A conceptual modeling approach actualizing the pencil and paper metaphor

Published: 04 June 2007 Publication History

Abstract

This article presents a system for sketching on pen-based displays to create conceptual engineering designs. The system incorporates recognition of command gestures, stroke preprocessing, segmentation, classification, and approximation, furthermore regularization and snapping, embedding and post-processing.
Particular attention has been paid to the usability of the system. To achieve our goal, we first analyzed the design process and the role of pencil and paper sketching.
Unlike other systems, our system has been designed for permanent revision of the input, including erasing and crossing out incorrect details. The system tries to strike a balance between the creative freedom of pencil and paper sketching and the advantages of digital data processing.
