XR Spatial Mapping and Content Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current extended reality technologies lack the ability to seamlessly integrate pre-generated content with real-time interaction and synchronization across devices, resulting in a suboptimal user experience for augmented and mixed reality environments.
Innovation Solution
The method involves mapping a virtual space to a physical space using extended reality devices, receiving pre-generated content, and synchronizing it with content item playback, allowing for concurrent output of augmented reality content that adapts to user interactions and time stamps, while ensuring that virtual objects do not obstruct the physical display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual objects are added to enhance XR content, then user engagement and immersion are improved, but virtual objects may obstruct the view of the physical display
Solution Approach 1:
The system applies different spatial rules to different regions of the display space. Virtual objects are constrained to specific zones (off-screen or peripheral areas) while the central viewing area remains clear, allowing local optimization where engagement is enhanced without compromising the primary viewing experience
Solution Approach 2:
The patent moves virtual objects from the two-dimensional display plane into the third spatial dimension by positioning them in off-screen or peripheral spatial zones. This dimensional transition allows virtual objects to coexist with display content without blocking the view, as they occupy different spatial layers rather than competing for the same visual space
2Adaptability or versatility
If pre-generated XR content is synchronized with content item playback, then immersion is improved, but synchronization complexity across devices increases
Solution Approach 1:
The system performs preliminary actions by pre-generating XR content and preparing synchronization data before playback begins. Timestamps and spatial mapping information are pre-calculated and attached to content segments, enabling seamless synchronization without real-time computation complexity during actual playback
Solution Approach 2:
The patent introduces a media device (such as a set-top box or streaming device) as an intermediary that handles the complex synchronization tasks. This intermediary translates content item playback events into corresponding XR content activation signals, managing the synchronization complexity centrally rather than requiring direct coordination between all devices
3Measurement precision
If virtual space is mapped to physical space, then spatial accuracy is improved, but processing requirements and device complexity increase
Solution Approach 1:
The system performs spatial mapping as a preliminary action during content preparation rather than in real-time during playback. Virtual objects are pre-positioned and spatial relationships are pre-calculated based on the physical display environment, reducing processing requirements during actual XR content delivery while maintaining spatial accuracy

AI summary
Systems and methods are provided for enabling an enhanced extended reality experience. A virtual space is mapped to a physical space at an extended reality device, and pre-generated extended reality content, for display with a content item, is received at the extended reality device. It is identified that the content item has started playback at a display, and the content item and the extended reality content are generated for concurrent output at the extended reality device.
