Abstract: We describe the technology and diverse applications of a novel approach for transforming both pre-existing and purpose-designed physical artefacts into contact-sensitive interfaces and installations. Our approach builds upon attaching or embedding a six degree-of-freedom (6-DOF) force-torque sensor into a physical artefact. By this, artefacts can be transformed into active, computationally mediated interfaces for users to engage with associated digital media such as sounds, images, videos and graphics. We are able to sense the position of physical forces; the orientation and magnitude of these forces; and inductively, the presence, number and entrance/exit of multiple physical entities within such interfaces. Our approach is applicable across a number of materials and use contexts, ranging from millennia-old stone sculptures, to three-dimensional printed medical artefacts, to many-object game boards and well beyond. This paper focuses on the technical implementation, design criteria and limitations of the approach, illustrates example for uses and suggests promising domains for future applications.
