Method for generating a multimedia element when reading a medium, terminal, and system

A method for generating a first multimedia element comprising:

• reading a first media on a display of a digital terminal;
• acquiring at least one image of at least one face of a user from an optics of said digital terminal, said acquiring being carried out in real time during the reading of the first media;
• detecting a plurality of characteristic points of the face of the user from at least one acquired image;
• generating at least one physiological parameter from at least one processing of at least one characteristic point detected;
• generating a first multimedia element superimposed on the first media being played on the display, said first multimedia element being determined according to at least the value of the physiological parameter;
• emitting simultaneously to generating a piece of digital data deduced from the value of the physiological parameter, said piece of digital data further comprising a time marker of said first media, said emitting being carried out by means of a communication interface intended for a server collecting said piece of digital data.
