DRAGON allows users to navigate through videos by directly dragging objects in the footage.
Video players usually provide a timeline slider for moving the playback position in a video. However, this slider does not reflect the spatial movement of objects in the footage. DRAGON is a direct manipulation technique for precise in-scene video navigation. It allows users to directly click on objects in a scene and browse in the video by dragging alongside the objects’ trajectories. Thereby, users can navigate to events with spatial meaning, e.g., to the position where a sprinter crosses the finish line.
