A portable device (1), method and program product for generating a parameter related to the physical activity of a user. The device (1) includes at least one sensor (2) configured to measure information representative of the movement of the user. The sensor (2) is configured to generate, on the basis of such information, a plurality of values of physical activity data. A data processing unit (3) of the device (1), operatively connected to said at least one sensor (2), is configured to generate at least one physical activity rate parameter on the basis of said plurality of values of physical activity data generated by said at least one sensor (2). The data processing unit (3) is further configured to generate said at least one physical activity rate parameter in a first reference time instant on the basis of a portion of values of said plurality of values of physical activity data generated by said at least one sensor (2) in a set period of time preceding the first reference time instant t0. |
