and monitor them for a time period to perceive an emotional state of the user,
wherein the emotion recognition unit comprises:
a feature analyzer analyzes features of the physiological signals and generate feature values corresponding to the results
of the analysis;
a subtractor obtains differences between the feature values of the results generated by the feature analyzer and feature values
used as a standard to perceive an emotional state of the user; and
an emotion classifier analyzes the differences obtained by the subtractor to classify an emotion into a plurality of emotional
categories to perceive an emotional category exhibiting the greatest intensity to be an emotional state of the user.
