Access to reproductive care, shaped by legal, socio-economic, political, and identity-based factors, is unevenly distributed and increasingly precarious. This one-day workshop builds on previous CSCW workshops to address the pressing need to confront issues at the intersection of Human-Computer Interaction (HCI), design research, and reproductive justice in the face of global conservatism and escalating challenges to human rights. Through speculative design, the workshop invites researchers and practitioners to address challenges in this design space, such as, but not limited to, information distribution, privacy issues, identity-based barriers, and design for care. By pulling on the threads of designed artifacts central to reproductive care and ideating on novel designs and anti-designs, participants will collaborate to formulate design and design research's role in reproductive justice futures. The workshop aims to produce provocative ideas around the messy realities of reproductive justice. We contribute critical discussions and reflections on HCI's role in promoting change and combating the oppressive forces that affect reproductive justice.
