The aim of this one-day workshop is to share existing research, discuss common practices, and to develop new strategies and tools for designing for social justice in HCI. This workshop will bring together a set of HCI scholars, designers, and community members to discuss social justice perspectives on interaction design and technology. We will explore theoretical and methodological approaches in and around HCI that can help us generatively consider issues of power, privilege, and access in their complexity. We will discuss the challenges associated with taking a justice approach in HCI, looking toward existing practices we find both productive and problematic. This workshop will bridge current gaps in research and practice by developing concrete strategies for both designing and evaluating social change oriented work in HCI, where agendas are made clear and researchers are held accountable for the outcomes of their work by members of their field site and the research community.
