    Movement Choremes: Bridging Cognitive Understanding and Formal Characterizations of Movement Patterns1.Alexander Klippel - 2011 - Topics in Cognitive Science 3 (4):722-740.
    This article discusses an approach to characterizing movement patterns (paths/trajectories) of individual agents that allows for relating aspects of cognitive conceptualization of movement patterns with formal spatial characterizations. To this end, we adopt a perspective of characterizing movement patterns on the basis of perceptual and conceptual invariants that we term movement choremes (MCs). MCs are formally grounded by behaviorally validating qualitative spatio-temporal calculi. Relating perceptual and cognitive aspects of space and formal theories of spatial information has shown promise to foster (...)

    Spatial Symbol Systems and Spatial Cognition: A Computer Science Perspective on Perception-Based Symbol Processing.Christian Freksa, Thomas Barkowsky & Alexander Klippel - 1999 - Behavioral and Brain Sciences 22 (4):616-617.
    People often solve spatially presented cognitive problems more easily than their nonspatial counterparts. We explain this phenomenon by characterizing space as an inter-modality that provides common structure to different specific perceptual modalities. The usefulness of spatial structure for knowledge processing on different levels of granularity and for interaction between internal and external processes is described. Map representations are discussed as examples in which the usefulness of spatially organized symbols is particularly evident. External representations and processes can enhance internal representations and (...)

    Intuitive Direction Concepts.Alexander Klippel, Jan Oliver Wallgrün, Jinlong Yang & Kevin Sparks - 2015 - Baltic International Yearbook of Cognition, Logic and Communication 10 (1).
    Experiments in this article test the hypothesis that formal direction models used in artificial intelligence correspond to intuitive direction concepts of humans. Cognitively adequate formal models of spatial relations are important for information retrieval tasks, cognitive robotics, and multiple spatial reasoning applications. We detail two experiments using two objects systematically located in relation to each other. Participants performed a grouping task to make their intuitive direction concepts explicit. The results reveal an important, so far insufficiently discussed aspect of cognitive direction (...)
