Abstract
This research is the first attempt to analyze how the gaze behavior during turn-keeping/changing changes depending on empathy skill, which is measured by using Davis' Interpersonal Reactivity Index (IRI). The representative results of the analysis of the gaze behavior and empathy skill showed that current speakers and next speakers with a high empathy skill level usually do not look at other people during turn-keeping or turn-changing. In contrast, speakers with a low empathy skill level often continue to make eye contact with listener during turn-keeping and turn-changing. Moreover, listeners with a low empathy skill level often look at the speaker unilaterally during turn-keeping and do not look at others during turn-changing. These are new findings. On the basis of these findings, we constructed four estimation models of the four-scale value of empathy skill levels by using gaze behaviors. The evaluation results showed that the average absolute error of estimation is only 0.22 for the gaze transition pattern (GTP) model.
