Tangible User Interface for CAVE based on Augmented Reality Technique - Tapa blanda

Sinopsis

This thesis presents a new 3D user interface system for CAVE application, based on Virtual Reality (VR), Augmented Reality (AR), and Tangible User Interface (TUI). We explore fundamental 3D interaction tasks with our user interface for the CAVE system. User interface (UI) is comprised of a specific set of components, including input/output devices and interaction techniques. Our approach is based on TUIs using ARToolKit. Physical objects (props) are used as input devices instead of any tethered electromagnetic trackers. An off-the-shelf webcam is used to get tracking input data. The user can actually feel the prop's movement through the virtual space. Thus, fundamental 3D interaction tasks such as object selection, object manipulation, and navigation are performed with our interface. The results from our user studies show that our interface can be intuitively and naturally applied to 3D immersive environments even though there are still some issues with our system design. This thesis shows that effective interactions in a CAVE system can be generated using AR technique and tangible objects. iii
