This work has resulted in a framework for qualitatively representing and reasoning about spatial configurations in the two-dimensional case. The framework contains interval/region based formalisms for describing distances, angles, and locations. These representations lead to the formulation of spatial inference rules, as well as search heuristics which enable the prediction of spatial relationships and paths among objects. These have direct relevance to, and implications for, computer-aided mechanism design and robotics.
