Multi-User XR Content Adaptation via RF Relative Position Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing extended reality (XR) systems lack efficient mechanisms to modify XR content based on the relative position and orientation of multiple XR devices, leading to inconsistent and uncoordinated user experiences across different devices.
Innovation Solution
The system modifies XR content by determining relative-position information between XR devices using radio-frequency signals, allowing devices to coordinate and synchronize content display based on the position and orientation of other devices, ensuring consistent and coordinated XR experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If XR systems display common virtual content to multiple users without modification, then content delivery is simple and fast, but user experience consistency deteriorates when users are in different relative positions
Solution Approach 1:
The system dynamically modifies XR content based on real-time relative position information between XR devices. The content modification is not static but adapts continuously as users move, ensuring that each user sees appropriate content variations based on their spatial relationship with other users. This resolves the contradiction by making the content delivery system flexible and responsive to changing spatial conditions.
Solution Approach 2:
The system uses RF signal measurements to continuously feedback relative position information between XR devices. This feedback loop enables the system to automatically adjust content display based on measured spatial relationships, improving user experience consistency without requiring complex manual configuration. The feedback mechanism allows the system to self-regulate content delivery based on actual spatial conditions.
2Reliability
If XR systems modify content based on precise relative position measurements, then user experience coordination improves, but system complexity and measurement requirements increase
Solution Approach 1:
The system uses RF signals as an intermediary to indirectly determine relative position between XR devices. Rather than requiring complex direct measurement mechanisms between devices, the RF signal acts as a mediator that carries spatial information. This approach improves content coordination accuracy while avoiding the need for overly complex direct measurement systems.
Solution Approach 2:
The system replaces complex mechanical or optical measurement systems with RF-based electronic measurement. By using radio frequency signals to determine relative position, the system achieves accurate spatial awareness without requiring complex mechanical sensors or optical tracking systems, thus improving coordination accuracy while managing system complexity.
3Ease of operation
If XR systems continuously track and modify content based on real-time device positions, then user interaction quality improves, but energy consumption increases
Solution Approach 1:
The system performs content modification based on periodic RF signal measurements rather than continuous modification. By measuring relative positions at appropriate intervals and modifying content accordingly, the system maintains high-quality user interaction while reducing energy consumption compared to truly continuous tracking and modification. The periodic action allows the system to balance interaction quality with energy efficiency.
