XR Avatar Spatial Modes for Consistent Multiuser Presence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extended reality (XR) environments struggle with inconsistent representations of multiuser communication sessions, leading to spatial relationship discrepancies between local and remote users, which disrupt interactions and context for remote users.
Innovation Solution
The system allows users to select display modes (room scale or stationary) and retarget attention cues to maintain consistent spatial relationships between local and remote users, using modules like XR module 165 and presentation module 170 to manage XR environments and adjust virtual object presentations based on user interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If XR environments allow multiple users to interact within the same environment, then collaboration and communication are enhanced, but spatial relationship inconsistencies between local and remote users disrupt interaction clarity
Solution Approach 1:
The system changes the parameter of spatial relationship representation by introducing display mode selections (room scale mode vs. stationary mode) that transform how remote users are represented in the XR environment. This allows consistent spatial relationships to be maintained despite differences in user positions and device orientations, resolving the contradiction between multiuser interaction capability and spatial consistency.
Solution Approach 2:
The system dynamically adjusts the representation of remote users based on real-time detection of user actions, attention directions, and spatial relationships. The presentation module dynamically retargets attention cues and adjusts avatar positions to maintain consistent spatial relationships, enabling reliable interaction across different XR environments.
2Reliability
If the system retargets attention cues to maintain consistent spatial relationships, then interaction clarity is improved, but system complexity increases
Solution Approach 1:
The system introduces an intermediary layer in the form of a presentation module that mediates between the raw XR environment data and the final visual representation. This intermediary layer handles the complex retargeting of attention cues and spatial relationship adjustments, managing system complexity through modular architecture while maintaining reliable spatial consistency.
Solution Approach 2:
The system implements feedback mechanisms where the presentation module continuously monitors user actions, attention directions, and spatial relationships, then adjusts representations accordingly. This feedback loop maintains spatial consistency automatically, reducing the need for complex manual configuration and managing system complexity through automated adaptation.
3Adaptability or versatility
If the system provides multiple display modes (room scale or stationary), then user adaptability is improved, but configuration complexity increases
Solution Approach 1:
The system enables self-service configuration by allowing users to select their preferred display mode (room scale or stationary) without requiring complex setup procedures. The presentation module automatically applies the selected mode and adjusts representations accordingly, making the system easy to operate while maintaining high adaptability through multiple display options.

AI summary
Avatars may be displayed in a multiuser communication session using various spatial modes. One technique for presenting avatars includes presenting avatars such that an attention direction of the avatar is retargeted to match the intent of the remote user corresponding to the avatar. Another technique for presenting avatars includes a pinned mode in which a spatial relationship between one or more avatars remains displayed in a consistent spatial relationship to a local user regardless of movements of the local user. Another technique for presenting avatars includes providing user-selectable presentation modes between a room scale mode and a stationary mode for presenting a representation of a multiuser communication session.
