[Abstract]
We investigated how the observer's gaze locations temporally shift over the body parts of a subject in an image when the observer is tasked to evaluate the subject's characteristics. We also investigated how the temporal changes of the gaze locations vary when different characteristic words are contained in the tasks. Previous analytical studies did not consider time-series gaze locations, although they did determine that the initial location that the observer's gaze fixates on is the subject's face. In our analysis, we assigned characteristic evaluation tasks to observers and measured their gaze locations temporally while they viewed human images. We computed the distance from the observer's gaze location to the subject's body part at each time point and evaluated the temporal difference of the distances between the tasks. We found that the observer's gaze fixated on the face initially and shifted to the upper and lower body parts. We determined a common pattern of time-series signals of gaze locations among many participants and individual patterns among a few participants. Furthermore, we found that the temporal changes of the gaze locations became similar or dissimilar according to the characteristic words contained in the tasks.
