This paper proposes a new model for interaction design research within Human-Computer Interaction (HCI) that emphasizes research through design. The model allows interaction designers to contribute to HCI research by addressing under-constrained problems and creating artifacts that transform the world from its current state to a preferred state. The model is based on Frayling's research through design approach and highlights the role of design artifacts as outcomes that can influence both the research and practice communities. The paper provides four lenses for evaluating the quality of an interaction design research contribution: process, invention, relevance, and extensibility. It also includes three examples of interaction design research that illustrate the benefits of this approach. The first example is Xerox's work on reprographics machines, which demonstrated an integration of cognitive research and provided a design language that is still relevant today. The second example is Philips' Vision of the Future project, which explored possibilities for life and technology in the near future and provided a preferred state for future design. The third example is Apple's Guides project, which used theory from cognitive psychology to address the issue of people getting lost in hypertext interfaces. The paper concludes that this model allows interaction designers to collaborate with HCI researchers and provides a new method for transferring knowledge from research to practice. The model also encourages the HCI community to discuss preferred states and reflect on the potential impacts of research on the world.This paper proposes a new model for interaction design research within Human-Computer Interaction (HCI) that emphasizes research through design.
