Interactive Search in Video: Navigation...

On touch-based devices such as smartphones and tablets users are accustomed to browse through lists and collections by using flick gestures. For video navigation, however, mobile touch devices still use the seeker-bar interaction concept. In this paper, we evaluate the performance of a flick gesture-based video player in direct comparison to a default video player with seeker-bar navigation for the purpose of interactive search in video. We have developed a special video player on a tablet device and performed a user study with 16 users with two different types of interactive search: target/known-item search and scene counting. Our results show that the flick-based video player is less performant than the default video player in terms of search time, but more efficient in finding target scenes and the preferred interface by the vast majority of tested users.
