A sustainable practice method of hand-drawing by merging user's stroke and model's stroke

Nowadays, people have become able to publish their comics easily because of the spread of Web services featuring their own content. However, it is not easy for them to publish such comics because of the difficulty of improving their hand-drawing skill. One practice method is tracing. However, it is not easy for people to maintain motivation for this practice method. In this paper, we propose a method which enables people to improve their hand-drawing skills and motivation by creating a merging of their hand-drawn character and a corresponding model which is drawn by others automatically. We validate the usefulness of our method by using the system and show how to change the appearance of illustrations.
