Research through Design (RtD), a research approach that employs methods and approaches from design as a mode of inquiry, has gained momentum within HCI. However, the approach is not yet formalised, and there are ongoing debates about fundamental issues, such as how to articulate and evaluate knowledge that springs from RtD, and how this knowledge is comparable to knowledge from other forms of research. I propose that Rheinberger's conceptualisation of experimental systems, originally developed in the domain of the natural sciences, offers insights that can add to the understanding of these issues, and in turn to the development of RtD as a research approach. I examine key characteristics of experimental systems as they pertain to RtD, with a focus on the role of designs and forms of knowledge representation. I furthermore propose that the experimental systems perspective can shed light on similarities and differences between RtD and other research approaches.
