Abstract

Marine plastic and microplastic pollution can be difficult to communicate because its impacts unfold slowly, are geographically dispersed, and often remain imperceptible. We address this challenge through In Deep Water, a public-facing interactive installation that translates marine science research into collaborative exploration. The system combines a sculpted virtual marine biorama with custom-built physical controllers that allow players to navigate simulated waterways, locate discarded research beacons, and decode situated data from studies conducted in Aotearoa, New Zealand. The installation is developed in two complementary modes, one designed for open-ended exploration and the other structured around time-limited play, to investigate how different interaction conditions shape engagement and sense-making. Our contribution is a replicable design approach for turning environmental datasets into embodied, social experiences, supporting HCI researchers and practitioners designing data-driven public installations and educators and cultural institutions seeking accessible formats for research translation and environmental engagement.
