In the first case, an audio-streaming server application provides the interested clients with the audio contents related to the observed artwork. In the second case, the processing server exploits the wired local networks to send multimedia contents to interactive displays and totems in the museum, so that the same cultural information is simultaneously available to all the involved users. The processing center takes the decision depending on a threshold algorithm that constantly monitors the number of simultaneous visitors looking the same artwork. More in detail, when the number of visitors is below a predetermined threshold, the algorithm converges to the first alternative. On the contrary, if there is a large group of visitors sharing the same “visiting experience”, the algorithm converges to the second alternative.
