System and method for recognizing user's emotional state using short-time monitoring of physiological signals
First Claim
1. An emotion recognition system, comprising:
- a physiological signal acquiring unit adapted to acquire one or more physiological signals from a user and wirelessly transmit the acquired physiological signals, the physiological signal acquiring unit being worn on the body of the user; and
an emotion recognition unit adapted to receive the physiological signals transmitted from the physiological signal acquiring unit and monitor them for a short time period to perceive an emotional state of the user.

Abstract
Disclosed is an emotion recognition apparatus and method thereof which enables perception of a user'"'"'s emotional state by monitoring one or more of his or her physiological signals. The emotion recognition apparatus comprises a feature analyzer adapted to analyze features of the physiological signals acquired from a user and generate feature values, a subtractor adapted to obtain differences between the feature values generated by the feature analyzer and feature values used as a standard to perceive an emotional state of the user, and an emotion classifier adapted to analyze the differences obtained by the subtractor and classify an emotion into a plurality of emotional categories so as to perceive an emotional category exhibiting the greatest intensity to be the emotional state of the user.

22. An emotion recognition method, comprising the acts of:
-
receiving one or more physiological signals from a user;
analyzing the received physiological signals and extracting a plurality of feature values to be used for recognition of an emotional state of the user in response to the result of analyzing the received physiological signals;
calculating differences between the extracted plurality of feature values and predetermined feature values used as a standard to perceive an emotional state of the user;
classifying an emotional state of the user into a plurality of emotional categories in response to the calculated differences; and
selecting an emotion exhibiting the greatest intensity among the classified emotional categories as a resultant emotional state of the user and outputting the selected emotion. - View Dependent Claims (23, 24, 25)
