The term "interaction process" is understood as a procedure comprising a defined sequence of steps (i.e. a plurality of predefined steps) having the purpose of delivering a determined good or service for the remote user, in which a given step can be executed only after the preceding step has been executed, such as for example in a guided procedure.

The sequence of steps is defined in advance, for example by the client.

The use of a sequence of steps which are defined in advance (i.e. a plurality of predefined steps) provides the advantage to guide the operator to execute a procedure comprising a plurality of predefined steps, so that the operator can't deviate from the procedure, thus avoiding the risk for the operator to skip one or more steps and reducing the risk to forget the collection of important data from the user.

Moreover, the execution of all the steps of the defined sequence allows to collect, store and track data of all the states crossed by the interaction system of the invention, so that said data of the states can be provided later as a proof in case of a dispute by the client.

Moreover, the use of a defined sequence of steps allows to suspend the execution of the procedure at a particular step and then to recover the execution of the procedure at the step wherein the suspension occurred, also in case of different operators between the one who performed the suspension and the one who performed the recovery.

The following are some examples of procedures:

- a procedure for identifying the remote user, to issue a digital certificate associated with the remote user;

a procedure for the remote user to enter into a distance contract; a procedure for the remote user to open a remote bank account.

Alternatively, the interaction process is the sharing of a resource between the operator's electronic device 3 and the user's electronic device 10 (or 1 1 , 12), wherein said sharing allows the execution of a plurality of steps and the use of peripherals installed on the electronic devices that share said resource.

The following are some examples of a shared resource:

- sharing of a form containing fields indicating the remote user's personal data;

sharing of a digital document;

sharing of the same images displayed on a screen connected to the operator's electronic device and on a screen connected to the user's electronic device. In the case of the shared form, the steps consist of the completion of the form fields by the remote user, the completion of the form fields by the operator 3, or deletion of the data entered in the fields by the remote user or the operator 3.

In the case of a shared digital document (e.g., the document is in the pdf format), the steps are for example:

displaying a same page on the screen 3-1 of the operator's electronic device 3 and on the screen 10-1 of the user's electronic device 10 (or 1 1 , 12),

- displaying a same portion of a page on the screen 3-1 of the operator's electronic device 3 and on the screen 10-1 of the user's electronic device 10 (or 1 1 , 12),

highlighting a portion of a page and displaying the highlighted portion on the screen 3-1 of the operator's electronic device 3 and on the screen 10-1 of the user's electronic device 10 (or 1 1 , 12).

Advantageously, the telecommunications network 4 comprises a server 2, which is an electronic device having the function of bidirectionally connecting the operator's electronic device 3 to the user's electronic device 10 and of driving the execution of the interaction processes on said operator's and user's electronic devices, by means of an architecture of client/server type.

Moreover, the operator's electronic device 3 and the user's electronic device 10 are such to exchange text messages by means of an online chat, wherein the text messages are carried through the telecommunications network 4.

Alternatively or in combination with the online chat, the operator's electronic device 3 and the user's electronic device 10 are such to exchange audio messages by means of an online audio chat, wherein the audio messages are carried through said telecommunications network 4.

Alternatively or in combination with the online chat, the operator's electronic device 3 and the user's electronic device 10 are such to exchange audio/video messages by means of an online audio/video chat 3-1 .4, wherein the audio/video messages are carried through said telecommunications network 4.

The term "online" (with reference to a chat) is used to indicate that communication between the operator's electronic device 3 and the user's electronic device 10 by means of text messages, audio messages or audio/video messages takes place substantially in real time.

It is observed that the text, audio or audio/video messages can be exchanged through the telecommunications network 4 by means of a data communication channel that may be the same or different from the communication channel that allows the interaction between operator software application (running on the operator's electronic device 3) and the user software application (running on the user's electronic device 10).

For example, the operator's electronic device 3 and the user's electronic device 10 can consist of one of the following devices:

The graphical user interface 10-1 allows the user 7 to interact with the first user's electronic device 10 by means of text commands and graphical objects.

The graphical user interface 10-1 is for example a screen of LCD or LED type or of the touchscreen type.

The graphical user interface 10-1 , in turn, comprises an area 10-1 .1 having the function of displaying the text messages exchanged between the operator's electronic device 3 and the first user's electronic device 10 by means of the text chat.

Therefore the first user's electronic device 10 communicates in real time with the operator's electronic device 3 by means of the text chat.

In particular, the text messages exchanged between the user's electronic device 10 and the operator's electronic device 3 are displayed simultaneously in the area 10.1 .1 of the graphical user interface 10-1 of the user's electronic device 10 and in the area 3-1 .1 of the graphical user interface 3-1 of the operator's electronic device 3.
