Detection method of a user of an apparatus for controlling one or more functionalities of the apparatus

A charge variation sensor operatively couplable to an apparatus usable by a user, comprising:

• at least one electrode configured to detect a respective electric or electrostatic charge variation caused by the presence of the user in a detection region of the at least one electrode;
• and
• a control unit electrically couple to the at least one electrode, the control unit being configured to:
• acquire, through the at least one electrode, a charge variation signal indicative of the presence or absence of the user in the detection region;
• generate, as a function of the charge variation signal, one or more feature signals indicative of respective features of the charge variation signal;
• generate, as a function of the one or more feature signals, a movement signal which has a value equal to a first value or to a second value, the first value of the movement signal being indicative of the absence of movement by the user in the detection region and the second value of the movement signal being indicative of a movement of the user in the detection region;
• and
• generate, as a function of the movement signal, a presence signal which has a value equal to a first value or to a second value, the first value of the presence signal being indicative of the absence of the user from the detection region and the second value of the presence signal being indicative of the presence of the user in the detection region.
