Display Controller Prioritizing Items by Selection History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information terminal apparatuses with small display screens, not all display items can be shown in the information display area, leading to difficulties in selecting desired items for display.
Innovation Solution
An information display apparatus with a display, receiver, and display controller that uses selection record information to prioritize and display selected items at a reference position on the screen, allowing users to navigate through a list using flick operations to view all items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all display items are shown in the information display area, then the user can see all available items, but the display screen becomes too large or the item list becomes too long to fit on small screens
Solution Approach 1:
The item list is segmented into multiple pages or sections that can be navigated through. The display screen shows a manageable portion of items at a time, while navigation controls allow users to access other segments of the list, effectively dividing the overwhelming full list into accessible chunks.
Solution Approach 2:
The solution introduces temporal navigation through the list using flick operations. Instead of displaying all items simultaneously in space, the system allows users to traverse the list through time-based interaction sequences, accessing items in a sequential manner through rapid successive displays.
2Ease of operation
If items are displayed in fixed order, then the display structure is simple, but frequently used items may not be easily accessible
Solution Approach 1:
The system pre-processes the item list by identifying frequently used items based on usage history or importance criteria before display. This preliminary sorting or prioritization ensures that when the list is presented to the user, the most relevant items are already positioned for easy access, eliminating the need for users to search through the entire list.
Solution Approach 2:
The display system incorporates feedback mechanisms that track user interaction patterns and adjust the display order accordingly. Frequently selected items are automatically repositioned to more visible positions in the list, creating a dynamic adaptation that improves ease of operation over time while the underlying complexity is managed by the feedback loop.
3Area of stationary object
If the display shows only a portion of the item list, then the screen space is efficiently used, but users must navigate through multiple screens to find desired items
Solution Approach 1:
The item list display is made dynamic rather than static. The list automatically reorders or repositions items based on usage frequency, recency, or other relevance criteria. This dynamic adaptation ensures that the most likely desired items are always in prominent positions, reducing the time users need to search while maintaining efficient use of screen space.
Solution Approach 2:
The system changes the ordering parameter of the item list based on usage data. Instead of displaying items in a fixed alphabetical or categorical order, the display parameter is changed to reflect usage-based priority, with frequently used items positioned at the top or in highlighted positions, thereby reducing search time without requiring additional screen space.
Data Source
AI summary
An information display apparatus includes a display, a receiver, a memory, and a display controller. The display displays plural items in a list format in accordance with an order in a display field. The memory stores therein selection record information representing past record of selection of each of the plural items. The receiver receives an operation for updating items displayed in the display field based on the selection record information. The display controller specifies, when the operation is received by the receiver, at least one of the plural items by referring to the selection record information, and controls the display to display a part of the plural items including the specified item in the list format in accordance with the order in such a manner that the specified item is displayed at a reference position in the display field.
