Towards Bimanual Control for Virtual Sculpting

Abstract

In 3D modeling, the work piece should be at the very center of attention. Many 3D modeling tools work rather directly on the mathematical representations, such as polygonal meshes. In contrast, virtual sculpting abstracts the 3D modeling process by providing virtual tools not unlike those used by artists for sculpting physical objects. In this paper, we investigate how virtual sculpting can benefit from bimanual interaction on interactive surfaces. We present our interface design and the results of a con-ducted case study comparing bimanual interaction on interactive surfaces to bimanual interaction using a stylus and keyboard. We found that interactive surfaces have greater affordance for bimanual interac-tion and we suggest that virtual sculpting could benefit from a combination of stylus and multi-touch interaction in the future.
