Shared XR Presentation Control for Multi-Device Content Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality devices struggle to coordinate and present shared content effectively among multiple users due to differing coordinate systems and limited interaction capabilities, while virtual reality devices face challenges in facilitating physical space interactions.
Innovation Solution
A system and method for controlling shared extended reality presentations using a display and processor to manage group associations, content distribution, and status updates among computing devices, including head-mounted displays, through a graphical user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If augmented reality devices are used to present content to multiple users, then users can interact with the physical environment and each other, but different devices may not use the same coordinate system and content may not be presented in correspondence with the same physical space
Solution Approach 1:
The patent introduces a server as an intermediary that receives coordinate system transformation parameters from one device and distributes them to other devices. This mediator enables different AR devices with varying coordinate systems to present content that corresponds to the same physical space, resolving the coordinate alignment issue while preserving interaction capabilities.
2Measurement precision
If virtual reality content is presented to multiple users, then a universal frame of reference can be established, but interaction between users in their physical space is severely limited due to complete immersion
Solution Approach 1:
The patent creates a system that serves multiple functions simultaneously: it maintains a universal frame of reference for consistent content presentation while also enabling physical space interaction through the AR device's camera and display. The system can switch between fully immersive VR mode and augmented reality mode that allows physical interaction, making the system universally applicable to both needs.
3Reliability
If a system coordinates multiple extended reality devices to present shared content, then synchronized content presentation across devices is achieved, but device complexity and coordination requirements increase
Solution Approach 1:
The patent implements a feedback mechanism where devices send status information and coordinate data to the server, which then adjusts content presentation parameters to maintain synchronization. This feedback loop ensures reliable synchronized content presentation across multiple devices while automating the coordination process to reduce manual complexity.
