This chapter introduces Areca, which is designed to explore intimate and equivalent relationships. It is an IoT air purifier designed as a research artifact that writes diary entries to express its surroundings, thoughts, and feelings. Building on earlier observations that participants responded strongly to a thing’s perceived independence, the chapter asks whether a thing can be designed to feel both intimate in relational distance and equivalent in relational hierarchy, and how such relationships are formed through everyday interaction. Grounded in material speculation and extended through co-speculation, the project integrates a fine-tuned large language model with environmental sensing, embedded display, light, and plant-like movement to sustain Areca’s presence as a seemingly conscious being while remaining legible as a familiar appliance. Over a 3-week deployment with eight participants in homes, offices, dorms, and a lab, the study traces how diary writing and irregular, self-timed behavior shifted how participants interpreted and related to the thing. Participants reported a sensed presence, attributed agency to unpredictability and private self-narration, and negotiated tensions between functionality and subjectivity. They attempted to interpret Areca’s inner world, empathized when its diary resonated with their own experiences, and at times felt an emotional burden that complicated use. Relationships deepened through shared time and space, and through the ongoing work of getting to know Areca as a narrative-bearing presence that could still withhold itself. The chapter closes by reflecting on how perceived consciousness can reconfigure human-thing relations toward co-inhabitation, collaborative effort, and ethically charged emotional exchange while also introducing the frictions that arise when a tool no longer feels like a tool.
