The continuous growth of media databases necessitates development of novel visualization and interaction techniques to support management of these collections. We present <i>Videotater</i>, an experimental tool for a Tablet PC that supports the efficient and intuitive navigation, selection, segmentation, and tagging of video. Our veridical representation(More)
