PoseAsQuery: Full-Body Interface for Repeated Observation of a Person in a Video with Ambiguous Pose Indexes and Performed Poses

PoseAsQuery is an interactive browsing system used to repeatedly replay any specific segment of a video. To acquire and improve the body control skills that are essential for physical performance, it is necessary to continuously observe an individual's movement. However, previous research has several issues on the ability to repeatedly observe a user's movement without interruption during personal training. For these scenarios, the proposed system simultaneously provides a pose-based browsing method and its interface. The user can pin any frame from which a replay starts by using the person's body movement without another operation, such as pressing a button, that is not essential for improving the skill. The experimental results suggest that users can use posture to decide where to start replaying when they know that the corresponding pose enables them to replay the scene. We concluded that the proposed method enables users to repeatedly observe scenes more efficiently and in a less stressful way than pressing a button to replay from a fixed scene.
