It introduces a typology of five care-politics, a framework for understanding how care is put into practice. Using case studies that range from a workshop on gender in design to the ongoing responsibilities of research devices, the book explores the pitfalls of working ‘with care’ and proposes more inventive approaches to ethics.This is a key resource for scholars and students grappling with the ethical and political dimensions of design and related fields.
