One of the main tasks of the services running on the processing center is to adapt the status of the environment according to the information coming from the localization service. More in detail, exploiting IoT-aware technologies, the environment could be modified in real-time in order to provide the user with a real interactive experience. As an example, imagine that the museum has a special room where an historical war is represented by a mechanical animation managed by several IoT actuators. To maximize the impact of this animation, the system could decide to activate it only when the number of visitors in the room is higher than a predefined threshold. In the same way, lighting, temperature and other physical characteristics of a room could be controlled to automatically perform special effects typical of a 4D cinema. Obviously, the IoT technologies able to provide these features could be extremely heterogeneous since they are often compliant to different standards and protocols.
