TSF-Slider: Combining Time- and Structure-Based Media Navigation in One Navigation Component

Most state-of-the-art interfaces for multimedia browsing come with two inherently different navigation components: a time-based slider interface and a structure based overview. This demonstration introduces the Tempo-Structural-Fisheye-Slider (TSF-Slider). The TSF-Slider combines time- and structure-based navigation in one single navigation component. To merge time- and structure based navigation information, a fisheye based approach is used. The idea of fisheye visualization is extended to rescale time-based information so that it can be merged with structural information while maintaining the general advantages of fisheye visualizations: focusing on one area of interest while still maintaining a general overview. The main motivation for TSF-Slider is, however, that it brings together the advantages of time- and structure based navigation. The TSF-Slider is implemented in the context of the virt Presenter web lecture framework.
