Summary:
This paper describes the creation of the nuSketch COA diagramming application. My PowerPoint presentation describes the history of military symbology, the evolution of Course of Action diagrams, and gives an overview of nuSketch itself (screen shot below).

nuSketch, “…is designed to be an interface to battlespace reasoning systems, built both by us and by others. Spatial reasoning is a crucial component in most battlespace reasoners. Consequently, we incorporate a suite of visual computations in nSB that use sketched input to provide a combination of domain-specific and domain-independent qualitative spatial reasoning.”

This paper, in turn, introduces the important topic of qualitative spatial reasoning (see below).
