Development of direct manipulation interface for collaborative VR/MR workspace

Our research projects aim to connect various VR/MR platforms and to realize the seamless collaborative works with the intuitive operations whenever and wherever users like. In order to realize an ideal collaborative workspace, an effective handling scheme for both interactive virtual objects and system operation of VR/MR platform is needed. In this paper, we describe the three components, which are the direct manipulation interfaces for potable MR space and for fixed shared VR/MR space, and Interactive 3D Marker for displaying and manipulating virtual objects reflected lighting and geometry conditions of the real world. These components can give users seamless manipulation workspace by the natural operations such as they behave in their daily life. We also introduce Interactive Interior Design System using these components. This system realizes to coordinate the suitable interiors in the real space, by the free manipulation of virtual interior objects reflected the geometry and the lighting condition of the real space.
