8. An electronic device comprising:
a recognition system including:
a movement sensor configured to provide a movement signal indicative of movement of the electronic device;
an electrostatic charge variation sensor configured to provide a charge variation signal associated with the movement; and
a processor operatively coupled to the movement sensor and the electrostatic charge variation sensor, the processor configured to:
detect an orientation variation of the electronic device indicative of a start of a movement towards a user's ear based on the movement signal;
detect, within a first time interval from the detection of the orientation variation, contact or proximity with the user's ear based on the charge variation signal;
detect, subsequent to detecting the contact or proximity with the user's ear, an orientation of the electronic device compatible with an expected orientation of the electronic device in contact or in proximity with the user's ear during execution of a call, for a duration of a second time interval, based on the movement signal; and
determine, in response to detecting the orientation of the electronic device, a recognition of a gesture of bringing the electronic device to the user's ear; and
a controller coupled to the recognition system, the controller configured to activate corresponding functions upon the recognition of the gesture.
