XR Content Navigation for Shared Field-of-View Collaboration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In extended reality (XR) environments, coordinating a common field of view (FOV) among multiple users viewing a virtual reality (VR) object is challenging due to independent control over FOVs, making it difficult for participants to align their views on a specific area of interest.
Innovation Solution
A VR content navigation platform dynamically controls a shared FOV among XR systems by identifying a VR object and respective FOVs, generating potential collaboration combinations using a collaboration engine, and instructing XR systems to present a shared view, which can be dynamically controlled by one user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each participant has independent control over their field of view in the VR environment, then each participant can view different areas of interest freely, but it becomes difficult to coordinate a common viewing direction among multiple participants
Solution Approach 1:
The patent introduces a central server as an intermediary that receives FOV data from multiple XR devices, determines a common area of interest, and distributes navigation commands back to the devices. This mediator coordinates the independent FOV controls by providing a shared reference point (common area of interest) that all participants can navigate to simultaneously, resolving the contradiction between individual freedom and group coordination.
Solution Approach 2:
The system implements a feedback loop where each XR device continuously transmits its current FOV information to the server, which then calculates the common area of interest and sends navigation instructions back to the devices. This closed-loop feedback mechanism enables dynamic coordination of viewing directions while preserving independent control, as each device adjusts its FOV based on real-time feedback from the coordination system.
2Productivity
If multiple users are physically located in different places, then collaboration can occur remotely without assembly at a common location, but coordinating their views on the same VR object becomes challenging
Solution Approach 1:
The server implements a universal coordination mechanism that handles multiple XR devices simultaneously, determining a single common area of interest that serves all participants regardless of their physical locations. This multi-functional approach allows the system to manage remote collaboration for any number of users with a single coordination framework, enabling remote work while managing the complexity of coordinating diverse device FOVs.
3Reliability
If one participant wants to share their viewing direction with other participants, then collaboration on specific problem areas is enhanced, but the independent nature of each XR device makes this coordination difficult
Solution Approach 1:
The server acts as a mediator that receives FOV information from the initiating participant, determines the common area of interest, and distributes navigation commands to all participants. This intermediary approach ensures accurate view alignment by centralizing the coordination logic, while the distributed architecture keeps individual device complexity manageable by handling the coordination burden on the server side.
