We present the ZoomSlider, a new interface for skimming and browsing video content in a flexible and interactive way. It circumvents common problems of existing video browsing approaches, such as their lack of scalability to large document sizes and unpleasant because jerky visual feedback. With the ZoomSlider a user can visually skim through video files at different granularity levels thus providing the power and flexibility needed for highly interactive tasks. First usability tests are presented in order to prove the feasibility of the overall concept.

In this demonstration we present three interface designs which enable users to visually browse video data by moving a slider thumb along the timeline. In such a case, scrolling granularity is usually limited because of the fixed length of the corresponding slider. In contrast, our interaction designs enable users to skim the data at different granularity levels by providing the possibility to continuously change the slider's scale, by using a nonlinear scale, and by enabling interactive manipulation of the scrolling speed, respectively.
