[PEM10-07] Development of a 3D object sharing system of plasma motions using XR technology for educational supports of space-plasma environments
キーワード：教育DX、空間共有、地球電磁環境
Electromagnetic fields and particle motions in space-plasma environments are complex and invisible. Effective drawing plasma motions can make it easier for learners to deeply understand the physical laws. We have developed a visualization system of 3D plasma motions in space-plasma environments using XR (Cross Reality) technology. XR is a generic term for technologies that allow users to experience virtual worlds through display devices. This system has an advantage of displaying scientific data in XR, which makes it easy to view of the 3D model from different perspectives. However, since only one user can view the displayed data in the system of the previous research, it is not suitable for group learning. We have developed a 3D object sharing system that allows each user to view objects in a virtual space from a different physical perspective. This research uses an XR head-mounted display "Microsoft HoloLens2" for input and output operations. Our system is built using Mixed Reality Toolkit, which is an XR framework, Mirror, which is a networking library, and Unity, which is a game engine. We use Microsoft's Azure Spatial Anchors service to share a physical reference point. We created a script to calculate each user's perspective to share an object's position, rotation and size. In this presentation, we will explain how the system works and demonstrate 3D particle motions such as gyro, mirror, and drift motions in the magnetosphere.
