Mobile Scroll Speed Control via Periodic Screen Stops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed scrolling on mobile terminals results in invisible content details due to restricted performance, making it difficult for users to view content while scrolling multiple pages, and the continuous movement of the scrollbar hampers smooth scrolling.
Innovation Solution
A method and system that distinguish high-speed scrolls from general scrolls by slowing down the scroll speed during flicking, stopping the screen for a predetermined time, and then resuming, allowing users to recognize content before moving to the next screen, while also hiding and re-outputting the scrollbar at appropriate times to reduce load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the screen is scrolled at a high speed using flicking method, then the scrolling speed is improved, but the content details become invisible and unreadable during scrolling
Solution Approach 1:
The patent implements periodic action by repeatedly stopping the screen at intervals during high-speed scrolling. The controller pauses the display at multiple positions along the scrolling path, allowing users to read content at each stop. This periodic stopping pattern maintains high overall scrolling speed while ensuring content visibility at regular intervals, directly resolving the contradiction between speed and readability.
2Loss of information
If the scrollbar is continuously displayed and moved during scrolling, then the scrollbar provides position information, but the scroll performance becomes unsmooth on mobile terminals with restricted performance
Solution Approach 1:
The patent extracts the scrollbar from continuous display and only shows it at specific moments - when the screen stops during periodic scrolling. This extraction principle removes the performance burden of continuously rendering and updating the scrollbar while still providing position information at critical pause points, resolving the contradiction between information provision and performance.
3Loss of information
If the screen is stopped for a long time to allow content recognition, then the content readability is improved, but the overall scrolling efficiency decreases
Solution Approach 1:
The patent applies partial action by implementing multiple brief stops rather than one long stop. The screen pauses at several intermediate positions during scrolling, providing sufficient reading time at each point while maintaining overall scrolling momentum. This distributed stopping approach achieves readability without the time loss associated with a single extended pause.

AI summary
A high-speed scroll contents display system includes: a web document providing apparatus, as a user terminal is connected, a web document created in a web description language to the connected user terminal; and the user terminal for receiving the web document from the web document providing apparatus, displaying the web document as a web page screen on a mobile browser, and performing, if movement of a touched state on the web page screen is sensed, a contents scroll in correspondence to a sensed moving direction, repeating an operation of performing a high-speed scroll on contents while reducing a speed according to an ease function in a flicking direction of a sensed flick, stopping movement of the screen for a predetermined time period, and moving again the screen reducing the speed according to the ease function when the predetermined time period is elapsed, until an end of the flick is sensed.
