An intergenerational design research project that brings virtual reality and video gaming technologies to local communities in public housing as design communication tools. During a series of interactive and engaging co-design activities, youth and older adults are taken as co-researchers to critically reflect on public spaces and give agency to everyday knowledge. Participants are empowered with techniques of digital tools that help them to generate shared expressions of spatial needs and develop a mutual understanding of community interests. The participatory tools and processes are evaluated and published as open-source educational materials, together with the analysed co-design outcome.
