Touch & Detach: Ungrouping and observation methods for complex virtual objects using an elastic metaphor

In this study, we implemented a stable and intuitive detach method named “Touch & Detach” for 3D complex virtual objects. In typical modeling software, parts of a complex 3D object are grouped for efficient operation, and ungrouped for observing or manipulating a part in detail. Our method uses elastic metaphors to prevent incorrect operations and to improve the operational feel and responsiveness. In addition, our method can represent the connection and its strength between the parts by simulating a virtual elastic band connecting the parts. It helps users to understand the relationship between the parts of a complex virtual object. This paper presents the details of our proposed method and user study.
