<p>In this study, we measure and analyze viewer's gaze data when watching characters with subtitles, and reveal the differences in information secure by balloon captions and fixed subtitles quantitatively. Since the balloon caption is displayed in the vicinity of the speaker, the amount of movement of the line of sight is reduced more than the fixed subtitle, and it is presumed that the correspondence between the speaker and the subtitle is easy. In order to reveal these effectiveness, from the three viewpoints; fixation time ratio to total, time line of sight vertical movement distance per unit time(sec), total saccade angle with unit time. As a result, it was revealed that the balloon caption tends to have a smaller gaze moving distance of the viewer than the fixed subtitle, accompanying saccade tends to decrease.</p>
