Towards a Computational Model of Sketching

Abstract

Sketching is a powerful means of communication between people. While many useful multimodal systems of communication have been created, current systems are far from achieving human-like participation in sketching. A computational model of sketching would help characterize these differences and help people better understand how to overcome them. This paper is a first step towards such a model. The authors start with an example of a sketching system (nuSketch COA Creator) designed to aid military planners to provide context and a source of examples. They then describe four dimensions of sketching -- visual understanding, conceptual understanding, language understanding, and drawing -- that can be used to characterize the competence of existing systems and identify open problems. Three research challenges are posed to serve as milestones towards a computational model of sketching that can explain and replicate human abilities in this area.
