Users, especially when in unfamiliar areas, would appreciate services that provide them with information about their surroundings and objects in the neighborhood. A natural way to find such information is by looking at the objects. Therefore, it would be very useful if Location-based Services could provide a kind of viewer-centric interaction between the users and their surroundings. In this paper, the authors outline iVu.KOM as a framework for running efficient and prompt mobile viewer-centric queries. They describe their concepts of efficiently modeling the geometry that is surrounding the user, and the modeling of the user's field of view using orientation sensors existing in emerging Smartphones.
