Patch-based Video Browsing.

Interacting with video content can be very time-consuming, and solutions are needed to support people in the process of browsing a video so that they can efficiently interact with the video content. Based on information foraging theory, we have developed a video content browsing tool. Video content is accessed by means of “patches”, which provide interaction with the video document that partly surpasses the burden of video’s time-based nature. Patches can be of various types and can be combined using logical operators. Within-patch and between-patches browsing behaviour is well supported. The browsing process is considered to be the (fast) alternation between metadata-driven and data-driven interaction. The current application’s priority is to support this browsing process. Preliminary test results indicate that a “patch–approach” is very fruitful. Important research issues are identified related to video content descriptions and browsing behaviour.
