Multi-Line Character Input Using Adjustable Blank Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device keyboards lack diversity in text representation and efficiency in character input, particularly when handling multiple text lines, leading to cumbersome user interactions.
Innovation Solution
A method and device that facilitate character input by allowing selection of text lines and adjusting blank character widths, enabling characters to be placed in desired spatial arrangements across multiple lines using text line selection keys and blank width adjustment keys, along with gesture or key inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional keyboard input methods are used for multiple text lines, then character input is possible, but text representation diversity is limited and user interaction becomes cumbersome
Solution Approach 1:
The patent segments the text input area into multiple independent text lines, each capable of receiving character inputs separately. This segmentation allows diverse text representations across different lines while maintaining simple input operations for each line, resolving the contradiction between versatility and ease of operation.
Solution Approach 2:
The patent introduces a vertical dimension by arranging multiple text lines stacked vertically on the display screen. This dimensional change enables diverse text representations (multiple lines) without complicating the horizontal input process, as users can still input characters using traditional keyboard methods for each line.
2Ease of operation
If characters are input in multiple text lines without spatial arrangement control, then input process is simple, but desired spatial arrangements cannot be achieved
Solution Approach 1:
The patent implements dynamic adjustment of blank character widths between text lines. The blank width can be modified in real-time based on user input, allowing the spatial arrangement to adapt dynamically while keeping the input process simple. This resolves the contradiction by making the system flexible rather than fixed.
Solution Approach 2:
The patent changes the parameter of blank character width to control spatial arrangement. By adjusting this parameter, users can achieve desired character positioning across multiple text lines without complicating the input process, as the system automatically handles the spatial arrangement based on the modified parameter.
3Device complexity
If blank character widths are fixed, then system complexity is low, but spatial flexibility for character arrangement is limited
Solution Approach 1:
The patent applies preliminary action by pre-configuring blank characters between text lines with adjustable width properties. This preliminary setup enables spatial flexibility without requiring complex real-time calculations during input, as the blank width adjustment mechanism is prepared in advance and can be modified through simple user interactions.

AI summary
A method includes receiving an input of a first text line selection associated with a first text line if characters are positioned in a plurality of text lines including the first text line and a second text line in a text input area, receiving an input of a first character key associated with a first character among a plurality of keys, and providing the first character in the first text line associated with the first text line selection and a first blank character in each of the plurality of text lines except the first text line in the text input area.
