Abstract
Mentality estimation system on affinity pleasure-arousal space using fuzzy inference is proposed for the communication between human beings and an eye robot agent. Mentality status on the proposed space is calculated by fuzzy inference which uses language category as outputs of speech understanding. The constructed eye robot system expresses mentality on the space by eyelid and ocular moving which is defined in advance. Experiments of mentality expression with two scenarios are done. Since the result of questionnaire shows that evaluation value is 3.6 out of 5.0, the proposed system is suitable for communication architecture between interlocutor and robot. The system provides the information terminal robot that becomes common in home environment.
