Co-creation, as a principle, challenges the assumptions concerning creativity and authority as inherent in the individual, predominantly the male individual. Co-creation recognises that both authority and creativity are socially constituted and maintained, thus altering the characteristics and roles of the designer. Co-creation is particularly relevant for the design of narrative environments, as it produces new and dynamic ways to connect the people node to the narrative and environment nodes in the tripartite network. Collaboration among professional designers comes about for many reasons. In order to explore participatory practices in narrative environments, it is worth reflecting on participatory art practice which, since the 1960s, has blurred the distinction between art production and consumption, on the one hand, and art and life, on the other. Socially-engaged participatory narrative environments have embraced the principles of co-design and subscribe to the inclusion of multiple, diverse voices and user-generated content.
