Monoscopic View Convergence Control for VR Object Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inserting 2D objects into 3D virtual reality environments disrupts the user's immersive experience due to changes in convergence distance and potential interpenetration with existing 3D geometry, causing discomfort and visual disconnection.
Innovation Solution
Transforming the stereoscopic view into a monoscopic view with controlled convergence, allowing 2D or 3D objects to be placed at a consistent depth and direction, ensuring all objects appear at the same convergence distance, using techniques like shear transformation and image shifting to maintain user comfort and prevent interpenetration.

Engineering Contradiction Analysis
1Ease of operation
If a 2D GUI object is inserted into a 3D VR environment, then the user interface functionality is improved, but the user's immersive experience deteriorates due to convergence distance changes
Solution Approach 1:
The patent introduces a mediator mechanism that converts 3D VR rendering to 2D rendering temporarily when GUI objects need to be displayed. This intermediary conversion allows the GUI to be rendered without forcing eye convergence changes, thus maintaining immersive experience while preserving UI functionality. The system switches between 3D and 2D rendering modes based on whether GUI objects are present.
2Ease of operation
If a 2D GUI object is inserted into a 3D environment, then the user interface is enhanced, but visual disconnection and interpenetration with 3D geometry occur
Solution Approach 1:
The patent uses 2D rendering as an intermediary approach to prevent interpenetration issues. By converting the VR view to 2D when GUI objects are present, the system eliminates depth information that would otherwise cause GUI objects to visually interpenetrate with 3D geometry. This ensures visual consistency and prevents disconnection artifacts.
Solution Approach 2:
The patent applies dimensionality change by switching from 3D stereoscopic rendering to 2D monoscopic rendering when GUI objects need to be displayed. This dimensional transition resolves the conflict between 2D GUI objects and 3D environment by temporarily removing the depth dimension, preventing interpenetration and visual disconnection while maintaining UI functionality.
3Object-affected harmful factors
If stereoscopic rendering is used to maintain immersive experience, then depth perception is improved, but inserting 2D objects becomes problematic
Solution Approach 1:
The patent implements a dynamic rendering system that automatically switches between stereoscopic 3D rendering and 2D rendering based on the presence of GUI objects. When no GUI objects are present, stereoscopic rendering maintains depth perception and immersive experience. When GUI objects need to be inserted, the system dynamically transitions to 2D rendering to accommodate them properly, then switches back when they are removed.
Solution Approach 2:
The patent creates a universal rendering system that can handle both immersive 3D VR content and 2D GUI objects by implementing multiple rendering modes within a single system. The system universally supports both stereoscopic and monoscopic rendering, automatically selecting the appropriate mode based on the current display requirements, thus achieving multi-functionality.
