Popping-Screen Display in VR Using 3D Spatial Scene Templates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current popping-screen technologies only offer a single type of viewing experience, failing to meet user demands for diversity and variety in displaying comments during network video broadcasting.
Innovation Solution
A method and system that utilize a client terminal and server in communication, with an application tool for virtual reality playback, allowing users to select from multiple 3D spatial scene templates and display user comments as popping-screens, integrating virtual reality videos with diverse 3D spatial scenes and light source data to provide a multi-dimensional viewing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single type of popping-screen display is used, then the system is simple to operate, but the user experience lacks diversity and variety
Solution Approach 1:
The system dynamically switches between different 3D spatial scene templates based on user selection, allowing the popping-screen display to adapt its spatial characteristics, movement patterns, and visual presentation. This enables diverse viewing experiences while maintaining a unified system architecture that manages multiple templates through a centralized control mechanism.
Solution Approach 2:
The patent implements multiple 3D spatial scene templates with different parameters including spatial distribution patterns, movement speeds, display densities, and visual effects. By changing these parameters across different templates, the system provides diverse popping-screen experiences without requiring fundamentally different system structures, thus balancing versatility with manageable complexity.
2Adaptability or versatility
If multiple 3D spatial scene templates are introduced, then user viewing experience diversity is improved, but the processing and rendering load increases
Solution Approach 1:
The system pre-processes and pre-renders multiple 3D spatial scene templates in advance, storing them as ready-to-use configurations. When a user selects a template, the pre-processed data is quickly loaded and applied without requiring intensive real-time computation, thus reducing the processing load during actual video playback while still providing diverse viewing options.
Solution Approach 2:
The patent divides the complex rendering task into separate, independent 3D spatial scene templates. Each template is self-contained with its own spatial parameters, movement patterns, and visual characteristics. This segmentation allows the system to process and render only the selected template's data during playback, distributing the computational load across multiple independent modules rather than requiring simultaneous processing of all templates.
3Manufacturing precision
If 3D rendering technology and scene chartlets are used, then the visual quality and immersion are enhanced, but the manufacturing and implementation complexity increases
Solution Approach 1:
The patent uses scene chartlets as simplified graphical representations that capture the essential spatial and visual characteristics of complex 3D scenes. These chartlets serve as templates or copies that can be quickly instantiated and rendered, providing high visual quality through 3D rendering technology while reducing implementation complexity by using pre-designed, reusable scene templates rather than creating custom 3D environments from scratch.

AI summary
Techniques for displaying popping-screen comment information in a virtual reality environment are described herein. The disclosed techniques include retrieving popping-screen comment information associated with a video in response to a request for displaying the popping-screen comment information while playing the video; acquiring a corresponding type of 3D spatial scene template in response to a request for a display type; integrating the popping-screen comment information into the first corresponding type of 3D spatial scene template and the video; and displaying the comment information in a virtual reality environment by combining the popping-screen information with a picture captured by a primary-viewing-angle virtual camera, a plurality of pictures captured by a plurality of auxiliary-site virtual cameras, and a scene chartlet.
