In this paper we recount several research projects conducted at ImaginationLancaster a Design-led research laboratory, all of which consider Object-Oriented Ontology. The role OOO plays in these projects is varied: as a generative mechanism contributing to ideation; as a framework for analysis; and as a constituent in developing new design theory. Each project’s focus is quite unique—an app, a board game, a set of Tarot cards, a kettle and a living room—however they are all concerned with developing new understandings relating (...) to the ubiquitous, networked, ‘smart’ technologies which are often referred to as the Internet of Things. Through our reflexive account of these research projects the aim of this paper is to provide insights into, and promote new discussion about, the relevance and scope for OOO in socio-technical Design Research, and beyond.
