Multi-scale Mixed Reality Collaboration for Digital Twin

초록

In this poster, we present a digital twin-based mixed reality system for remote collaboration with the size-scaling of the user and the space. The proposed system supports collaboration between an AR host user and a VR remote user by sharing a 3D digital twin of the AR host user. To enhance the coarse authoring of a shared digital twin environment, we provide a size scaling of the digital twin environment with the world-in-miniature view. Also, we enable scaling the size of the VR user’s avatar to enhance both coarse (size-up) and fine-grained (size-down) authoring of the digital twin environment. We describe the system setup, input methods, and interaction methods for scaling space and user.
