Design fiction is a type of speculative design, where story worlds are crafted to then be used as a canvas upon which so-called diegetic prototypes can be sketched [9]. Because these prototypes exist only within story worlds they are not constrained by currently available technology; because of this design fictions are excellent means to open up space for critical conversations about the future [2,6]. This project experiments with using design fiction as a novel way to explore the complexities of technology and ethics. We focus on one specific case to demonstrate the method we adopted, however the contribution is general in nature and may be applicable to other cases too. The work consists of two parts, this paper and a ‘design fiction documentary’ film, ‘Care for a Robot’. The paper and film are intended to be viewed together.
