电视上的字幕(隐藏字幕)通常放置在屏幕的中央底部。然而，根据基本视频内容(动态字幕)将字幕放置在不同的位置，可能会使整体观看体验不那么脱节，更具沉浸感。本文描述了对听力受损用户进行的这种字幕测试，并对以前收集的眼球跟踪数据进行了新的分析。定性数据表明，动态字幕可以改善用户体验，尽管不是所有类型的字幕用户都可以使用。眼球跟踪数据被分析，以比较字幕用户的凝视模式和没有字幕观看的人的基线。研究发现，观看动态字幕的人的凝视模式比观看传统字幕的人更接近基线。最后，讨论了创作动态字幕时需要考虑的一些因素。
Subtitles (closed captions) on television are typically placed at the bottom-centre of the screen. However, placing subtitles in varying positions, according to the underlying video content (`dynamic subtitles'), has the potential to make the overall viewing experience less disjointed and more immersive. This paper describes the testing of such subtitles with hearing-impaired users, and a new analysis of previously collected eye-tracking data. The qualitative data demonstrates that dynamic subtitles can lead to an improved User Experience, although not for all types of subtitle user. The eye-tracking data was analysed to compare the gaze patterns of subtitle users with a baseline of those for people viewing without subtitles. It was found that gaze patterns of people watching dynamic subtitles were closer to the baseline than those of people watching with traditional subtitles. Finally, some of the factors that need to be considered when authoring dynamic subtitles are discussed.
