In this paper, I build on perspectives in HumanComputer Interaction (HCI) and design literature to develop a theoretical lens to conduct personal inventories of human-product relationships within the home. I describe an ongoing empirical study examining participants' attitudes toward and relationships with interactive technology, and frame this research within the nascent and growing literature in HCI on environmental sustainability. I will present early findings from this study and discuss how these implications can inform potential future design practice within the HCI community.
