Emotion-oriented human-computer interaction

Abstract

In the information-oriented society, people spend a lot of time interacting with computer systems. Therefore, we need to develop devices which make it a pleasure to interact with computer systems. In human face-to-face communication, nonverbal messages such as facial expressions, gestures, body movements, and postures can convey a speaker's emotions better than verbal messages. Among verbal messages, chiming in to express a listener's support and repeating the speaker's utterances can convey the listener's emotions, encourage the speaker to continue his/her talk, and make the conversation go smoothly. Therefore, we have developed several human-computer interactive systems using facial expressions as a human interface, and have constructed a human-computer interface which chimed in with the user and repeated the user's responses. © 2011 Springer-Verlag London Limited.
