Touch Panel ECR Selection Display with Shortcut Keys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch panel Electronic Cash Registers (ECRs) require cumbersome swiping operations to display desired tabs and selection keys, making efficient content display inefficient.
Innovation Solution
A selection display apparatus and method featuring a display controller, first key controller, and second key controller that organize item keys by categories, window selection keys, and shortcut keys to efficiently display desired content by allowing direct access to frequently used categories without swiping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire area is made to slide by swiping operation to display the target tab or selection key, then the desired content can be displayed, but the operation becomes troublesome and inefficient
Solution Approach 1:
The patent applies preliminary action by displaying a plurality of frequently used tabs and selection keys in advance within the visible display screen area. These keys are pre-positioned based on usage frequency analysis, so that when an operator wants to access a frequently used function, it is already visible and accessible without requiring any swiping or scrolling operations. This resolves the contradiction by making the system proactive rather than reactive to user needs.
Solution Approach 2:
The patent applies local quality by differentiating the display treatment of frequently used tabs and selection keys from other less frequently used ones. Specifically, frequently used keys are displayed in a first display area that is always visible, while other keys are displayed in a second display area that requires swiping to access. This localized differentiation optimizes the most critical interaction points without compromising the completeness of the interface.
2Loss of information
If all tabs and selection keys are displayed in the display screen, then complete information is available, but frequently used keys require swiping operations to access
Solution Approach 1:
The patent applies segmentation by dividing the display screen into multiple distinct display areas: a first display area for frequently used tabs and selection keys that is always visible, and a second display area for other tabs and selection keys that can be accessed through swiping. This segmentation allows the system to prioritize frequently accessed functions in the always-visible area while maintaining access to all functions through the segmented second area, thus preserving information completeness while improving ease of operation for common tasks.

AI summary
A selection display apparatus includes a display controller which makes a window area in which an item key(s) for selecting an item is(are) displayed according to categories, a window selection key area in which window selection keys for selecting a category of items to be displayed in the window area are displayed, and a specific category selecting key for selecting a specific category among the categories be displayed in a display; a first key controller which, when one window selection key among window selection keys displayed in the window selection key area is operated, makes the item key corresponding to a category indicated be displayed by the window selection key in the window area; and a second key controller which, when the specific category selecting key is operated, makes the item key corresponding to the category indicated by the specific category selecting key be displayed in the window area.
