Abstract
As a recent trends in 3D modeling environments, they implement simultaneous editing through network by multiple people. Furthermore, multiple people are able to create 3D model with communicating online or in VR space by using these 3D modeling environments. On the other hand, in the case of modeling by collaborating with some users in real space, users need to share the display or multiple work environments are required. In this study, we propose FabKUI, a modeling method that enables multiple people to share a single interface in real space and collaborate on 3D modeling by using smartphone AR. In the proposed method, the concept of shadow user interface enables to control 3D movement of the entity by manipulation of shadows. And 3D models can be generated from 3D trajectories of the movement of the entity. Because of the application of KUI, FabKUI enable to create 3D models as if handwriting. In addition, by superimposing the 3D model generated in the real space using smartphone AR, it is possible for multiple people to view the 3D model. In this paper, we show the way of implementation of the proposed method and demonstrate the effectiveness of the system from the results of evaluation experiments.
