VR Bullet Screen Depth Layering for Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Virtual Reality (VR) systems, the limited display size and depth perception of traditional screens hinder the readability of bullet screens, which are real-time comments that fly across the screen like bullets, especially when multiple comments are displayed simultaneously.
Innovation Solution
A method and apparatus for displaying bullet screens in a VR device by rendering a virtual three-dimensional space scene, where bullet screens are positioned at different depths within the scene, allowing for enhanced readability and user experience through strategic placement and display rules such as varying font sizes and contrast ratios based on the user's view angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple bullet screens are displayed simultaneously on a traditional screen, then the quantity of information is increased, but the readability is deteriorated due to limited display size
Solution Approach 1:
The patent transitions from traditional 2D screen display to 3D virtual space display for bullet screens. By positioning bullet screens at different depth coordinates (z-axis) in addition to horizontal (x-axis) and vertical (y-axis) positions, the system creates multiple display layers that can be simultaneously viewed without overlapping, thereby increasing the quantity of readable bullet screens while maintaining readability through spatial separation.
2Quantity of substance
If more bullet screens are displayed, then the information quantity increases, but the user experience deteriorates due to overlapping and reduced clarity
Solution Approach 1:
The patent segments the display space into multiple depth layers along the z-axis. Bullet screens are assigned to different layers based on their position parameters, allowing simultaneous display of multiple comments without overlap. This segmentation enables users to clearly distinguish between different bullet screens while viewing multiple comments, thereby improving user experience.
Solution Approach 2:
By introducing the depth dimension (z-coordinate) to the traditional 2D display, the system allows bullet screens to be positioned at different depths within the virtual scene. This dimensional expansion enables simultaneous display of multiple bullet screens without visual overlap, directly improving user experience while increasing information quantity.
3Device complexity
If traditional 2D display is used, then the device complexity is low, but the display function versatility is limited
Solution Approach 1:
The patent extends the display system from 2D to 3D virtual space by introducing depth positioning. Bullet screens are rendered with z-coordinate values that place them at different distances from the viewer, creating a multi-layered display effect. This dimensional enhancement provides versatile display functions including depth-based sorting, layered composition, and spatial arrangement, while the underlying rendering engine handles the complexity.
