Temporal Manipulation Interface of Motion Data for Movement Observation in a Personal Training

In this paper, we propose a observation method to easily distinguish the temporal changes of three-dimensional (3D) motions and its temporal manipulation interface. Conventional motion observation methods have several limitations when observing 3D motion data. Direct Manipulation (DM) interface is suitable for observing the temporal features of videos. Besides, it is suitable for daily use because it does not require learning any special operations. Our aim is to introduce DM into 3D motion observation without losing these advantage by mapping temporal changes into the specific vector in 3D space in the real-space.
