Abstract: A control method of an apparatus is provided. The apparatus includes a control unit coupled to a proximity sensor to detect a first distance of a user in a field of view, and coupled to a charge variation sensor to detect an electric/electrostatic charge variation caused by the user in a detection region. The control method includes acquiring a charge variation signal and generating charge variation parameters as a function of the charge variation signal. The control method further includes determining whether a condition on charge variation parameters is verified, and if the condition on charge variation parameters is verified, activating the proximity sensor and acquiring a proximity signal. Proximity parameters are generated as a function of the proximity signal. If a condition on proximity parameters is verified, one or more functionalities of the apparatus are activated.
