The user interface
In the following picture are underlined the most important objects in the interface that we are going to focus on during the whole chapter:

- A pull-down menu from where we can choose the NAS;
- A set composed by five buttons (play, pause, stop, fast forward and backward) useful to manage the song meanwhile it is playing;
- The volume bar useful to manage the volume of the loudspeacker;
- The time bar, highlighted with a white box, which represent an analogic time counter during the song reproductions;
- The songs table, which contains the list of all the songs in the choosen NAS.
These are the main features we are going to talking about in the rest of the chapter. We are going to analyze all the possible aspects from the static, dynamic and interactive point of view.
