在本研究中，我们测量和分析了观看带有字幕的角色时观众的凝视数据，并定量地揭示了气球字幕和固定字幕在信息安全方面的差异。由于气球字幕显示在扬声器的附近，因此视线的移动量比固定字幕减少得多，并且假定扬声器和字幕之间的对应很容易。为了揭示这些效果，从注视时间占总时间的比率、单位时间内视线垂直移动距离(秒)、单位时间内总扫视角度三个角度进行研究。结果表明，与固定字幕相比，气球字幕的视线移动距离更小，伴随的扫视次数也有减少的趋势。
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.
