MagicCup: a tangible interface for virtual objects manipulation in table-top augmented reality

We propose a tangible interface for virtual object manipulation in table-top augmented reality based on ARToolKit. It is designed for city planning. Augmented reality technology enables users to consider city plans more effectively and easily. One important issue of the augmented reality environment is how a user can manipulate 3D structures that are displayed as virtual objects. It has to be intuitive and easy so that it may not disturb a user's thoughts. We propose a new direct manipulation method based on a tangible user interface. The user holds a transport cup upside down and can pick up, move or delete a virtual object.
