Shared 3D Asset Perspectives With Offset Avatars for XR Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR and XR environments often limit collaborative work by providing discrete viewpoints to users, leading to unequal viewing positions and restricted interaction, especially when multiple users need to share the same perspective on assets.
Innovation Solution
Implementing a shared perspective viewing mode in XR environments where assets are rotated to match the frame of reference of each user, while avatars are repositioned to maintain a spatial relationship, allowing all users to see the same content from the same direction with offset avatars representing their individual perspectives.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If discrete viewpoints are provided to each user in VR/XR environments, then individual user perspectives are maintained, but collaborative equality and shared perspective are compromised
Solution Approach 1:
The system segments the viewing experience into two distinct components: the shared asset perspective (identical for all users) and the avatar representation (individual to each user). This allows each user to maintain their unique spatial position and avatar viewpoint while simultaneously experiencing the same perspective of the shared content, resolving the contradiction between individual perspective maintenance and collaborative equality.
Solution Approach 2:
The patent introduces an additional dimensional layer to the VR/XR experience by separating the content viewing dimension from the user interaction dimension. Users view the shared asset from an identical perspective in one dimension while maintaining their individual avatar positions and perspectives in another dimension, enabling both shared perspective and individual adaptability simultaneously.
2Stability of the object's composition
If users are positioned at different locations in XR environment, then spatial relationships are maintained, but shared perspective viewing is limited
Solution Approach 1:
The system divides the viewing experience into segmented components: the shared asset is rendered from a unified perspective that all users access equally, while user avatars maintain their individual spatial positions and relationships. This segmentation allows spatial relationships to remain stable while shared perspective capability becomes adaptable to multiple user positions simultaneously.
Solution Approach 2:
The shared asset perspective acts as an intermediary between users at different spatial locations. Rather than requiring users to physically occupy the same position, the system provides a mediated viewing experience where all users observe the asset from the same perspective while their avatars maintain their distinct spatial relationships in the virtual environment.
3Ease of operation
If avatars are positioned at the same location for shared viewing, then perspective equality is achieved, but spatial interaction clarity is reduced
Solution Approach 1:
The patent segments the representation system into two independent elements: the shared asset perspective (positioned at the same location for all users to ensure equality) and the user avatars (positioned at their individual locations to preserve spatial relationship information). This segmentation eliminates the need to choose between perspective equality and spatial clarity, as both can be simultaneously optimized.

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.
