Tahuti: A Geometrical Sketch Recognition System for UML Class Diagrams

Tracy Hammond and Randall Davis

We have created and tested Tahuti, a dual-view sketch recognition environment. The system is based on a multi-layer recognition framework which recognizes multi-stroke objects by their geometrical properties allowing users the freedom to draw naturally as they would on paper rather than requiring the user to draw the objects in a pre-defined msnner. Users can draw and edit while viewing either their original strokes or the interpreted veal!on of their strokes engendering user-autonomy in sketching.
