TARBoard: Tangible Augmented Reality System for Table-top Game Environment ∗
Wonwoo Lee, Woontack Woo, Jong Weon Lee · 2005
In this paper, we propose TARBoard which is a tangible augmented reality system designed for table-top game environment. The objective of TARBoard system is to let users fashion the board or card game in a more interactive and intuitive way. To achieve this goal, TARBoard adopt two features, augmented reality and tangible user interface. Augmented reality makes the game more realistic and interactive and tangible user interface enables users to interact with virtual objects in the game intuitively. TARBoard consists of a glass table, two cameras and a mirror. Markers are attached to the bottom of objects or cards used in a game. A camera is for tracking markers and the other camera is for augmenting virtual objects. The proposed system separates the tracking camera from the augmenting camera. The tracking camera tracks the image of markers reflected in the mirror below the glass table. The augmenting camera provides images where the virtual objects are augmented. As a result, TARBoard avoids occlusion problem in table-top augmented reality environment. In addition, TARBoard allows various types of objects to be used as tangible user interface, instead of cubes or flat panels which are frequently used in tangible augmented reality.
