1. A system comprising:
an electrostatic charge variation sensor, configured to detect a variation of an electrostatic charge of a user of an electronic device during execution of a gesture by the user, and to generate a charge variation signal, wherein the gesture includes the user moving at least one foot upward and, subsequently, downward; and
a processing unit, coupled to the electrostatic charge variation sensor, and configured to:
acquire the charge variation signal;
calculate a derivative function of the charge variation signal;
detect, in the derivative function of the charge variation signal, a first characteristic identifying the gesture of moving the at least one foot upward, the first characteristic including a first negative peak temporally followed by a first positive peak;
detect, in the derivative function of the charge variation signal, a second characteristic identifying the gesture of moving the at least one foot downward, the second characteristic including a second positive peak temporally following the first positive peak and temporally followed by a second negative peak; and
control at least one functionality of the electronic device in response to detecting both the first and the second characteristics.
