Abstract

This paper investigates the applicability of context-free grammars to recognize and interpret representative 3D freehand sketches in terms of creating objects, performing transformations, and controlling the design space with the information contained by the sketches. Dynamic gesture recognition is the foundation of a two-layered concept. The subsequent layer performs multiple gesture recognition by parsing a sequence of single gestures depending on a predefined grammar, and simultaneously extracts the required information on the fly.
