我们提出了一种浏览视频的方法，通过直接拖动其内容。这种方法为通常由小部件介导的活动带来了直接操作的好处。我们通过以下方式支持这种新型的交互：1）自动从视频中提取运动数据; 2）一种名为相对流拖动的新技术，允许用户通过沿着其视觉轨迹移动感兴趣的对象来控制视频播放。我们表明，这种方法可以优于传统的搜索器栏在视频浏览任务，专注于视觉内容，而不是时间。
We present a method for browsing videos by directly dragging their content. This method brings the benefits of direct manipulation to an activity typically mediated by widgets. We support this new type of interactivity by: 1) automatically extracting motion data from videos; and 2) a new technique called relative flow dragging that lets users control video playback by moving objects of interest along their visual trajectory. We show that this method can outperform the traditional seeker bar in video browsing tasks that focus on visual content rather than time.
