Web Viewer for Educational VR Contents of 3D Scene Models Supporting VR Goggles

In this paper, the authors introduce web viewers for educational VR contents. Especially, they propose new web viewer for educational VR contents of 3D scene models. Although there have been many types of VR goggles and a lot of entertainment VR contents, there have been a few educational VR contents. To enhance educational efficiency using VR technology, such educational VR contents should be created more and more. On the other hand, many types of scanning devices have been researched and developed, e.g., Lidar scanners, 360VR cameras and so on. Using these scanning devices, 3D data like Point Cloud Data (PCD), 3D model data and 360VR images/videos, can be obtained easily. To use these 3D data for educational VR contents, the authors have already developed viewer applications as web services. These web viewers have functionality to upload 3D data from users' web-browser to the web-server on that the web viewers work. However, 3D scene models are not supported. Standard videos are still important media for the on-demand online educations. Therefore, the authors propose new web viewer for 3D scene models supporting standard videos and VR goggles in this paper.
