As an extension to the repertoire of WIMP techniques, Responsive Positioning facilitates the perception and manipulation of attributes of on-screen objects by perceiving and manipulating their positions in relation to a structured background. The technique is based on in-depth analyses of the technical potentials of interactive user interfaces and the role of space in knowledge work processes. As for both areas there are no theoretical frameworks on the basis of which a proper determination of the status quo let alone the systematic development of a new user interface technique would be possible, innovative approaches are developed and applied. Technical potentials of interactive user interfaces are determined by considering milestones in the history of the development of these interfaces. This approach allows both for a description of the state of the art, as well as for an analysis of unused potentials. Knowledge work processes are examined to what extent they use spatial properties as a means of determining properties about spatially arrangeable objects. A combination of both investigations shows that the commonly used knowledge work technique of structuring space and positioning objects in relation to it can be combined with certain potentials of digital interfaces, thereby building the foundation for a new user interface technique. This technique is subsequently developed and formally specified. Explanations of exemplary applications of the resulting Responsive Positioning technique serve the purpose of proving the feasibility of the approach while at the same time being the basis for an application architecture which allows the integration of the new technique into existing ...enText/Dissertation10.17619/UNIPB/1-280
