Augmented reality in-situ 3D model menu for outdoors

We present a design and implementation of an in-situation menu system for loading and visualising 3D models in a physical world context. The menu system uses 3D objects as menu items, and the whole menu is placed within the context of the augmented environment. The use of 3D objects supports the visualisation and placement of 3D models into the augmented world. The menu system employs techniques for the placement of 3D models in two relative coordinate systems: head relative and world relative.
