Facial expression recognition interaction method between mobile machine and human

PURPOSE: An interaction method of a portable apparatus is provided to recognize the expression of a user using an expression recognition algorithm in portable apparatus environment. CONSTITUTION: A user face is captured by the camera of a portable apparatus based on real-time face detection and an expression recognition algorithm(S10). A face image is analyzed using an expression AdaBoost recognition unit and is classified using the output of a recognition value(S20). The program output of the portable apparatus is controlled using the output value and takes a photograph of the expression of a user in real-time(S30).
