Interactive Layout Generation with a Diagrammatic Constraint Languagepressed in a formal language and a set of unformalized mental constraints, e.g. esthetic preferences. For this type of problem, the performance of a layout assistance system does not only depend on its use of computational resources (algorithmic complexity) but also on the mental effort required to

Inference and Visualization of Spatial Relationsdo not use discrete symbolic models. Instead, relations between pairs of objects are represented by parameterized homogeneous transformation matrices with numerical constraints. A textual description of a spatial scene is transformed into a graph with objects and annotated local reference systems as

A Topological Calculus for Cartographic Entitiespological relations for which two approaches can be found in the literature: region-based approaches, for which the basic spatial entity is the spatial region; and point-set approaches, for which spatial regions are viewed as sets of points. We will follow the latter approach and provide a calculus

The Influence of Linear Shapes on Solving Interval-Based Configuration Problemsell-established mental model theory of human reasoning. Since it is a well-known fact that content and context affects human inference, we are interested to know to what extent abstract properties of linear shape curves conform to previous findings of interval-based reasoning. This investigation is

Transfer of Spatial Knowledge from Virtual to Real Environmentsomain have revealed that the properties of spatial representations are globally the same in virtual and real environments, and in most cases transfer of spatial information from one kind of environment to the other occurs. Although these results suggest that virtual environments contain much of the

Schematic Maps for Robot Navigationbal spatial information are noted. Different types of spatial representations for spatial knowledge are contrasted. The advantages of high-level / low-resolution knowledge are pointed out. Creation and use of schematic maps are discussed. A navigation example is presented.

Interactive Layout Generation with a Diagrammatic Constraint Languagely constrained rectangle layout task and propose a measure for the cognitive complexity. It is discussed how the user’s control of the presentation order of the different constraint instantiations affects the cognitive complexity.

Inference and Visualization of Spatial Relations consisting of equations and inequations containing trigonometric functions can be solved using machine learning techniques. By assigning values to the parameters and using heuristics for the placement of objects, a visualization of the described spatial layout can be generated from the graph.
