This paper presents an analysis of the presence and potential of a postphenomenology as a research method in human-computer interaction (HCI). Specifically, we introduce Rosenberger's method of variational cross-examination; an empirical approach that explores technological mediation through a critical comparison of multiple stabilities of a given technological artifact. With this outset, we revisit and analyze two existing HCI projects, a shape-changing bench and digitized sticky notes, and illustrate how a postphenomenological perspective may supplement these projects. Based on this analysis, we highlight the strengths and benefits of a postphenomenological approach to HCI research. Finally, we propose strategies for applying such an approach in future research.
