World-locked Volumetric Object Display in VR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in effectively displaying volumetric visual content, particularly in augmented and virtual reality, due to issues with non-viewable regions in world-locked volumetric objects, such as missing or insufficient static and animated display data, which can limit user interaction and immersion.
Innovation Solution
An apparatus and method that determine changes in a user's viewing position relative to world-locked volumetric objects, causing them to be user-locked if a non-viewable region is about to be displayed, ensuring seamless display and animation by accessing metadata and synthesizing information to manage display data and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If world-locked volumetric objects are displayed with incomplete data (missing static and/or animated display data), then device complexity is reduced and productivity is improved, but manufacturing precision and reliability deteriorate due to non-viewable regions
Solution Approach 1:
The system performs preliminary actions by detecting potential non-viewable regions before they are displayed, and proactively switching the volumetric object from world-locked to user-locked mode in advance. This prevents the display of incomplete data while maintaining smooth operation without waiting for actual viewing position changes.
Solution Approach 2:
The system continuously monitors the user's viewing position relative to the volumetric object and provides feedback by detecting when non-viewable regions are about to be displayed. This feedback loop enables dynamic switching between world-locked and user-locked modes based on real-time viewing conditions.
2Reliability
If the system switches from world-locked to user-locked mode to prevent non-viewable regions, then reliability is improved, but device complexity increases due to additional mode switching logic
Solution Approach 1:
The patent extracts the problematic non-viewable region detection and mode switching logic as a separate, independent module that operates independently from the core volumetric object rendering system. This modular approach manages complexity by isolating the switching mechanism while maintaining reliability.
3Adaptability or versatility
If animations are displayed from non-viewable regions, then adaptability is improved, but object-generated harmful factors increase due to potential display errors
Solution Approach 1:
The system applies preliminary anti-action by detecting potential display errors in animated regions before they occur. When non-viewable animated regions are detected, the system proactively switches to user-locked mode to prevent the harmful display errors from occurring in the first place.
