One variation of a system for unobtrusively recognizing emotions of users includes: a galvanic skin response sensor; a heart rate sensor; a skin temperature sensor; a motion sensor; and a controller configured to sample a sequence of biosignal values of a user from the galvanic skin response sensor, the heart rate sensor, the skin temperature sensor, and the motion sensor, to implement statistical tests, self-organising maps, and clustering techniques to identify of significant changes in characteristics of the sequence of biosignal values, and to predict an emotional status of the user based on the significant changes in characteristics of the sequence of biosignal values.
