Fuzzy reasoning model of facial selection and its applications

Abstract

We have been spending more time on interaction with computer systems in the information-oriented society. Human face-to-face interaction consists of both verbal communication and nonverbal communication such as facial expressions and gestures. Therefore we have adopted facial expressions for human computer interaction. We propose a fuzzy reasoning model for selecting faces expressing emotions caused by several situations. Nine faces with three levels of brow and eye deflection and three levels of mouth deflection were used to construct the fuzzy reasoning model. The fuzzy reasoning model was applied to selecting faces expressing emotions caused by sentences on the computer display. A questionnaire survey reveals the usefulness of our method as a human-computer interface.
