Touchscreen Keypad Configuration Switching via Segmented Identifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable terminals are inconvenient for users to change input modes, requiring multiple selections to switch between different keypad configurations for data input.
Innovation Solution
A method and portable terminal design that displays multiple identifiers for different keypad configurations, allowing users to easily select and switch between them using touch events on a touchscreen, with a controller managing the display to show the corresponding keypad configuration in the center and the selected identifier adjacent to it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional input mode switching is used, then multiple keypad configurations are available, but the operation becomes complex and time-consuming requiring multiple selections
Solution Approach 1:
The patent displays multiple keypad configurations in advance as selectable options before the user needs to input data. This preliminary presentation of available configurations allows users to quickly select their desired input mode without having to navigate through multiple menu levels or perform sequential selections, thereby improving ease of operation while maintaining adaptability.
2Adaptability or versatility
If multiple selections are required to switch input modes, then various keypad configurations can be accessed, but the time consumption increases
Solution Approach 1:
The patent segments the keypad configuration selection process by displaying multiple discrete keypad configuration options simultaneously as separate, selectable elements. This segmentation allows users to directly access and select any desired configuration in a single action rather than navigating through hierarchical menus requiring multiple sequential selections, significantly reducing time loss while maintaining access to various configurations.
Data Source
AI summary
A method for displaying different keypad configurations to allow input data using a touch screen with an appropriate keypad configuration is provided. The method comprises: displaying a plurality of identifiers respectively representing keypad configurations whose input modes are different from each other; and displaying a keypad configuration corresponding to a selected identifier when a touch event, which selects one of the displayed plurality of identifiers, is generated.
