Scrolling Image Display Control with End-of-Range Visual Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interfaces for scrolling images often fail to intuitively indicate when the end of a display area has been reached, leading to confusion between the end of scrolling and potential device failure.
Innovation Solution
An information processing device with a scrolling unit, display control unit, and propagating unit that changes the appearance of images when the end of a display area is reached, propagating this change within the image group to inform users that scrolling has stopped.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional scrolling interface is used, then device complexity is reduced, but user recognition of display area end becomes unclear
Solution Approach 1:
The patent applies color changes to images at the end of the display area to indicate when scrolling has reached its limit. Specifically, when the scrolling image group reaches the end position, the system changes the color of the terminal image (the image at the scrolling direction's end) to a predetermined color different from normal display colors. This visual feedback mechanism provides clear user recognition of the display area end without adding complex hardware or interface elements.
Solution Approach 2:
The patent implements dynamic visual feedback by propagating the color change effect from the terminal image to other images in the scrolling group. When the terminal image changes color, this color change propagates to adjacent images in sequence, creating a dynamic wave-like visual effect that clearly indicates the scrolling has reached its end. This dynamic approach enhances user recognition while maintaining interface simplicity.
2Loss of information
If visual feedback is added to indicate scrolling end, then user recognition is improved, but interface complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the system monitors the scrolling position and provides visual feedback when the end of the display area is reached. The display control unit detects when the scrolling image group reaches the end position and automatically triggers the color change of the terminal image. This feedback loop provides continuous information about scrolling position and status without requiring complex user input or additional hardware sensors.
Solution Approach 2:
The system performs self-service by automatically detecting the scrolling end position and initiating the visual feedback mechanism without external intervention. The display control unit continuously monitors the scrolling state and autonomously determines when to apply the color change effect, eliminating the need for additional control hardware or complex user interactions to indicate scrolling status.

AI summary
An exemplary information processing device includes: a scrolling unit configured to scroll an image group including plural images, in accordance with an input from a user; a display control unit configured to change how at least one image included in the image group is displayed, upon the image group reaching a predetermined end as a result of scrolling; and a propagating unit configured to propagate the change from one image included in the image group to another image included therein.
