Through my practice I explore the potential for open interactive installations in digitally mediated public spaces, often using urban screens. I have developed a number of mixed reality artworks to prompt play and interaction across social and cultural boundaries. My interactive installations provide a framework with an environment that offers a visual context for interaction, engagement and play on an international stage. I examine audience agency and opportunities for play, testing the boundaries of open systems, to offer opportunity for diverse audiences to co-create artworks through the development of unique narratives. Through my research I test the potential for interactive environments on urban screens to promote public participation through shared experience, impacting on culture, health and wellbeing, changing the way we engage in the urban environment and public space and contributing to a collective memory of place in a global context.
