Design research and practice within HCI is inherently oriented toward the future. However, the vision of the future described by HCI researchers and practitioners is typically utility-driven and focuses on the short term. It rarely acknowledges the potentially complex social and psychological long-term consequences of the technology artefacts produced. Thus, it has the potential to unintentionally cause real harm. Drawing on scholarship that investigates the link between fiction and design, this workshop will explore "alternate endings" to contemporary HCI papers. Attendees will use fictional narratives to envision long-term consequences of contemporary HCI projects, as a means for engaging the CHI community in a consideration of the values and implications of interactive technology.
