The processing center: it is the core of the business logic. It accesses, in the Cloud, the cultural contents required by the users and smartly provides such contents on several interactive platforms. Then, it allows the execution of several location-aware services by providing them with the positioning information coming from the localization infrastructure. These services enrich the cultural experience of the users by immersing them in a real interactive environment controlled through the multiprotocol middleware. Moreover, they allow visitors to preserve their memories by interacting with external world and, finally, they also support the management of the museum.
