Virtual Diorama (VD) interface is a new Mixed-Reality interface for mobile device, which enables users spread in large outdoor environment to share their point of interest (POI) among users. The outdoor environment is modeled in CG and POI is attached onto the CG model. Users will see POI by maneuvering the CG model (VD model). In this paper, we conduct user study and experiment for usability of our VD interface for better recognition of POI location. We compare two repositioning methods of VD model; Free shot and Dolly-round/Crane (D/C) shot. We also evaluate the usability of superimposing VD model onto the real image. As a result, D/C shot is more suitable than Free shot on our VD interface. We also found that about half of the subjects prefer superimposing of VD model onto real image.
