This article proposes a critical inquiry of interactive environments as fields of transduction. It is argued that Gilbert Simondon’s concepts of individuation, transduction, in-formation, the preindividual, and the associated milieu enable a processual thinking of the analysis and design of interactive technologies as technogenetic emergence. These concepts offer a way for interaction design to understand interactive environments through the dynamics between fields of transduction and fields of experience in relational and affective terms. The article analyses the way in which two technological assemblages, Voz Alta and the Impossible Room, provide different experiential fields experimenting with the transductive power of digital and interactive media. We emphasise the potential for creating new modes of experience. Our aim is to underline the necessary convergences between practices of design and thought; to enable affectively engaging fields of transduction.
