Graphical Input via Image-Pixel Keys for Unicode Text
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device input methods for social network services lack diversity in text representation, particularly in visual context, as they primarily rely on literal interpretations of Unicode characters rather than graphical concepts across multiple text lines.
Innovation Solution
A method and device configuration that displays a keyboard area with image-pixel keys associated with pseudo-image parts, allowing users to input Unicode characters that represent graphical concepts by arranging visual marks across multiple text lines, enabling the representation of complex graphical objects like faces, animals, and natural scenes through a combination of upper and lower pseudo-image parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional Unicode character input methods are used, then input simplicity is maintained, but text representation diversity and visual context are limited
Solution Approach 1:
The keyboard is segmented into multiple functional areas: traditional character input zones and a dedicated graphical input zone with image-pixel keys. This segmentation allows the system to maintain traditional input simplicity while adding graphical representation capabilities, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The patent introduces a new dimension of input by adding image-pixel keys that operate alongside traditional character keys. This dimensional expansion enables graphical concept input without eliminating conventional text input methods, thereby increasing text representation diversity while maintaining system manageability.
2Loss of information
If graphical concepts are represented using multiple Unicode characters across text lines, then visual context is improved, but input time and complexity increase
Solution Approach 1:
The keyboard pre-configures image-pixel keys with associated Unicode character sequences that represent graphical concepts. When a user activates an image-pixel key, the corresponding sequence is automatically inserted across multiple text lines, preserving visual context while eliminating the time-consuming manual input of individual characters.
Solution Approach 2:
The system uses copying by pre-defining graphical concept representations as reusable Unicode sequences. Image-pixel keys act as shortcuts that copy and insert these pre-formed sequences, maintaining visual context integrity while significantly reducing input time compared to manual character-by-character entry.
3Productivity
If manual copying and pasting of Unicode characters is required, then input flexibility is maintained, but user experience and efficiency deteriorate
Solution Approach 1:
The keyboard provides self-service by automatically managing the insertion and arrangement of Unicode character sequences when image-pixel keys are activated. The system handles the complex task of multi-line sequence insertion without requiring users to manually copy and paste characters, thereby improving both input efficiency and ease of operation.
Solution Approach 2:
Image-pixel keys serve as intermediaries between the user and the complex Unicode character sequences. Instead of directly manipulating multiple characters, users interact with simplified image-pixel keys that mediate the insertion process, making the system easier to operate while maintaining high input efficiency.

AI summary
A method includes displaying a first screen of a keyboard area having an upper pseudo-image part, a lower pseudo-image part, and multiple image-pixel keys, changing a Unicode character in one of the upper pseudo-image part and the lower pseudo-image part into a first non-blank Unicode character in the first screen in response to a first image-pixel key input, displaying a second screen of the keyboard area different from the first screen, providing the upper pseudo-image part in a text input area in response to a first image-part key input, providing a word in the text input area in response to at least one letter key input, and providing the lower pseudo-image part in the text input area in response to a second image-part key input.
