Abstract

This paper summarizes elements of research on the effectiveness of using qualitative spatial representation (QSR) in 2D and 3D display modes to determine its usefulness for situational awareness and decision making. The study involved: 1) creating spatial query functions based on QSR that capture knowledge about objects in space; 2) building these query functions into a graphical user interface environment as simulated user accessible support functions; and 3) testing the utility of these support functions by evaluating the performance of human subjects in solving sets of spatial decision-making and information retrieval tasks.
