This dissertation is about the research program designing with care as a pathway towards interaction design otherwise amid a world in crisis. Considering how established ways of doing interaction design will change involves recognizing the role of digital materials in social injustice and systemic inequality. These concerns are inseparable from the material complexity of interactive experiences and their more-than-human entanglements in care. Through five design experiments, I explore everyday human care as wickedly attending to some care doings and not others, and an intimate and generous questioning of oneself as human.

I offer four contributions for interaction designers and design researchers. The first contribution is designing with care. This research program draws upon care ethics and posthumanism to establish four axioms: everyday, wickedness, intimacy, and generosity. Within this programmatic framework, the second contribution is definitions of wickedness and generosity as ethical stances that can be taken by designers and researchers. The third contribution is the synthesis of my four methodological approaches: auto-design, spatial orientations, leaky materials, and open speculations. Each is a generative and analytical pathway towards more sustainable and just futures. The fourth contribution is five careful designs as prototypes of what interaction design otherwise might be like: technologies of human waste, spying on loved ones, leaky breastfeeding bodies, scaling bodily fluids, and a speculative ethics. 

From my research program and contributions, I discuss disciplinary resistances to suggest three possibilities for how I argue interaction design should change: engaging with mundane yet unrecognized topics, doing design work where the consequences would be present, and reconsidering how the formats of research publications could better reflect positionality. I then reflect upon the relevancy of self-centered research in moving beyond oneself for more sustainable worlds.
