Multi-User XR Spherical Model Splicing for Immersive Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current extended reality (XR) technologies cannot provide a 'game companion' function for multiple users, where users cannot view each other's game processes in a field-of-view conversion manner, limiting the immersive experience in multi-user XR environments.
Innovation Solution
A method and apparatus for acquiring and generating an extended reality spherical model by splicing view images from multiple users, allowing each user to display the combined XR scene at their head-mounted device, enabling multi-user XR interaction and immersive experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-player XR game scene is used, then the XR device can display the current user's game process, but it cannot provide a 'game companion' function for multiple users to view each other's game processes
Solution Approach 1:
The patent segments the XR scene into multiple independent spherical model components, each representing a different user's viewpoint. These segmented scene components can be independently processed and then combined to create a composite multi-user XR scene, enabling the system to handle multiple users without overwhelming complexity
Solution Approach 2:
The patent transitions from traditional 2D screen partitioning to a 360-degree spherical coordinate system. By mapping multiple users' viewpoints onto different angular positions in a spherical space, the system accommodates multiple users in a three-dimensional virtual space, allowing each user to view others' game processes from their respective directional perspectives
2Adaptability or versatility
If screen partition display is used for multi-user viewing, then multiple users can see each other's game process, but it requires significant head movement and reduces immersion
Solution Approach 1:
The patent employs a spherical model to represent the complete 360-degree virtual environment. Each user's viewpoint is positioned at a specific angular location on this sphere, allowing other users' game processes to be displayed in the surrounding spherical space rather than requiring screen partitioning. This curved spatial arrangement enables natural head movement while maintaining immersion, as users can look around the spherical environment to view companions without awkward screen switching

AI summary
The present disclosure provides an extended reality display method and apparatus, an electronic device and a storage medium. The extended reality display method includes: acquiring a view image corresponding to each user in response to a trigger operation for multi-user picture sharing; generating an extended reality spherical model according to the view image corresponding to each user, wherein the extended reality spherical model is formed by splicing the view images corresponding to the users; and displaying, at a head-mounted end of each user, a picture corresponding to the extended reality spherical model. By means of the method of the present disclosure, extended reality scenes of a plurality of users can be displayed at the head-mounted end of an extended reality device.
