In this research, we consider the manipulation of 3D virtual objects consisting of many parts in mixed reality space. We propose a method in which users can pick up only one part of an object they need and observe the relative positions of the parts and the connections between them from various directions. Our method uses metaphors in the real world. User studies showed that our approach helps users to avoid incorrect operations and improves the operational feeling and responsiveness. This paper presents the details of our proposed method and a system that can realize it using gestural inputs.
