The document describes a workshop that aims to teach participants how to design speculative lifeworlds instead of just artifacts. The workshop introduces techniques to envision fictional worlds where speculative artifacts could exist and function by defining the necessary social, economic, political and technological conditions. Participants will first build the characteristics of an imagined world and then write short stories set in that world. The goal is to provide a more systemic approach to speculative design that focuses on designing the broader contexts around fictional objects, not just the objects themselves.
