Abstract

A Mentality expression system based on the affinity pleasure-arousal space of eye robots is proposed for the communication between human beings and households robots. Mentality status in the proposed space is calculated by a fuzzy inference method that uses language category as the output of a speech understanding module. The constructed eye robot system expresses mentality in the affinity-pleasure-arousal space by predefined eyelid and ocular movements. Mentality expression experiments with two scenarios are performed. Since the results of an evaluation questionnaire show an average evaluation value of 3.6 out of 5.0, the proposed system is suitable for a communication architecture between interlocutor and robot. The system provides a basic interface for an information terminal in home environments.
