This demonstration shows a city-planning system based on augmented reality with tangible user interface. Miniature models, illustrations and graphical computer displays have been used for the comparison and consideration in city-planning process. Augmented reality technology enables users to consider city plans more effectively and easily. One important issue of the augmented reality environment is how user can manipulate 3D structures that are displayed as virtual objects. It has to be intuitive and easy so that it may not disturb user's thought. We propose a new direct manipulation method based on the concept called tangible user interface. User holds a transparent cup upside down and can pick up, move or delete a virtual object by using it.
