Digital and Interactive Platforms as networking and data-sharing tool

The paper investigates the evolution of digital platforms as complex socio-technical ecosystems focused on data visualization, exploration, and the mediation of social and informational networ- ks. Adopting an interdisciplinary perspective, the study analyzes how platforms reshape the production, consumption, and circulation of digital content, as well as the management of social relationships. Through a critical reading of the transition from the participatory web to contempo- rary platform models, the paper highlights how platforms are not only technological infrastructures, but also cultural devices capable of shaping practices, transferring information, and ma- naging content. The research is based on a comparative analysis of case studies grouped into four categories: Low Impact, Accessibility and Inclusion, Data Exploration and Visualization, and Algorithms and AI. This analysis highlights recurring design models and opportunities, with particular attention to modes of information exploration, and characteristics related to sustainability and platform usage. Within this framework, the paper explores the role of co-design practices as a methodological approach for testing and validating platforms. By actively involving users, stakeholders, and communities in the phases of ideation, prototyping, and evaluation of UX and UI, co-design supports more responsive and inclusive design processes. Finally, the paper proposes a set of pre-design requirements and parameters for developing accessible, low-tech, and environmentally responsible platforms that promote economic sustainability and broaden access to digital content, fostering more inclusive and conscious digital ecosystems.
