Publication number: 20250208890Abstract: An XR application development system includes a runtime container, a content generator, and an application generation platform. The runtime container is integrated into the content generator, which generates the application content for the XR application based on the runtime environment provided by the runtime container. When the application content is generated, the application generation platform generates the XR application based on the application content and the runtime container. The runtime container operates between the application content and the operating system, providing a runtime environment for the application content. By adding the runtime container between the application content and the operating system, the strong dependency between the application content and the operating system is eliminated, enabling cross-platform and cross-device development and execution of XR applications.Type: ApplicationFiled: March 7, 2025Publication date: June 26, 2025Inventors: Chengfei LYU, Fei WU, Ziqi WU, Yutong XIU, Yu CAI, Chaoyue NIU
