The immersive nature of Interactive Digital Narratives (IDNs) makes them a powerful platform for exploring underrepresented experiences. IDNs can reproduce or ‘simulate’ characteristics of a different point of view (POV), thereby immersing the interactor in the perspective of another. This approach has the potential to encourage deeper engagement with underrepresented or marginalized experiences but may also create unintended divides between the interactor and the represented group. In this analysis, I discuss the use of simulation in an IDN I recently created, One Art, which tells the story of a character living with aphasia, a language disorder. After analyzing the background, applications, and merits of simulation, I propose a methodology for revising my work, which includes co-designing with members of the affected community. This proposal draws on human-centered design and other participatory making methods.
