Scrollable Display Layout for Preserving Button Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies fail to maintain visibility of user-operable buttons when scrolling, leading to user confusion and inconvenience.
Innovation Solution
A display device and method that accommodatively displays specific elements, such as buttons, in a secondary area when they are scrolled out of the primary display area, ensuring their visibility through partial or graphic representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen information is scrolled to enable all display content to be viewed, then the display area can show more content, but user-operable buttons displayed to that point are no longer enclosed within the screen area and are no longer displayed
Solution Approach 1:
The display area is segmented into a first area (main scrollable content area) and a second area (fixed status bar area). Buttons that would otherwise be scrolled out of view are specifically preserved and displayed in the second area, separating the scrolling content from the permanently visible operational elements.
Solution Approach 2:
The system preemptively identifies buttons that will be scrolled out of view and relocates them to the second area before the scrolling occurs. This preliminary action ensures that operational elements remain accessible without waiting for the user to notice their disappearance.
2Productivity
If the screen information is scrolled, then more content can be viewed, but the user is unable to recognize the presence of the button even if the user views the scrolled screen information
Solution Approach 1:
The display is divided into two functional zones: the first area for scrolling content and the second area for fixed operational buttons. This segmentation allows users to scroll through content efficiently while maintaining constant awareness of available operations in the persistent second area.
Solution Approach 2:
The second area acts as an intermediary zone that captures and preserves buttons that would otherwise be lost during scrolling. It serves as a buffer between the scrolling first area and the user's need for continuous button visibility.
3Illumination intensity
If a magnifying glass enlarges screen information, then readability improves, but buttons may scroll out of the display area and become inaccessible
Solution Approach 1:
By separating buttons into the fixed second area, the invention ensures they remain accessible even when the first area is magnified or scrolled. The segmentation isolates operational elements from the magnification/scrolling effects applied to content.
Solution Approach 2:
The second area serves multiple functions: it displays status information and permanently hosts operational buttons. This multi-functionality allows the status bar to adapt to different display modes (including magnification) while maintaining button accessibility.

AI summary
This display device includes: an operation detector that detects an operation; a display that displays a screen including a first area capable of being scroll-displayed, and a second area; and a display controller that performs a control that displays, in the first area, display elements including a specific display element. The display controller scroll-displays the display elements displayed in the first area when the operation detector detects a scroll operation, and accommodatively displays the specific display element in the second area if, as a result of the scroll-display, the specific display element is scrolled in the direction of the second area and displayed.
