To develop a 3D curve sketching interface that captures the natural affordances of pen and paper, enabling designers to iteratively build concept models directly in 3D space.
Integrated novel interaction techniques, including automatic view rotation for optimal curve sketchability, an axis widget for sketch surface selection, and implicit switching between sketching modes.
Implemented streamlined interaction features such as multi-stroke NURBS curve generation, simplified 2D and 3D navigation, a virtual sketchbook, and a unified gesture vocabulary.
Evaluated the usability and practical viability of the system through an assessment with a professional designer.
Facilitated seamless, direct generation and refinement of complex 3D curve networks using pen-based interactions.
User evaluation with a professional designer demonstrated that the system successfully supports core conceptual design tasks within real-world creative workflows.
