A VR-based system for the virtual prototyping of shoes employs a user interface that mimics shoe designer's conventional work style, using a pen and a shoe last as 3D proxy objects. Users sketch design lines onto the last. For this task, the system employs an algorithm for real-time sketch recognition on curved surfaces. On the basis of the framework of curves, the system creates further design elements (for example, leather pieces) to complete the model. Users can employ three pen-based interaction metaphors to interact directly with design elements, to input values, or to make choices from a menu. A user study shows that conventional designers can easily learn and apply these interaction methods.
