This article focuses on the design potential of digital interactions where the body is seen as the interface. With computational technology and sensors infiltrating many aspects of our lives and urban surroundings,interaction designers’ ability to visualise and generate designs are important in order to understand and explore such design spaces. I propose three concepts—accessibility, immediacy and generation—as means for analysing movement as a design material for interaction design. Drawing on a social semiotics approach, contemporary choreographic research is studied where digital tools are used to generate, explicate and communicate interactive movement. I argue that by drawing on the particularities and potentials of the moving body as interface such as those explored through choreographic practice, we may avoid imitating existing exchanges with technology and create novel interactions.
