Biomaterial Playground: Engaging with Bio-based Materiality

Recently, HCI researchers have shown interest in sustainability in the context of both new making methodologies and materials. In this work, we introduce a range of sustainable biomaterials (materials that are bio-based) that we use to create unique interactive interfaces. These biomaterials include ReClaym, a clay-like material made from compost; Alganyl, an algae-based bioplastic; Dinoflagellates, bioluminescent algae; SCOBY, symbiotic cultures of bacteria and yeast; and Spirulina, nutrient-dense blue-green algae. We describe how the implementation of these materials in our designs highlight the importance of utilizing materials that can biodegrade. We also call attention to the importance of care, patience, and understanding during the design processes to facilitate the creation of playful designs that respect the agency of each biomaterial. Lastly, we discuss the gained deeper sense of intimacy and understanding with our biomaterials which not only lead to more personally meaningful interfaces but more sustainable ones.
