USER CONTEXT AND ACTIVITY DETECTION DEVICE AND METHOD

A user context and/or activity detection device (1) envisages a pressure sensor (2), configured to provide a pressure signal (Sp) ; an electrostatic-charge-variation sensor (4), configured to provide a charge-variation signal (S) indicative of a variation of electrostatic charge associated with the user; and a processing unit (6), which is coupled to the pressure sensor (2) and to the electrostatic-charge-variation sensor (4) so as to receive the pressure signal (S) and the charge-variation signal (S) and is configured to jointly process the pressure signal (Sp) and charge-variation signal (S) for detecting changes in level or altitude.
