Mobile Terminal Scrolling Visual Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals do not visually indicate to users when they have reached the last region of an image during scrolling, leading to user inconvenience and repetitive touch inputs.
Innovation Solution
A scrolling method for mobile terminals that modifies and restores at least some region of the first image portion on the display when the last region is reached, providing visual feedback to the user through changes in image size or gaps, indicating that further scrolling is impossible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal does not scroll the image when the last region is reached, then the image display remains stable, but the user experience deteriorates due to lack of visual feedback and repetitive touch inputs
Solution Approach 1:
The patent applies feedback by modifying the display of the first image portion when the last region is reached during scrolling. This creates visual feedback (through modification and restoration of the image portion) that informs the user they have reached the boundary, eliminating the need for repetitive touch inputs while maintaining display stability.
Solution Approach 2:
The patent utilizes color changes as a visual feedback mechanism. When the last region is reached, the first image portion is modified (which includes color changes) and then restored, providing clear visual indication to the user that scrolling has reached its boundary without causing repetitive inputs.
2Ease of operation
If the mobile terminal provides visual feedback when the last region is reached, then user interaction improves, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent applies partial action by modifying only the first image portion (rather than the entire image) when the last region is reached. This selective modification provides the necessary visual feedback while minimizing processing requirements and avoiding excessive complexity in the scrolling control system.
3Ease of operation
If the first image portion is modified and restored continuously, then visual feedback is provided to users, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by modifying and restoring the first image portion only when specific conditions are met (when the last region is reached during scrolling). This periodic modification rather than continuous modification reduces energy consumption while still providing effective visual feedback at the critical moments when users need information about scrolling boundaries.

AI summary
A scrolling method and apparatus devices having display screens such as a mobile terminal. When a first image on a screen cannot be moved in a direction by a touch input, a region of the first image is modified in response to the touch input and the modified image is subsequently restored to the first image after the touch is released or a preset amount of time passes. The modification of the region of the image provides an indication that is fed back to the user so that the end or last part of the image is displayed and cannot be moved further, so that undesired repetitive touch input can be prevented.
