System for monitoring the physical activity of a user, a portable medium and a method for monitoring

A system (1) for monitoring physical activity of a user (2), comprising:

• a portable medium (3) which can be worn by the user (2) and which is equipped with:
• a sensor (4) designed to detect a signal relating to movement of the user (2);
• a power supply (5);
• a display unit (6) of the portable medium;
• a data storage memory (7);
• an interface (8) which can be coupled to a gym machine (9) and which is configured to allow data to be exchanged between the memory (7) and the gym machine (9);
• a processor (11) programmed for deriving in real time, at least from the signal detected by the sensor (4), a dimensionless parameter value representing the physical activity of the user (2) wearing the portable medium (3) and for displaying, on the display unit (6), an indication, as a function of the derived value of the dimensionless parameter and of a reference value of the dimensionless parameter constituting a preset target for an amount of physical activity to be performed by the user (2) in a predetermined time interval;
• a remote server (12) having access to a database (13) containing data received from the portable medium (3),
• characterized in that the portable medium (3) comprises wireless communication means (10) configured to establish a short-range connection (C1) between the portable medium (3) and a mobile telephone (14), the mobile telephone (14) being equipped with a display unit (15) and being set up to establish an Internet connection (I1) and to connect up to the remote server (12) through the Internet connection (I1) in order to transfer data in real time to the remote server (12) through the Internet connection (I1),
• the remote server (12) being programmed to transmit, in real time through the Internet connection (I1), motivational indications as a function of the data transmitted by the portable medium (3) to the remote server (12), so that the motivational indications are displayed on the display unit (15) of the mobile telephone (14),
• wherein motivational indications are derived in real time from the data transmitted by the portable medium (3) to the remote server (12) through the short-range connection (C1) and the Internet connection (I1), wherein said data comprise said dimensionless parameter, representative of the amount of physical activity carried out by the user during a day, and said reference value of the dimensionless parameter.
