☆ Please carefully read the following introductions before doing the user study!
To do:
In this survey, you will need about 10 mins to evaluate the viewing experience of a group of four short video (average 2 minutes long extracted from movie "Up.In.The.Air"). Of these four videos, the first one (Static) is a traditional video with static subtitles at the bottom of the screen while the others three (Dynamic_I, Dynamic_II and Dynamic_III) use dynamic subtitles with different subtitle placement strategies. You need to indicate your preferences in terms of (1) overall level 1~10 (not satisfactory~highly satisfactory); and (2) eyestrain level 1~10 (high eyestrain~low eyestrain), for these four videos. For both scores of overall and eyestrain levels, the higher means the better.
Background:
Subtitles are usually needed when watching foreign movies that are not dubbed. Conventionally, subtitles appear at a fixed position such as the bottom of the screen. As a result, viewers may either miss the flow of visual contents or the subtitles, since it is difficult to focus on both. Dynamic subtitles improve the movie watching experience by placing subtitle near speakers. In this way, viewers can see both video content and subtitles relatively easily, since they no longer need to look back and forth between the bottom of the screen and the faces of speakers. Furthermore, placing subtitles next to the appropriate speaker makes it possible to know who is speaking, especially when there is no audio clue, such as for reviewers with hearing impairment.
Tips:
The audio of all the videos is in Spanish in order to better evaluate the importance of the subtitles to videos;
It is recommended that all the videos be switched to the best video quality and watched in the full screen mode on a desktop PC or a laptop PC, rather than in a reduced size or on a mobile device, because the distance between subtitles and speakers' faces is an important factor of this user study.
