Introduction
Shape design using intuitive 3D interaction techniques for free-form modeling increases
its contribution to...
through product differentiation
André Stork
The Eraser Pen: A New Interaction Paradigm for Curve Sketching in 3D
Current Practice and Obstacles
Can not handle quick sketching concepts.
Serious difficulties are encountered in the styling
phase of the design process
As a result, designers prefer to use manual
sketching tools

Current use of VR and AR within the Design Process
Virtual Validation Process
