Resumen
Device and method of stress detection by physiological signals comprising an enrollment stage and an access stage. The enrollment includes: obtaining, for different mood states of the user, hr (heart rate) and gsr (galvanic skin response) signals; store the signals; execute a clustering algorithm to obtain a stress pattern associated with the user and store said stress pattern for later identification. The access stage comprises: performing identification tasks of the user; obtain the stress pattern corresponding to the previously identified user; obtain the hr and gsr signals of the current mood of the user; store the obtained access signals; execute a clustering algorithm to obtain an access stress pattern; compare the access stress pattern with the stored stress pattern for the user and decide the degree of user stress.
