Geolocative Raycasting for real-time buildings detection in pervasive games

The use of augmented reality (AR) becomes increasingly common in mobile game development as a means of enhancing the players´ view of the physical world by computer-generated graphical information. A situation often encountered in AR applications is the -partial or full- occlusion of virtual objects by physical artifacts; if not appropriately handled, the visualization of occluded objects often misleads users´ perception. This paper presents a Geolocative Raycasting technique aiming at assisting developers of outdoors pervasive games into generating a realistic field of view for the players by integrating real time building recognition, so as to address the occlusion problem.
