Compact Keyboard Layout for Direct Multilingual Symbol Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional keyboard layouts are inefficient in terms of compactness, hand specialization, and language compatibility, leading to increased finger travel distance and the need for software-dependent processes to input symbols and characters, particularly for Western European and Greek languages.
Innovation Solution
A compact keyboard layout with 35 or 36 alphanumeric keys arranged in three rows, separating symbols and letters/numbers into distinct rows, allowing for language-invariant symbol placement, hand specialization, and the inclusion of extended Latin characters and Greek letters, along with a 'hack' key for customizable glyph input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If symbols are placed adjacent to alphabetical characters in the standard layout, then symbol input is accessible, but the keyboard lacks compactness and increases finger travel distance
Solution Approach 1:
The patent repositions symbol keys from the traditional horizontal arrangement adjacent to alphabetical keys to a vertical column on the right side of the keyboard. This dimensional reorganization allows symbols to remain easily accessible while maintaining a compact keyboard footprint, resolving the contradiction between symbol accessibility and keyboard compactness.
2Productivity
If a standard QWERTY layout is used, then alphabetical typing is efficient, but numeric input requires significant finger travel to the separate numeric keypad
Solution Approach 1:
The patent integrates the numeric keypad functionality directly into the alphabetical typing area by placing numeric keys adjacent to relevant alphabetical keys. This merging of numeric and alphabetical input zones eliminates the need for separate numeric keypad areas and reduces finger travel distance, while maintaining efficient alphabetical typing through the preserved QWERTY layout.
3Ease of manufacture
If a single keyboard layout is produced for mass distribution, then production costs are reduced, but it cannot accommodate extended Latin characters and Greek letters required by multiple languages
Solution Approach 1:
The patent designs a universal keyboard layout that incorporates keys capable of producing both standard ASCII characters and extended Latin/Greek characters. By strategically placing accented characters and Greek letters on the keyboard and providing mapping mechanisms, a single physical keyboard can serve multiple languages, achieving both cost-effective mass production and broad language compatibility.
4Adaptability or versatility
If software-dependent processes like dead keys and autocorrect are used for character input, then language flexibility is achieved, but typing speed is reduced and software complexity increases
Solution Approach 1:
The patent pre-arranges extended Latin characters and Greek letters on the keyboard in strategically positioned locations, allowing users to directly type these characters without relying on software processing. This preliminary placement of characters enables direct mechanical input, eliminating the need for dead keys and autocorrect software, thereby maintaining language flexibility while significantly improving typing speed.

AI summary
There is provided herein an improved keyboard layout that has a particular alphabetical, numerical, functional and symbolic key layout that enhances keyboard layout compactness and hand specialisation. The symbolic key layout allows for the incorporation of a much larger symbol character set wherein more frequently used symbols are more readily accessible and more conveniently located. This particular layout may be overlaid with extended Latin and, in embodiments, Greek characters to facilitate typing of most Western European languages in ways which do not affect the symbol key layout, facilitates finding of extended characters and offers one-to-one key mappings between basic and extended symbols for each language.
