Head-Mounted Display Hand Rendering Before Pose Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Immersive systems like VR, AR, and MR experience delays due to stabilization periods for tracking device position data, leading to diminished user immersion and responsiveness.
Innovation Solution
An immersive system and method that computes an appropriate hand position without initial pose data, rendering a virtual model immediately, and corrects it based on stabilized pose data post-stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system waits for pose data stabilization before rendering the virtual model, then the position accuracy is improved, but the response time deteriorates
Solution Approach 1:
The system performs preliminary rendering of the virtual model using default or estimated position data before the pose data stabilization is complete. This allows the visual content to be displayed immediately while the positioning system continues to stabilize, eliminating the waiting period while maintaining acceptable positional accuracy through subsequent corrections.
2Loss of time
If the system renders the virtual model immediately without waiting for pose data stabilization, then the response time is improved, but the position accuracy deteriorates
Solution Approach 1:
The system implements a feedback mechanism where the virtual model's position is continuously adjusted based on the stabilized pose data once it becomes available. The initial rendering uses approximate positioning, and subsequent corrections refine the position accuracy, creating a closed-loop system that improves precision over time while maintaining immediate responsiveness.
3Manufacturing precision
If the system uses stabilized pose data for rendering, then the rendering accuracy is improved, but the user immersion deteriorates due to waiting
Solution Approach 1:
The system renders the virtual model immediately using preliminary positioning data, allowing users to interact with the immersive environment without waiting for stabilization. The rendering accuracy is then progressively improved as stabilized pose data becomes available, maintaining both user immersion and eventual precision.
4Manufacturing precision
If the system delays rendering until pose data is stabilized, then the rendering accuracy is improved, but the productivity deteriorates
Solution Approach 1:
The system maintains continuous rendering operations without interruption by using available positioning data immediately. The rendering process continues uninterrupted while the positioning system stabilizes in the background, with accuracy improvements applied progressively, ensuring both high productivity and acceptable rendering quality throughout the stabilization period.
