Abstract
A system can be used for detecting execution of a swimming activity of a user. The system includes a processing unit, a buffer, and an electrostatic-charge-variation sensor configured to sense a variation of electrostatic charge of the user during execution of the swimming activity and to generate a corresponding charge-variation signal. The processing unit is configured to acquire the charge-variation signal, detect a first sub-portion of signal that identifies a basic movement of the swimming activity in the charge-variation signal, store the first sub-portion of signal in the buffer, compute an auto-correlation between the first sub-portion of signal stored in the buffer and a second sub-portion of signal of the charge-variation signal, and detect the presence of the basic movement in the second sub-portion of signal based on a result of the auto-correlation.
