Touch Character Input via Component Grid and Gesture Combination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional character input systems on touch-based electronic devices require a large number of input motions to form and edit block characters, making them inefficient and time-consuming.
Innovation Solution
A system and method that allows users to input characters by combining characters through specific touch interactions such as draw, draw-and-backtrack-flick, and draw-and-backtrack-drag gestures, enabling rapid character formation and correction without deleting existing characters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional character input systems are used, then characters can be input on touch screens, but users must repeatedly perform multiple input motions to form block characters, increasing input time
Solution Approach 1:
The system pre-positions character components (consonants and vowels) in a grid layout before user input. When a user touches a cell, the corresponding character component is automatically selected and combined with previously input components, eliminating the need for repeated manual input motions to assemble block characters.
Solution Approach 2:
The patent introduces an intermediary character combination mechanism that automatically assembles block characters by combining pre-selected character components based on touch input sequences. This intermediary process reduces the number of direct user input motions needed to form complete characters.
2Ease of operation
If conventional character input systems are used, then characters can be input, but users must delete and re-input characters to correct errors, increasing the number of input motions
Solution Approach 1:
The system maintains a dynamic grid of selectable character components that can be modified during input. When an error is detected or correction is needed, the system allows modification of existing character components in the grid without requiring deletion of the entire block character, enabling correction through preliminary adjustment of individual components.
Solution Approach 2:
The character input system dynamically adjusts the grid of character components based on user interactions. The grid can be modified in real-time during the input process, allowing users to correct errors by adjusting individual components rather than deleting and re-inputting entire characters, thereby reducing input motion complexity.
3Productivity
If conventional character input systems are used, then block characters can be formed, but the input process requires repeated motions to form each character
Solution Approach 1:
The system pre-arranges character components in a grid structure before user input begins. This preliminary organization allows users to access and combine characters through single or double touch motions rather than repeated input motions, significantly improving productivity and reducing the time required to form block characters.
Solution Approach 2:
The patent merges multiple character formation operations into a single input action. By combining pre-positioned character components through one touch or a sequence of touches, the system forms complete block characters in a single operational step rather than requiring repeated separate input motions for each character component.

AI summary
A character input system and method is provided that enables a user to input and edit block characters via a touch-based electronic device, with a limited number of input motions. The character input method includes receiving a first interaction, displaying a first character in response to the first interaction, receiving a second interaction successively after the first interaction, identifying a second character that is formed by combining the first character with a character according to the second interaction, and displaying the second character instead of the first character.
