Data-driven technologies increasingly participate in everyday experiences as implicit interactions that are unseen and dynamically configured. My research explores the design and implications of implicit interactions by designing within social relations of care that are often considered taboo. These include caring for loved ones and technologies to manage human excretion: situations that are difficult to quantify and where an unintended consequence of implicit interactions can be devastating. To carefully challenge definitions of implicit interactions, I draw upon autobiographic and speculative design methods, as well as humor to unsettle others and implicate myself in care.
