Digital Silver Hub: User Dialogue Model Technical Document

A phenomenal change in the age pyramid of the European Union countries has been depicted, where a significant increase in the retired age citizens and a decrease in the percentage of working-age citizens is expected. Therefore, the European Union along with the Baltic Sea Region actively participate in research on active ageing and technology-driven services to enable the elderly to live an independent life. One such EU-funded initiative is the OSIRIS project which undertakes the development of a collaborative platform named the ‘Digital Silver Hub’; an ecosystem aimed to provide innovative technological solutions to the challenges faced by the elderly population. The platform aims to enable the quadruple helix actors (private sector, public sector, academic institutions, and senior citizens) to participate in knowledge exchange, collaboration and co-creation to boost technological innovations that accommodate the needs and preferences of the elderly. In this document, the system user dialogue model has been documented outlining the user interface components of the Digital Silver Hub combining the proven frameworks of Human-Computer Interaction Pattern language by Christopher Alexander et al., Design Patterns by Erich Gamma et al. and Interaction Design Pattern by Jenifer Tidwell et al. Unified Modeling Language (UML) has been used to provide a visual representation of the constituents of the platform and how it leverages collective intelligence for the needs of the silver economy.
