A method for interaction between a mobile terminal and a communicating automaton machine. The communicating automaton machine includes a conversational agent capable of exchanging messages with the terminal by using a first communication interface. The method includes obtaining a piece of information according to which the communicating automaton machine is in the vicinity of the terminal; inserting, in an address book of the terminal, an entry relating to the communicating automaton machine including at least the piece of information obtained; and sending at least one message capable of initializing an interaction between the terminal and the communicating automaton machine when the inserted address book entry is selected.
