The Eraser Pen: A New Interaction Paradigm for Curve Sketching in 3D
In this paper we present a new interaction technique for curve sketching in 3D which integrates the two tasks of creating and editing into one paradigm: the 3D-eraser pen. The eraser pen allows drawing and deleting curves in 3D without mode switching just by changing the direction of the hand movement. In that way we have combined the creation and deletion process, rewriting the pencil and rubber metaphor in just one tool. The aim is to support the user to create the intended shape from the beginning.As a proof-of-concept we have developed our concept in a semi-immersive virtual environment for 3D-curve sketching in free space.
