The user is independent: he directly selects the object most
interesting for him and immediately obtains information about it.
The Audioguide activates
the Target,
which returns the code linked to the specific audio description.
This is an example of the Audioguide versatility in a typical Museum exhibition:

and a temporary exhibition.
The proximity and compenetration of the three levels
don't cause any difficulty to the visitor,
who can easily choose at any moment the
Target
connected to the specific item of interest.
