Virtual Reality technology, the complex environment can be a simulated, traditional sports courses at the stadium, equipment, it is due to limitations such as safety, to provide scientific and accurate teaching and learning's, a complex by visualizing the theoretical knowledge in the abstract sport, you can get more technical knowledge. Compared to the traditional physical education activities, simulate sports scene only by generating VR panoramas that cannot be virtual reality technology. Based on this, you can improve the enthusiasm and athletic ability of students effectively. Because of immaturity and high-priced equipment of VR technology, at present, people that education is using unpopular making, carefully virtual reality technology. In this context, we can apply virtual reality technology to sports training, which can obtain more effective training effect. In the first part of this paper, we talk about the research of virtual reality panorama, the second part about the research of virtual reality video, the third part about the application of virtual reality in physical education teaching, and the fourth part is the conclusion and investigation process. In the study, VR, as a new technology, found that you have the prospect of a wide range of applications. As long as it has been used in scientific and rational, you can VR is to promote the level of improvement and sports greatly sports scene. Users can increase users' interest; it can be immersed in a variety of preset virtual locations. Therefore, in the VR device, which allows the user to improve the experience of the VR device, you can interact well in a virtual scene. 相似文献

From visual simulation to virtual reality to games 总被引:3,自引:0,他引:3
During the past decades, the virtual reality community has based its development on a synthesis of earlier work in interactive 3D graphics, user interfaces, and visual simulation. Currently, the VR field is transitioning into work influenced by video games. Because much of the research and development being conducted in the games community parallels the VR community's efforts, it has the potential to affect a greater audience. Given these trends, VR researchers who want their work to remain relevant must realign to focus on game research and development. Leveraging technology from the visual simulation and virtual reality communities, serious games provide a delivery system for organizational video game instruction and training. 相似文献

Building a human‐centered editable world can be fully realized in a virtual environment. Both mixed reality (MR) and virtual reality (VR) are feasible solutions to support the attribute of edition. Based on the current development of MR and VR, we present the vision‐tangible interactive display method and its implementation in both MR and VR. We address the issue of MR and VR together because they are similar regarding the proposed method. The editable mixed and virtual reality system is useful for studies, which exploit it as a platform. In this paper, we construct a virtual reality environment based on the Oculus Rift, and an MR system based on a binocular optical see‐through head‐mounted display. In the MR system about manipulating the Rubik's cube, and the VR system about deforming the virtual objects, the proposed vision‐tangible interactive display method is utilized to provide users with a more immersive environment. Experimental results indicate that the vision‐tangible interactive display method can improve the user experience and can be a promising way to make the virtual environment better. 相似文献
