Emotion detection method and system based on change in resistance of human skin

The present invention discloses a method and system for detecting emotion based on change in resistance of human skin, the method according to the present invention comprises the steps of: initializing parameters, body resistance data collected, data analysis, the value of the emotional state feedback to the user; analyzing said data comprises a pre- treatment and threshold analysis, slope analysis, analysis with slope and duration, slope, duration, and analysis with a threshold value. Medical system of the invention comprises pole pieces are sequentially connected, the bridge resistance / conductance measurement circuit, an amplifier circuit, A / D conversion circuit, CPU, and man-machine interface. The present invention employs an adaptive algorithm, the magnitude of a resistance, a slope and a state variable duration to reflect emotional problems overcome individual differences, the reaction testers finer degree of excitement.
