Abstract :
In This work we introduce new approaches for visual information seeking in video documents. We argue that a discrete visualization of continuous media streams via static keyframes is not sufficient to fulfill all information needs and therefore additional, more interactive techniques are required. We extend the concept of elastic interfaces, which has been used successfully with discrete documents, by applying it to continuous data streams. In addition, we propose a different integration of the elastic browsing functionality called "elastic panning". A first usability test is presented in order to prove its feasibility and to highlight its main advantages, namely the ability to access any position within a file independent of its length, and the smoother visual feedback during navigation compared to a standard slider interface.
