People-to-People-to-Geographical-Places systems connect places to communities. Generally, these systems require users to perform complex tasks using mobile phones. Thus, the creation of powerful interaction techniques and the design of effective and easy interfaces are key requirements. The system, the authors propose in this paper, named SmartBuilding, is a mobile Augmented Reality system that supports the sharing of contextualized information in indoor environment, depending on the user location. This system shifts the interaction with the user from the classical desktop logical metaphors towards a more natural interaction style based on augmenting and annotating an indoor environment.
