Abstract

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.
