Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current live video streaming technologies lack effective methods for enhancing user interaction with bullet-screen comments, which often result in poor display and interaction effects, leading to a suboptimal user experience.
Innovation Solution
A method and system for image bullet-screen comment interaction that involves selecting and rotating cards to a target direction, determining their motion tracks based on previous cards, and displaying animation effects upon user input, allowing for varied card shapes, sizes, and animation effects like fireworks or falling stars, to improve engagement and avoid overlapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional bullet-screen comments are displayed horizontally without rotation, then the display is simple and easy to implement, but the visual appeal and user engagement are poor
Solution Approach 1:
The patent applies dynamics by rotating bullet-screen comments from static horizontal display to dynamic angled display (45 degrees). The comments are rotated and fall along motion tracks from top to bottom, creating a dynamic visual effect that enhances appeal while maintaining manageable complexity through predefined rotation angles and motion patterns.
Solution Approach 2:
The patent transitions from traditional horizontal 2D display to an angled 3D-like falling motion. Comments are rotated 45 degrees and move along diagonal trajectories, adding a new dimensional aspect to the display that improves visual appeal without significantly increasing implementation complexity.
2Quantity of substance
If multiple bullet-screen comments are displayed simultaneously, then the information richness increases, but card overlapping occurs and reduces readability
Solution Approach 1:
The patent segments the display space by assigning each comment card its own unique motion track. Comments are distributed across multiple parallel trajectories, ensuring they do not overlap. This segmentation allows multiple comments to be displayed simultaneously while maintaining readability and visual clarity.
Solution Approach 2:
By introducing diagonal motion tracks at 45-degree angles, the patent adds a temporal and spatial dimension to comment display. Comments move along distinct diagonal paths rather than overlapping horizontal lines, enabling higher comment density without sacrificing readability.
3Adaptability or versatility
If interactive animation effects are added upon user input, then user engagement improves, but the system complexity and processing requirements increase
Solution Approach 1:
The patent implements feedback by detecting user click events on comment cards and triggering corresponding animation effects. When a user clicks a comment, the system responds with visual feedback in the form of fireworks or falling star animations, enhancing engagement while keeping the feedback mechanism straightforward and manageable.
Solution Approach 2:
The patent changes visual parameters dynamically based on user interaction. Upon clicking a comment, the system modifies display parameters by launching animation effects with specific visual characteristics (fireworks, falling stars), providing engaging interaction without requiring complex system restructuring.
4Adaptability or versatility
If cards are rotated to a target direction, then visual appeal and interaction effectiveness improve, but the implementation complexity increases
Solution Approach 1:
The patent applies a fixed rotation angle of 45 degrees to all comment cards, creating a consistent dynamic display pattern. This standardized rotation approach improves interaction effectiveness by making comments more visually engaging while keeping implementation simple through a uniform rotation parameter applied across all cards.

AI summary
The present application provides techniques for displaying and interacting with comments. The techniques comprise selecting a card to be displayed on a display interface from a card pool according to a preset rule; rotating the card to a target direction to obtain a target card; determining a motion track of the target card based on a motion track of a previous target card that enters the display interface immediately prior to the target card; displaying a comment on the display interface using one of a plurality of target cards, the plurality of target cards configured to move on the display interface based on a motion track corresponding to each of the plurality of target cards; and displaying an animation effect associated with a target card among the plurality of target cards in response to determining that the target card among the plurality of target cards is triggered.
