In this paper we propose the Keyframe Navigation Tree (KNT) as navigational aid in video for interactive search. The KNT is a hierarchical visualization of keyframes that can compactly represent the content of a video with different levels of details. It can be used as an alternative, or in addition, to a common seeker-bar of a video player. Through a user study with 20 participants we show that the proposed navigation approach not only allows significantly faster interactive search in video than a common video player, but also requires significantly less effort (also less mental and physical load) and is much more enjoyable to use.
