Abstract

Diagrams used in many domains often require continual redrawing. Diagram drawing programs often aid redrawing by applying secondary corrections that change visual elements to maintain preexisting relationships. These corrections, though useful, can operate in unintuitive ways and cause disfluencies. We describe an implemented prototype system that improves corrections based on place vocabularies (domain-specific spatial relation sets). Place vocabulary constraints (PVCs) translate high-level place vocabularies into low-level geometric constraints by reversing pre-existing recognition rules. By making corrections congruent with a domain vocabulary, PVCs may provide more intuitive drawing corrections.
