SYSTEM TO DETERMINE AN EMOTIONAL STATE OF A USER (MACHINE-TRANSLATION BY GOOGLE TRANSLATE, NOT LEGALLY BINDING)

System to determine an emotional state of a user, characterized in that it comprises: - a first portable device (1) that has sensor means (5) configured to acquire a set of physiological signals (51) from the user, where the first portable device comprises: a first processor module (50) configured to: determining, from the set of physiological signals, a first partial emotional state with a first level (57) of said emotional state; determining if the first partial emotional state coincides with a previously established target emotional state through a dynamic and machine learning algorithm and if the first level of the first partial emotional state exceeds a previously established first threshold; and transmitting, if so, an alarm message to a mobile communication device of the user together with the physiological signals; - a second portable device (2) configured to acquire an audio signal (60) upon receiving an activation instruction from a mobile communication device of the user; - a second processor module (62) configured to determine, from the audio signal, a second partial emotional state with a second level (66) of said emotional state, and to determine if it coincides with the target emotional state and if it exceeds a second previously established threshold; and - a mobile communication device (3) comprising: - a wireless communication module (6) configured to receive the alarm message from the first portable device and send the activation instruction to the second portable device; and - an analyzer module (47) configured to determine, in case the second analyzer module indicates that the second level has exceeded the second threshold, the presence of the target emotional state in the user, based on an analysis of the levels of the states emotional partial (57, 66) by the dynamic and machine learning algorithm.
