Shared XR Asset Viewing With Synchronized 3D Perspective
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collaborative VR environments limit users to discrete viewpoints, restricting shared viewing experiences and impairing collaborative work by not allowing all users to see the same perspective of an asset or interact with each other's avatars effectively.
Innovation Solution
Implementing a shared perspective viewing mode in extended reality (XR) environments where assets are rotated to match users' frames of reference, and avatars are positioned and oriented to maintain a spatial relationship while allowing users to see each other from different angles, using tools like VR/AR devices and interactive input methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users are provided with discrete individual viewpoints in VR environment, then each user can see their own perspective clearly, but all users cannot see the same perspective of an asset simultaneously
Solution Approach 1:
Instead of having users view assets from their own discrete perspectives, the system inverts the approach by providing all users with an identical shared perspective view of the asset. The asset is rendered once from a common viewpoint and displayed to all users simultaneously, enabling collaborative viewing while maintaining individual avatar spatial relationships.
Solution Approach 2:
The system separates the asset viewing dimension from the avatar interaction dimension. Users share the same perspective dimension for viewing assets while maintaining independent spatial positioning in the avatar dimension, allowing both shared content viewing and individual user presence to coexist.
2Adaptability or versatility
If avatars are positioned at the same location to share perspective, then users can see the same asset view, but spatial relationship between users is lost
Solution Approach 1:
The system segments the virtual environment into two independent components: asset viewing space and avatar interaction space. The asset viewing perspective is shared and identical for all users, while avatar positions are maintained separately in their own spatial relationships, preventing loss of user presence information.
Solution Approach 2:
The system introduces an intermediary rendering mechanism that translates individual user perspectives into a unified shared view for assets, while simultaneously preserving individual avatar spatial positions. This intermediary layer reconciles the conflict between shared viewing and spatial relationship maintenance.
3Reliability
If users have different individual perspectives, then spatial relationship between users is maintained, but collaborative efficiency is reduced
Solution Approach 1:
The system applies different quality characteristics to different elements: asset views are provided with uniform shared perspective quality for collaborative efficiency, while avatar representations maintain individual spatial quality for accurate user presence. This local differentiation resolves the productivity-reliability conflict.

AI summary
Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures include: rendering, to a display device of a first user, a first user's view into an extended reality environment, the first user's view being generated using a first pose being tracked for the first user; identifying that a first avatar associated with the first user has entered a shared perspective mode with a second avatar associated with a second user of the XR environment, wherein the shared perspective mode has a single frame of reference in the XR environment that is shared by the first user and the second user; and performing, while in the shared perspective mode, the rendering to the display device of the first user.
