The paper "Research through Design as a Method for Interaction Design Research in HCI" by John Zimmerman, Jodi Forlizzi, and Shelley Evenson explores the integration of design in HCI research and practice. The authors propose a new model for interaction design research within HCI, emphasizing the production of artifacts that transform the world from its current state to a preferred state. This approach allows interaction designers to make significant research contributions by addressing under-constrained problems. The model is formalized with four lenses for evaluating research contributions and three examples illustrating its benefits. The paper highlights the importance of design in HCI, particularly in tackling "wicked problems," and provides a framework for interaction designers to engage effectively in HCI research. The authors also discuss the challenges and opportunities in integrating design into HCI, emphasizing the need for a unified vision and clear criteria for evaluating design research contributions.The paper "Research through Design as a Method for Interaction Design Research in HCI" by John Zimmerman, Jodi Forlizzi, and Shelley Evenson explores the integration of design in HCI research and practice.
