Virtual Screen Geometry for Immersive VR Video Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for displaying extended video content in virtual reality result in a degraded immersive experience due to the need for extensive remastering and the inability to configure content effectively for VR headsets, leading to black or static content in a large portion of the virtual reality display.
Innovation Solution
A computer-implemented method that transforms extended video data by orienting and positioning virtual screens such that tangent lines to auxiliary screens intersect with the center screen at equal angles between 75 to 105 degrees, using geometric parameters like cylindrical or spherical curvatures, and ratios to create an immersive virtual environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If extended video content is displayed in virtual reality using traditional single-screen formatting, then the content can be shown, but a large portion of the virtual reality display remains black or static, degrading the immersive experience
Solution Approach 1:
The patent transforms traditional 2D single-screen video content into a 3D virtual environment by creating virtual screens with specific geometric configurations. Multiple virtual screens (center screen and auxiliary screens) are positioned in three-dimensional space with defined orientations and angles, allowing video content to occupy multiple spatial dimensions and fill the VR display area more effectively.
Solution Approach 2:
The patent divides the virtual display area into multiple separate virtual screens including a center screen and auxiliary screens positioned at different locations and orientations. Each screen can display video content independently, and together they fill the entire VR field of view, eliminating the black or static areas that would result from using a single screen.
2Productivity
If traditional cinematic content is reformatted for VR display, then content availability increases, but the immersive quality diminishes due to improper screen configuration
Solution Approach 1:
The patent changes key geometric parameters of the screen configuration including the angles between auxiliary screens and the center screen (set to specific ranges like 45-90 degrees), the relative positions of screens, and the field of view parameters. These parameter optimizations ensure that reformed content maintains immersive quality while being adaptable to various VR displays.
Solution Approach 2:
The patent creates a universal virtual screen configuration that can accommodate different types of extended video content (center screen content, auxiliary screen content, and combined content) while maintaining consistent geometric relationships. This multi-functional configuration works across different VR headsets and content types, ensuring both adaptability and reliable immersive quality.
3Adaptability or versatility
If auxiliary screens are positioned at extreme angles to maximize immersion, then peripheral view is enhanced, but video content distortion increases
Solution Approach 1:
The patent employs asymmetric positioning of auxiliary screens relative to the center screen, with each auxiliary screen angled at specific optimized values (e.g., 45-90 degrees from the center screen normal). This asymmetric configuration maximizes peripheral view coverage while the precise angle control prevents excessive distortion, balancing immersion and content fidelity.

AI summary
A method for transforming extended video data for display in virtual reality processes digital extended video data for display on a center screen and two auxiliary screens of a real extended video cinema. The method includes accessing, by a computer executing a rendering application, data that defines virtual screens including a center screen and auxiliary screens, wherein tangent lines to each of the auxiliary screens at their respective centers of area intersect with a tangent line to the center screen at its center of area at equal angles in a range of 75 to 105 degrees. The method includes preparing virtual extended video data at least in part by rendering the digital extended video on corresponding ones of the virtual screens; and saving the virtual extended video data in a computer memory. A corresponding playback method and apparatus display the processed data in virtual reality.
