Touch & detach: physics-based unbinding and observation of complex virtual objects in 3d space

The main contribution of this study is the stable and intuitive detach method, named "Touch & Detach," for 3D complex virtual objects using gesture-based operations in mixed reality space. In general modeling software, parts of a complex 3D object are grouped in a multi-level hierarchy for efficient operation and ungrouping is necessary for observing or manipulating a part in detail. Our method uses real-world bond metaphors (such as glue or a joint) to prevent incorrect operations and improve the system's operational feeling and responsiveness. This paper presents the details of our proposed method and an informal user study.
