as a 'tasting menu', a small sample of emerging research specialties, to awaken their interest for CCI. The study clarifies what motivated students to take the elective course and what their learning expectations were before the start of the course. We then prototyped and piloted a research-based 'tasting menu' type of course and conducted a formative and summative evaluation with the students. The contribution of this paper is a set of recommendations for onboarding new talent to the research field by teaching CCI in a modular fashion to interaction design students, based on students' and teachers' experiences.

    Enhancing active aging through IRAGE: Mitigating social isolation with intergenerational gaming
    (Elsevier, 2024) Díaz Llobet, Manel; Gil Iranzo, Rosa María; Cabeza, Luisa F.; Cerezo, Eva; Teixidó Cairol, Mercè
    This paper presents the outcomes of a pioneering study that explores the potential of remote intergenerational communication to combat social isolation among children and older adults, especially under constraints posed by pandemics such as COVID-19. Acknowledging the limited mobility of many older adults, this research aims to provide insights into how digital platforms can facilitate meaningful exchanges between generations. Utilizing a mixed methodology approach, the study first conducted a user interaction analysis to outline guidelines for participant engagement with the Information and Communication Technology (ICT)-based tool called IRAGE (Intergenerational Remote Access to Gaming Experiences) designed specifically for this purpose. Following the development of the ICT tool, three sessions of the remote intergenerational experience were held, during which participants' interactions were recorded and subsequently analyzed quantitatively and qualitatively. Key findings from the study reveal that remote intergenerational communication can significantly mitigate feelings of isolation among older adults, contributing to their mental health and emotional well-being. Moreover, the study highlights the effectiveness of the web-based platform in facilitating these interactions, with older adults and children finding the user interface intuitive and the overall experience engaging. These outcomes underscore the importance of leveraging technology to maintain social connections during challenging times and offer valuable guidelines for developing ICT tools that cater to the needs of diverse user groups. By demonstrating the feasibility and benefits of remote intergenerational communication, this research contributes to the broader discourse on active aging and the role of digital technologies in promoting social inclusion and emotional health.
