Abstract - We propose an interactive 4D visualization (3D with an additional time dimension) for the purpose of understanding rapid motion in Dynamic 3D Information. With an interactive 4D visualization, not only the user can observe dynamic 3D motion from different viewpoints, but also the user can adapt the speed of visualization on each viewpoint freely. We developed a system by reconstructing 3D data from RGBD camera into VR environment so that the user can visualize the 3D information via HMD. The experiment result shows that our proposed system outperforms conventional 2D and 3D visualization in term of both user's recognition time and accuracy when observing rapid motion.
