Information Display System with Auto-Scroll Banner Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems require users to scroll back to re-display items that have been moved outside the display range, which can be inconvenient and inefficient.
Innovation Solution
A computer-readable medium storing a program that changes the display positions of items on a screen based on scroll operations and automatically re-displays specific items as simplified banners when they are scrolled out, allowing users to access them without reversing the scroll operation, and enables editing and deletion of these banners through user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users perform scroll operations to navigate through items on the screen, then the display can show more items by scrolling, but items that are scrolled out cannot be accessed without scrolling back
Solution Approach 1:
The system performs preliminary action by automatically re-displaying scrolled-out items as simplified banners before the user needs to access them again. When an item is scrolled out, the system creates a banner representation and places it at the top of the display area, preparing it for quick access without requiring the user to scroll back through the entire list.
Solution Approach 2:
The simplified banner acts as an intermediary between the scrolled-out item and the user. Instead of requiring direct access to the original item by scrolling back, the banner serves as a mediator that represents the scrolled-out item and allows users to quickly access it through a separate interaction mechanism.
2Ease of operation
If the system automatically re-displays scrolled-out items, then item accessibility is improved, but the display area is occupied by additional banner elements
Solution Approach 1:
The system segments the display into different functional areas: the main display area for currently visible items and a separate banner area at the top for re-displaying scrolled-out items. This segmentation allows the banner to occupy a limited, dedicated space without interfering with the main scrolling functionality.
Solution Approach 2:
The system uses the vertical dimension by placing banners at the top of the display area, above the main scrolling content. This dimensional arrangement allows banners to coexist with the scrollable items without occupying horizontal space that would interfere with the primary display function.
3Ease of operation
If simplified banners are displayed for scrolled-out items, then users can access items without scrolling back, but the banners may be accidentally deleted or modified
Solution Approach 1:
The system implements feedback mechanisms where banners respond to user interactions in predictable ways. When users tap or select a banner, it provides feedback by expanding to show the full item details or initiating the appropriate action. This controlled feedback loop prevents accidental modifications while maintaining ease of access.
Solution Approach 2:
Instead of making banners easily modifiable like regular items, the system inverts the interaction model: banners are designed to be stable and resistant to accidental changes, while requiring deliberate user actions to access the full item details. This inversion of the typical item-banner relationship prioritizes stability over editability.

AI summary
A non-transitory computer readable medium stores a program causing a computer to execute a process for information processing. The process includes changing display positions of plural items in accordance with a direction of a scroll operation on a screen, and stopping the scroll operation when a specific item among the plural items has been moved outside a display range in response to the scroll operation or displaying the specific item on part of the screen when an input is provided to a predetermined region on the screen.
