Dynamic Touch-Screen Keyboard Layout for Symbol Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input methods for symbols on portable consumer devices in mobile communication networks, such as those using reduced key keyboards or touch-screens, are cumbersome and inefficient, requiring multi-tapping or relying on prediction algorithms like T9 or WordWise, which do not provide intuitive handling.
Innovation Solution
A graphical user interface that divides the symbol set into subsets, displaying the most commonly used symbols and dynamically changing secondary symbols based on the last input, using a linguistic database to predict the next intended symbol, thereby reducing user effort and improving input speed and intuitiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a reduced key keyboard is used in portable devices, then device portability is improved, but symbol input efficiency deteriorates
Solution Approach 1:
The keyboard layout dynamically adapts based on the last input symbol, automatically displaying the most relevant next symbols in prominent positions. This dynamic reconfiguration allows the reduced keyboard to provide efficient access to frequently needed symbols without requiring physical expansion of the device.
Solution Approach 2:
The system pre-positions the most likely next symbols in prominent keyboard locations based on linguistic analysis and usage patterns. By anticipating user needs before they occur, the system reduces the time and effort required for symbol input while maintaining a compact keyboard layout.
2Adaptability or versatility
If multi-tapping is used to input different symbols with one key, then symbol variety is improved, but input time increases
Solution Approach 1:
The system pre-positions the most likely next symbols in prominent keyboard locations based on linguistic analysis and usage patterns. By anticipating user needs before they occur, the system reduces the time and effort required for symbol input while maintaining access to a wide variety of symbols.
Solution Approach 2:
The system continuously analyzes the sequence of input symbols and adjusts the keyboard layout in real-time based on linguistic patterns and predicted next symbols. This feedback mechanism allows the system to optimize symbol access dynamically, reducing input time while maintaining symbol variety.
3Productivity
If prediction algorithms like T9 or WordWise are used, then input speed is improved, but handling intuitiveness deteriorates
Solution Approach 1:
The keyboard layout dynamically adapts based on the last input symbol, automatically displaying the most relevant next symbols in prominent positions. This dynamic reconfiguration provides intuitive visual feedback that matches user expectations, making the input process both fast and natural.
Solution Approach 2:
The system visually distinguishes prominent symbols from other symbols on the keyboard, likely through size, position, or visual emphasis. This visual differentiation makes it immediately clear which symbols are most relevant, enhancing intuitiveness while maintaining input speed.
