The paper illustrates the potential of smart-phones as a medium of exchange of memories and experiences. Our application aims at providing diverse types of cultural user experience: to enable tourists to explore new places from a social-driven perceptive; to support new forms of connection and interaction between users and information (data exchange, contents sharing, feedback); to compose interactive narrative conveying the richness of information of interest to the user; to allow users to experience the narrative and underlying physical environment as a mixed-reality experience while allowing for deeper, context-specific exploration at any time through AR system.
