Dynamic Function Input Unit for High-Speed Page Scrolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems are inefficient in quickly scrolling to the top end of a page, especially when the scroll operation is performed at a high speed, as they do not adapt the user interface effectively to enhance user convenience and scrolling speed.
Innovation Solution
The system introduces a second function input unit that replaces the first function input unit when a scroll operation exceeds a threshold speed, allowing quicker movement to the top end of the page, and dynamically changes back to the first function input unit when the scroll operation stops, providing visual effects and improved user interface experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the first function input unit is displayed during high-speed scrolling, then the user interface remains consistent, but the user cannot quickly navigate to the top end of the page
Solution Approach 1:
The patent applies dynamics by making the function input unit change based on scrolling speed. When scrolling exceeds a threshold speed, the interface switches from the first function input unit to the second function input unit, allowing quick navigation to the top end of the page. This dynamic adaptation resolves the contradiction by providing different interface configurations for different operating conditions.
2Adaptability or versatility
If the interface adapts during scrolling, then user convenience is improved, but the system complexity increases
Solution Approach 1:
The patent uses parameter changes by monitoring scrolling speed as a parameter and switching between different function input units based on whether the speed exceeds a threshold. This approach provides interface adaptability through a relatively simple mechanism that only requires speed detection and conditional display switching, avoiding excessive system complexity.

AI summary
A method for controlling a terminal screen includes: first displaying, on a screen of a terminal, a first function input unit and at least a portion of a page of content on a screen, the first function input unit being associated with at least a first function for the terminal; recognizing a scroll operation on the screen; and second displaying, in response to the recognizing the scroll operation on the screen, a second function input unit instead of at least a portion of the first function input unit, the second function input unit being associated with a second function for the terminal.
