Menu Display Device Spacing Adjustment for End Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot immediately determine when a menu item is at the end of the screen in existing scrolling user interfaces, as the screen contents do not change visibly when scrolling further.
Innovation Solution
A menu display device and method that includes means to display a range of menu items, move this range in response to user operations, determine if an item is at the screen's edge, and adjust the space between items to visually indicate the end, such as widening the space between the end item and its adjacent one.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional scrolling interface is used to display menu items, then the screen can display multiple menu items, but the user cannot immediately determine when a menu item is at the end of the screen
Solution Approach 1:
The patent applies visual changes to the spacing between menu items to indicate end position. When a menu item reaches the end of the screen, the space between that item and adjacent items changes (expands or changes appearance), providing visual feedback about the item's position without requiring additional information displays or complex interface elements.
2Ease of operation
If the screen displays a fixed range of menu items, then the display is simple and stable, but the user cannot intuitively understand when scrolling has reached the end
Solution Approach 1:
The patent applies local quality by making only the spacing around end-position menu items different from normal spacing. This localized visual change provides specific information about the menu item's position at the end, while the rest of the interface maintains its simple, stable appearance. The visual feedback is applied only where needed (at the boundaries) rather than throughout the entire interface.

AI summary
A menu display device includes: means for displaying on a screen a given range within a menu, in which a plurality of menu items are arranged in an array; means for moving the given range in response to a predetermined operation performed by a user; means for determining whether or not the menu item at an end within the menu is displayed in a predetermined position of the screen; and means for changing, when the menu item at the end is displayed in the predetermined position of the screen, the space between the menu items displayed on the screen in response to the predetermined operation performed by the user.
