Touch Screen Korean Character Input Using Consonant-Vowel Grid Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Korean character input methods on touch screens require a large number of key strokes, leading to increased possibilities of erroneous input and prolonged character input times, especially for frequent Korean character input.
Innovation Solution
A Korean character input apparatus and method that reduces the number of character input keys on a touch screen by using a grid structure with consonant and vowel input keys, where vowels are selected through touch and dragging gestures to automatically combine with consonants, simplifying the input process and reducing key strokes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional Korean character input methods are used on touch screens, then complete character input functionality is achieved, but the number of key strokes increases excessively
Solution Approach 1:
The patent combines the consonant and vowel input keys into a single integrated input window on the touch screen. When a user touches a vowel input key, the system automatically combines it with the previously selected consonant to form a complete Korean character, eliminating the need for separate consonant and vowel input steps and reducing the total number of key strokes.
Solution Approach 2:
The system performs preliminary selection of consonants and stores them in memory before vowel input. When the user subsequently touches a vowel key, the pre-selected consonant is automatically combined with the selected vowel, eliminating the need to re-input the consonant and reducing redundant operations.
2Ease of operation
If phoneme combination scheme is used for Korean character input, then character typing can be learned easily, but a large number of key strokes is required due to the composition of vowels
Solution Approach 1:
The patent merges the consonant and vowel input operations into a single touch action. By integrating the vowel input key with the consonant selection mechanism, the system reduces multiple sequential key strokes into a single operation, thereby increasing character input speed while preserving the ease of learning through consistent visual patterns.
3Productivity
If visual reinterpretation method is used for Korean character input, then character reconstruction is achieved, but a large number of key strokes is required for consonant input and it is not easy to learn
Solution Approach 1:
The patent segments the Korean character input process into distinct consonant and vowel input keys arranged in a visually intuitive grid pattern. This segmentation allows users to select consonants and vowels independently through simple touch gestures, reducing the complexity of learning while maintaining complete character reconstruction functionality.
4Productivity
If conventional Korean character input methods are used, then complete character input capability is achieved, but input time is excessively prolonged
Solution Approach 1:
The system performs preliminary selection and storage of consonants in memory before vowel input occurs. When a vowel key is touched, the pre-selected consonant is immediately combined with the vowel to form the complete character, eliminating redundant input steps and significantly reducing the time required for character input while maintaining full input capability.

AI summary
A Korean character input apparatus using a touch screen is provided. The apparatus includes an input window comprising a consonant input key, a “” vowel input key to the right of the consonant input key, and a “” vowel input key under the consonant input key, a character combining means by which, when one of the “” vowel input key and the “” vowel input key is touch-selected, a consonant corresponding to the consonant input key provided to the left of the “” vowel input key or provided above the “” vowel input key is selected as an initial consonant and is combined with a vowel, an output window for displaying the composed Korean character, and a controller for controlling a touch input on the input window and an output of the composed Korean character on the output window.
