In this contribution we present a cognitively motivated approach to an interactive assistance system for spatio-temporal planning tasks. Since mental spatial problem solving is known to be based on hierarchical representations, we argue for region-based representation structures that allow for structuring a complex spatio-temporal problem such that exploring and communicating alternative soluti...

This paper describes Music Haptic, an application which enables users (especially blind users) to train of musical harmony notions due to a spatial representation and a force feedback mouse. This mouse enables the progressive rebuilding of the mental image of a graphical document through knowing the positions of its elements. We present technical context of our prototype and the possible altern...

‎We study the spatial distribution of point sets on the sphere obtained from the representation of a large integer as a sum of three integer squares‎. ‎We examine several statistics of these point sets‎, ‎such as the electrostatic potential‎, ‎Ripley's function‎, ‎the variance of the number of points in random spherical caps‎, ‎and the covering radius‎. ‎Some of the results are conditional on t...

In the domain of numbers the existence of spatial components in the representation of numerical magnitude has been convincingly demonstrated by an association between number magnitude and response preference with faster left- than right-hand responses for small numbers and faster right- than left-hand responses for large numbers (Dehaene, S., Bossini, S., & Giraux, P. (1993) The mental represen...
