Multi-User XR Viewing Filtering for Dizziness Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D imaging technologies face challenges in providing an optimal viewing experience for multiple users, particularly when a dominant user performs rapid movements or extensive image processing, leading to dizzying effects and impaired analysis for secondary users due to immediate and unfiltered rendering of changes.
Innovation Solution
The implementation of predetermined criteria, such as extent and rate of movement, and image processing filters to determine which changes in the dominant user's viewing parameters are shared with secondary users, ensuring an eye-appealing and stable image by filtering out small or rapid movements and adjustments, thereby preventing dizziness and enhancing analysis capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dominant user's viewing parameter changes are immediately shared with secondary users, then the secondary users can see real-time interactions and manipulations, but the secondary users experience dizziness and discomfort due to rapid movements and extensive image processing
Solution Approach 1:
The patent introduces an intermediary filtering system that processes the dominant user's viewing parameter changes before transmitting them to secondary users. This mediator evaluates each change against predetermined criteria (extent of movement, rate of movement, image processing operations) and only transmits changes that meet the thresholds, thereby stabilizing the visual representation for secondary users while still allowing them to observe significant interactions and manipulations
Solution Approach 2:
The patent dynamically adjusts the parameters of viewing parameter sharing by introducing thresholds for extent of movement, rate of movement, and types of image processing operations. These parameter changes create a controlled transmission mechanism that filters out rapid or excessive movements, preventing dizziness while maintaining real-time collaboration capabilities
2Object-generated harmful factors
If all viewing parameter changes are filtered out to prevent dizziness, then secondary users experience stable images, but significant interactions and manipulations by the dominant user are lost
Solution Approach 1:
The patent implements a feedback mechanism where the filtering system continuously monitors the dominant user's viewing parameter changes and compares them against predetermined criteria. This feedback loop ensures that significant interactions and manipulations are identified and transmitted to secondary users, while minor adjustments are filtered out, thereby preventing both dizziness and information loss
Solution Approach 2:
The patent applies partial filtering by establishing thresholds for extent of movement, rate of movement, and image processing operations. Only changes that exceed these thresholds are transmitted to secondary users, creating a balanced approach that prevents dizziness from excessive transmission while ensuring significant interactions are preserved
3Adaptability or versatility
If real-time collaboration is enabled between multiple users, then users can interact and manipulate 3D images together, but the system complexity increases due to multiple rendering streams and synchronization requirements
Solution Approach 1:
The patent segments the rendering system by designating one user as the dominant user whose viewing parameter changes are monitored and filtered, while other users are classified as secondary users who receive filtered changes. This segmentation simplifies the synchronization complexity by creating a clear hierarchy of rendering streams and reducing the computational burden of managing multiple independent rendering paths
