In this reflective stage of my research I did find it necessary to do one last experiment which became a kind of container of all previous experiments while focusing the work on the scientific contribution. In this last ‘test’ the scientific contribution finally became clear: a technique of digital modeling – from the point of (digital) material properties so that the digital design object could provide feedback to influence the design because its material properties were able to connect to spatial influences, in other words the digital object being designed was not neutral but had agency due to its material and spatial interactions and these were communicated in an intuitive, (almost*) haptic interface. *the Sensor Models are still quite buggy and so this haptic interface is not smooth while still able to provide some sense of the object.
