We present DRAGON, a direct manipulation interaction technique for frame-accurate navigation in video scenes. This benefits tasks such as professional and amateur editing, review of sports footage, forensic analysis By directly dragging objects the scene along their movement trajectory, DRAGON enables users to quickly precisely navigate specific point timeline where an object interest is desired location. Examples include frame sprinter crosses finish line, or car passes traffic light. Through user study, we show that significantly reduces task completion time in-scene by average 19-42% compared standard slider. Qualitative feedback from also positive, with multiple indicating felt more natural than traditional slider navigation.
