- SeniorBox: Co-creating a toolkit to develop games for older adultsPublication . Pereira, M.; Regalado, Francisco; Ferreira, Sónia; Veloso, Ana IsabelPopulation ageing has become one of the most significant demographic trends of the twenty-first century, posing major challenges to the promotion of active and healthy ageing. In Portugal, long-term care institutions face difficulties in providing meaningful activities that support older adults’ autonomy and wellbeing. In this context, games have emerged as a promising approach to reducing functional decline by fostering cognitive, physical, and social engagement. This study presents SeniorBox, a low-cost toolkit of games designed to promote active participation among older adults. The research followed an iterative DesignBased Research methodology, developed across four iterations. Initially, a literature review and semi-structured interviews with institutional professionals were conducted to identify design principles aligned with older adults’ preferences and institutional constraints. The findings highlighted the importance of simple mechanics and rules, familiar themes, and elements that stimulate cognitive and social interaction, as well as the need for affordable and accessible materials. Based on these insights, a set of games was developed using everyday, low-cost objects and tested with older adults from care institutions in the Aveiro district, Portugal. Observational data revealed high engagement levels, ease of use, and significant social interaction during gameplay. Subsequent iterations focused on the development and evaluation of low and high-fidelity versions of the toolkit, including instructional materials and a supporting website. Usability was assessed with professionals using the System Usability Scale, resulting in a score above 90%, indicating excellent usability. Overall, the study contributes a validated toolkit, practical design guidelines, and empirical evidence supporting the role of games in promoting autonomy and active ageing among older adults.
- Evaluating Digital Transformation in SMEs Through Value Creation, Strategic Management, and SustainabilityPublication . Gouveia, Sónia Maria Marques Teixeira Mendonça; Abrantes, José Luís; Gouveia, Eduardo; Iglesia, Daniel H. de la; Vaz, Maria; Rivero, Alfonso J. López; ANTUNES VAZ, PAULO JOAQUIMThis study proposes a multidimensional decision-support model for assessing the strategic implications of Digital Transformation (DT) in SMEs under conditions of uncertainty. The study addresses the challenge of measuring the digital impact of DT across value creation, strategic management maturity, and sustainability dimensions. A conceptual framework grounded in strategic management and digital transformation literature is operationalized using the Fuzzy TOPSIS method. A controlled stochastic simulation was conducted to generate a synthetic dataset representing 30 heterogeneous SMEs for computational model-validation purposes. The proposed framework generates three dimension-level performance indices and one aggregated Global Digital Impact Index (GDII). The simulation results illustrate the analytical potential of the framework to support multidimensional digital impact assessment under uncertainty. The study contributes a fuzzy-based evaluation framework capable of integrating value creation, strategic management maturity, and sustainability within a unified digital impact assessment model.
