Ergonomics Research On Color Bar-based Affective Annotation Method Implementing On Media Player

Nowadays, people watch movies, TVs, sports games, etc. on their PCs, they also watch them over the internet. People used to watch them in time order but they now don't. They always try to figure out what the video is about and which part they will have most interest in.The traditional media players offer a slider control in the interface to show the progress of the video and for the users to drag it to any position of the video as their wish. However, the traditional slider does not provide any clue of the content of the video. It cannot tell which part is the most interesting part that the users might want to find out. The users have to waste much time to find it out by dragging the thumb of the slider back and forth.Considering this, we proposed a color bar based affective annotation method and applied it to a media player, EmoPlayer. It demonstrates the emotions of the roles in a movie clip. A color bar is placed above the slider and used for demonstrating different emotions of the roles at different time points, in accordance with the slider bar. Colors on the color bar spanning different time periods in a series of color blocks, represent different kinds of affects. All such information about the distribution of affects of different roles is organized and recorded in an XML-formed file. In addition, we set up two experiments to examine the effect of affective annotation in quick locating and 'watching comprehension' jobs. The results demonstrated that the affective annotation improved the efficiency of both of them. It really helped in the process of interaction. After that, we also held a discussion about the procedure of the experiments and the behavior of the subjects. We concluded several strategies the subject might use while carrying out the tasks.
