Dynamic Scroll Speed Control for Content Lists
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices lack the ability to dynamically adjust the scroll speed and shape of content lists based on the importance of individual contents, leading to uniform display speeds and shapes regardless of content features.
Innovation Solution
The method involves determining the importance of contents using weights based on factors like time, preference, location, and tag information, and adjusting the scroll speed and shape by decreasing the speed for important contents and restoring it when they are no longer displayed, while also modifying the display shape by enlarging or shrinking important content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device displays the content list at the same speed irrespective of content features, then the display is simple and uniform, but the user cannot easily identify important content
Solution Approach 1:
The patent applies dynamics by making the scroll speed variable rather than fixed. The scrolling system dynamically adjusts speed based on content importance weights, transitioning from a static uniform display to a dynamic adaptive display that responds to content characteristics.
Solution Approach 2:
The patent implements local quality by applying different scroll speeds to different portions of the content list based on their individual importance weights. Instead of uniform treatment, each content item receives differentiated display treatment according to its specific characteristics.
2Ease of operation
If the electronic device displays all contents in the same shape, then the display is consistent and simple, but the user cannot distinguish important content from other contents
Solution Approach 1:
The patent applies local quality by giving different display shapes to different content items based on their importance. Important content items are displayed with enlarged shapes while less important items maintain standard sizes, creating visual differentiation.
Solution Approach 2:
The patent implements asymmetry by breaking the uniform display shape convention. Instead of all content items having identical shapes, the system creates asymmetric display shapes where important content is visually distinguished through size variations.
3Productivity
If the electronic device scrolls through the content list at high speed, then productivity is high, but the user may miss important content
Solution Approach 1:
The patent uses dynamics to adjust scroll speed in real-time based on content importance. The system transitions from a fixed high-speed scroll to a dynamic scroll that slows down automatically when important content is detected, ensuring visibility while maintaining overall productivity.
Solution Approach 2:
The patent implements feedback by continuously monitoring content importance weights during scrolling and using this information to adjust scroll speed. The system receives feedback about content characteristics and responds by modifying scrolling behavior accordingly.
