Hybrid Cross-Reality Collaboration via Spatial Bubbles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in enhancing group awareness and enabling fluid collaboration between users of extended reality (XR) devices and those without XR devices, leading to isolation and difficulty in understanding each other's content.
Innovation Solution
A system that utilizes a common display to receive content from multiple user devices, including XR devices, and displays it in separate bubbles, merging or separating them based on user proximity, with spatial awareness and access control, allowing content sharing and editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If XR users collaborate with non-XR users using traditional display methods, then information exchange occurs, but group awareness is reduced and collaboration fluidity is impaired
Solution Approach 1:
The display is segmented into multiple spatial zones or bubbles, each representing different users or user groups. This segmentation allows simultaneous presentation of multiple perspectives without overwhelming any single user, thereby maintaining group awareness while enabling focused interaction within each segment.
Solution Approach 2:
The system transitions from traditional two-dimensional flat display to a three-dimensional spatial display architecture. By arranging content in depth layers and spatial positions, multiple users can view and interact with different portions of the display simultaneously, enhancing group awareness without compromising collaboration fluidity.
2Reliability
If XR users are isolated in their virtual environment, then their immersive experience is maintained, but understanding from non-XR users becomes difficult
Solution Approach 1:
The system introduces an intermediary layer that translates and represents XR content in forms accessible to non-XR users. This intermediary representation maintains the integrity of the original XR experience while providing comprehensible visualizations for external users, thus preserving immersion while improving understandability.
Solution Approach 2:
The system employs visual encoding techniques including color coding, transparency variations, and highlight effects to differentiate between XR and non-XR user perspectives. These visual changes help non-XR users understand the nature and state of XR content without breaking the XR user's immersive experience.
3Productivity
If multiple users share a common display simultaneously, then collaboration is enabled, but cognitive load increases and isolation occurs
Solution Approach 1:
The display configuration is made dynamic, automatically adjusting the number, size, and position of visible content segments based on the number of users present and their relative positions. This dynamic adaptation optimizes the display for current collaboration needs, enabling multi-user productivity while managing cognitive load through context-aware interface adjustments.

AI summary
A method may include: receiving, by a computer program executed by an electronic device, first content from a first user electronic device for a first user; receiving, by the computer program, second content from a second user electronic device for a second user; displaying, by the computer program, the first content on a common display in a first bubble, and the second content on the common display in a second bubble; receiving, by the computer program and from a sensor, a first location of the first user near the common display and a second location of the second user near the common display; and displaying, by the computer program, the first bubble and the second bubble on the common display based on the first location and the second location, respectively.
