Dynamic Page Flip Animation Control via Touch Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current page flip animation technologies on terminals do not adapt to user interactions, as play duration and animation speed are fixed, failing to provide a smooth and environment-aware experience regardless of user swipe speed or style.
Innovation Solution
A display control method that dynamically adjusts animation play parameters based on actual touch parameters, such as swipe distance and speed, to create a page flip animation effect consistent with the user's touch scenario, using Bézier curve interpolators and preset relationships to determine play duration and speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed animation play parameters are used for page flip animation, then the animation effect is consistent and simple to implement, but the animation cannot adapt to different user swipe speeds and environments
Solution Approach 1:
The patent applies dynamics by making the animation play parameters dynamic rather than fixed. The system adjusts animation speed and duration based on real-time touch parameters (swipe distance, swipe speed) detected during user interaction. This allows the animation to adapt to different user operations while maintaining implementation feasibility through parameter-based control mechanisms.
Solution Approach 2:
The patent changes physical parameters of the animation system based on touch input characteristics. Specifically, it modifies animation play speed and duration parameters according to swipe distance and swipe speed parameters detected from user touch operations. This parameter adaptation enables the animation to match user interaction intensity without requiring complex structural changes.
2Speed
If animation speed is increased to match fast user swipes, then the animation responds quickly to user operations, but the animation may become too fast for slow swipes and lose smoothness
Solution Approach 1:
The patent implements feedback by continuously monitoring touch parameters (swipe distance, swipe speed) during user interaction and using this information to adjust animation playback characteristics. The system receives feedback from touch events and modifies animation speed accordingly, ensuring the animation matches the user's swipe pace whether fast or slow, thereby maintaining smoothness across different interaction speeds.
3Duration of action of moving object
If the animation play duration is extended to ensure complete page transition, then the page flip is visually complete, but the transition takes longer and reduces responsiveness
Solution Approach 1:
The patent dynamically changes the animation play duration parameter based on touch input characteristics. When users perform fast swipes with large distances, the system reduces animation duration to maintain responsiveness. When users perform slow swipes, the system extends animation duration to ensure visual completeness. This parameter adaptation optimizes the balance between transition completeness and switching efficiency.

AI summary
A method includes displaying, by a terminal, a first screen on a touchscreen, receiving, by the terminal, a page flip operation from a user on the first screen, playing, by the terminal, a first page flip animation for switching from the first screen to a second screen in response to the page flip operation, where animation play parameters of the first page flip animation are related to first touch parameters generated on the touchscreen by a user finger during the page flip operation, and playing, by the terminal after the page flip operation ends, a second page flip animation for switching from the first screen to the second screen until the terminal displays the complete second screen, where animation play parameters of the second page flip animation are related to second touch parameters generated when the user finger leaves the touchscreen.
