QWERTY Key Layout Symbol Mapping and Input Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals with QWERTY key layouts require multiple key inputs and complex navigation to input symbols, as users cannot manage or edit symbol layouts, making the process cumbersome and inefficient.
Innovation Solution
A method and system that allows users to map symbols to QWERTY keys, enabling direct input and management of user-defined symbols through a key mapping table, with functions for adding, deleting, and changing symbols, displayed in a QWERTY key layout for easy selection and input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If symbols are displayed in a menu form with lateral or vertical direction keys for selection, then symbols can be displayed in a designated layout order, but multiple key inputs are necessary and users cannot manage or edit the symbol layout
Solution Approach 1:
The patent segments the symbol input process into two distinct modes: a symbol setting mode where users can define and arrange symbols on the QWERTY keyboard layout, and a symbol input mode where predefined symbols are directly input. This segmentation allows users to customize symbol positions once, and then benefit from simplified input thereafter, reducing the complexity of repeated key inputs
Solution Approach 2:
The patent implements preliminary action by allowing users to pre-arrange symbols on the QWERTY keyboard in a desired layout during the symbol setting mode. This preliminary arrangement is stored in the controller, so when symbol input is needed, users can directly press the corresponding key without navigating through multiple menu levels, thus simplifying the actual symbol input process
2Productivity
If a specific key for displaying symbols is input in a message writing mode, then symbols can be displayed, but multiple key inputs are necessary and users must find desired symbols among symbols of a designated layout
Solution Approach 1:
Users perform preliminary arrangement of symbols on the QWERTY keyboard layout in the symbol setting mode, positioning frequently used symbols in easily accessible locations. This preliminary configuration is stored and automatically applied during symbol input, eliminating the need to search through menu hierarchies and significantly reducing the time required to locate and input desired symbols
Solution Approach 2:
The system provides self-service by allowing users to customize their own symbol layout according to their personal preferences and usage patterns. Once configured, the system automatically uses this customized layout without requiring users to repeatedly navigate through standard menu structures, thereby improving symbol input efficiency and reducing time loss
3Stability of the object's composition
If symbols are displayed in a designated layout order, then symbols can be managed in a fixed structure, but users cannot manage or edit the symbol layout
Solution Approach 1:
The patent implements dynamics by providing two distinct operational modes: a symbol setting mode where the symbol layout is dynamic and can be freely customized by users, and a symbol input mode where the layout becomes stable and fixed for consistent input. The controller dynamically switches between these modes based on user input, allowing the system to adapt between stability and flexibility as needed
Solution Approach 2:
The QWERTY keyboard serves multiple functions: it acts as both the standard character input interface and the symbol selection interface. By making the keyboard universal for both text and symbol input, the patent eliminates the need for separate menu navigation structures, allowing users to maintain a stable familiar layout while gaining the adaptability to customize symbol positions according to their preferences

AI summary
A mobile terminal having a QWERTY key layout and a method of setting and inputting a symbol therein are provided. The method of setting a symbol in a mobile terminal having a QWERTY key layout includes selecting a setting function of a symbol defined a user; adding, if the selected setting function comprises an addition function, a selected symbol to a key mapping table, deleting, if the selected setting function comprises a deletion function, a selected symbol from the key mapping table, and changing, if the selected setting function comprises a change function, a selected symbol to another selected symbol. Therefore, symbols frequently used by a user can be viewed in one screen, thereby minimizing steps for searching for a desired symbol. Further, a symbol set by the user can be immediately determined by displaying symbols mapped to each key of a key input unit with a QWERTY key layout, and thus a character including a symbol can be easily input, thereby improving user convenience.
