| Abstract(in English) | If the system can recognize the user's mental status from his facial expression in the user-system conversation, the system can utilize it for the adequate control of conversation. In this paper, we investigate the facial actions which can be utilized for conversation control, and propose a recognition algorithm for them. From observing conversations between a robot and a user, we can see that the user often shows three facial expressions : "smile", "grimace", and "eyes wide open". These expressions can be used as a sign of misunderstandings and a measure of mental pleasantness of the users. It is also shown that these expressions appear particularly in the mouth, cheek, middle of forehead, eyes and eyebrows. Experimental results of extracting these facial parts and recognizing these facial expressions, 85% accuracy was achieved. |
