Publication number: 20240087238Abstract: Aspects herein provide a system, media, and methods for a mobile edge computer that renders extended reality (XR) in support of a local user device, via a local network. The mobile edge computer can continue to provide updated XR renderings in near real-time when user position data remains within a particular viewing angle, without requesting updated content or rendering assistance from a remote application. When user position data is determined to be outside of the viewing angle, then the mobile edge computer may request additional content from the remote application.Type: ApplicationFiled: June 21, 2022Publication date: March 14, 2024Inventors: Zheng CAI, Zheng FANG, Yu WANG, David Zhijun SUN
