The goal for this workshop is to further experiment with a venue at CHI for practitioners of research through design to share their work with each other. This workshop, following a successful workshop in CHI 2016, will be centered upon a discussion of objects produced through a research through design process. Bringing together researchers as well as their physical work serves to gain insight into the practices and outcomes of research through design. If research through design is to continue to develop as a research practice for generating knowledge within HCI, this requires developing ways of attending to its made-material outcomes. The premise of this workshop is simple: We need additional social spaces and platforms for interacting with and reflecting upon material design outcomes at CHI. The goal of this workshop is to keep experimenting with such a space, with an emphasis on how prototyping and making in a research through design context produces design things.
