Abstract:With the exploration of video data, it is difficult for people to navigate freely and make full use of amount of video data efficiently in order to get useful information or knowledge with an aim to fulfill special tasks such as visual analysis. In this paper, we propose a novel sketch based interface which is called StroyMap for video content representation and navigation under the guideline of distributed cognition. Instead of emphasizing on details, the sketches visualized the essential content of video effectively. In order to meet different requirement for video exploration tasks, StoryMap provides users a variety of navigation ways, such as path redirection, map tagging, zoom in and zoom out. During the whole interaction process, the system will collect user's operation list, construct user model as a guide to understand interaction between people and computer. Experimental evaluation results show that StoryMap plays more effiective role in conveying and navigating video content compared with existing methods.
