Multi-Layer Bullet-Screen Comment Display for 3D Spatial Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video bullet-screen comments lack a 3D spatial effect, limiting user experience due to their single-layer and horizontal or vertical movement.
Innovation Solution
Implement a method to display bullet-screen comments at multiple layers with varying angles, speeds, transparency, and font sizes, ensuring they do not overlap and creating a 3D spatial effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If bullet-screen comments are displayed in a single layer with horizontal or vertical movement, then the implementation is simple, but the 3D spatial effect is lacking and user experience is limited
Solution Approach 1:
The patent applies dimensionality change by transitioning from single-layer 2D bullet-screen comments to multi-layer 3D spatial arrangement. Comments are distributed across multiple layers with different Z-axis positions, creating depth perception and spatial层次感 (layered structure). This resolves the contradiction by adding spatial dimensions while maintaining implementation feasibility through systematic layer management.
Solution Approach 2:
The patent segments the bullet-screen comment display into multiple independent layers, where each layer can be managed and rendered separately. This segmentation enables the complex 3D spatial effect to be achieved through composition of simpler layer elements, resolving the contradiction between complexity and spatial effect by breaking down the overall system into manageable segments.
2Adaptability or versatility
If bullet-screen comments are arranged in multiple layers with varying parameters, then the 3D spatial effect is enhanced, but the calculation complexity for track width and coordinates increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing track width and coordinate information for each layer before actual comment display. The system determines layer parameters, track configurations, and spatial relationships in advance, which simplifies the real-time display process. This resolves the contradiction by shifting computational complexity to a preliminary setup phase rather than real-time operation.
Solution Approach 2:
The patent utilizes parameter changes by systematically varying display parameters (such as track width, coordinates, transparency, and positioning) across different layers to create the 3D spatial effect. By establishing clear parameter relationships and calculation rules for each layer, the system manages complexity through structured parameter management while achieving rich spatial visualization.
3Adaptability or versatility
If bullet-screen comments move at different angles and speeds, then the visual dynamics are enriched, but the control and coordination become more difficult
Solution Approach 1:
The patent applies dynamics by enabling bullet-screen comments to have variable motion characteristics including different angles, speeds, and directions across multiple layers. Each comment can be configured with dynamic motion parameters that allow for rich visual effects while maintaining controllability through a unified management system that coordinates all moving elements.

AI summary
A bullet-screen comment display method is provided. The method includes: obtaining a to-be-displayed bullet-screen comment; placing the to-be-displayed bullet-screen comment into a target bullet-screen comment track at a target bullet-screen comment layer when the to-be-displayed bullet-screen comment meets a preset placement condition, where the target bullet-screen comment layer is one of several bullet-screen comment layers, and the target bullet-screen comment track is one of bullet-screen comment tracks at the target bullet-screen comment layer; and displaying the to-be-displayed bullet-screen comment in the target bullet-screen comment track based on a bullet-screen comment configuration, where the bullet-screen comment configuration includes at least a preset angle between a moving direction of the to-be-displayed bullet-screen comment and a horizontal direction or a vertical direction.
