| In recent years, various user interfaces using AR have been developed. However, there is no research which realizes collaboration in 3D space by Tangible user interface. Tangible user interface is to perceive and operate insubstantial digital information directly by hand. Therefore, in this research, we develop a system where projected 3D object in HoloStage can operated directly by multiple persons using tangible AR. Definition of tangible AR is to touch object directly by hand in 3D space. We use the RGB camera and depth sensor of Kinect in order to operate the 3D object. In this paper, it is introduced that a collaboration system is implement the tangible AR system. |
