Augmented Reality (AR) and Tangible User Interface (TUI) have been proven to provide intuition to human computer interface with richness of a tactile sense. Current implementations of the fields, however, have inherited 2D Graphical User Interface (GUI) scheme and worked as isolated systems. Consequently, the systems don't support an intuitive interface and limit fusibility of them. This paper presents an AR-based tangible interaction system for a table-top interaction environment which exploits user context. A projector under the table projects information or scenes onto the table to enhance user's interface. Two cameras on and under the table track tangible objects that are attached with ARToolKit markers and that are used as interaction tools. Furthermore, an augmentation display beside the table shows the real table which is combined with graphical objects. The augmentation is based on user context, and the system shares tracking information of the object as context through vr-UCAM [6]. Moreover, we also present a scheme to enhance the resolution of tracking information based on a tracking prediction using Kalman Filter. For the experiment, we have implemented a virtual world navigation system. The proposed system works as a common interface, therefore is applicable to a wide range of usages such as virtual reality and augmented reality applications.
