Arabic Keyboard Input via Extended ASCII Code Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard keyboards are not user-friendly for typing in languages like Arabic, as they lack corresponding keys and require cumbersome improvisations or diacritic chording systems, which are time-consuming and inefficient.
Innovation Solution
A method and system that expand the standard ASCII code to an extended code, allowing users to type Arabic letters and characters on a standard Latin keyboard by pressing corresponding keys, double-clicking for similar letters, and using the number row for vowel points, enabling intuitive and efficient typing without additional key presses or SHIFT usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard Latin keyboard is used for typing Arabic, then the keyboard is universally available, but the typing process becomes complicated and time-consuming due to lack of corresponding keys
Solution Approach 1:
The patent introduces an intermediary software layer that maps standard Latin keyboard keys to Arabic characters. This mediator translates the user's Latin keyboard inputs into corresponding Arabic characters, allowing standard keyboards to function for Arabic typing without requiring physical keyboard modifications.
Solution Approach 2:
The system changes the functional parameters of the keyboard by implementing multiple typing modes (Arabic mode, English mode, and mixed mode) that can be switched between. This allows the same physical keyboard to operate with different character mappings depending on the selected mode, resolving the contradiction between universal availability and language-specific functionality.
2Adaptability or versatility
If diacritic chording systems are used to generate Arabic characters, then character generation is possible on standard keyboards, but the process becomes complicated and time-consuming
Solution Approach 1:
The patent segments the Arabic alphabet into groups based on visual similarity to Latin characters and assigns corresponding keys accordingly. This segmentation allows users to type Arabic characters using intuitive key mappings rather than complex chord combinations, reducing the cognitive load and typing complexity.
Solution Approach 2:
Instead of requiring users to press multiple keys in specific sequences (chording) to generate Arabic characters, the system inverts the approach by mapping single Latin keys to Arabic characters through software translation. This inversion simplifies the input process from complex multi-key sequences to simple single-key presses.
3Ease of operation
If Arabic letters without corresponding Latin letters are typed using improvisation, then typing is possible on standard keyboards, but the expression becomes inaccurate and time-consuming
Solution Approach 1:
The patent creates a mapping system that copies the visual appearance and phonetic properties of Arabic letters onto the standard Latin keyboard layout. By assigning Latin keys to represent Arabic characters based on visual similarity and sound correspondence, the system enables accurate Arabic typing without requiring users to improvise or use approximations.
4Adaptability or versatility
If vowel points are typed using standard Arabic keyboard, then complete Arabic typing is possible, but additional key presses and SHIFT keys are required which reduces typing speed
Solution Approach 1:
The patent merges the vowel point typing functionality with the existing Latin keyboard layout by assigning vowel point keys to positions that do not interfere with consonant typing. This integration allows users to type both consonants and vowel points using a unified keyboard scheme without requiring separate key sequences or additional SHIFT presses, thereby maintaining high typing speed while preserving complete Arabic typing capability.

AI summary
Method and system for generating letters and characters in a certain language using a standard Latin keyboard, according to which the letters of the certain language which have corresponding Latin letters are generated by pressing the corresponding Latin letter keys, using the standard ASCII code of the keyboard. The standard ASCII code is expanded to an extended code that can represent certain language letters which do not have corresponding Latin letters and certain language letters which do not have corresponding Latin letters but look similar to, or associated with, another certain language letters that do correspond to Latin letters, using the extended code. Certain language letters which do not have corresponding Latin letters are generated by typing the keys where the certain language letters are located on a standard Latin keyboard of the certain language, using the extended code. Then certain language letters which do not have corresponding Latin letters but look similar to, or associated with, another certain language letters that do correspond to Latin letters are generated using the extended code, by double clicking on the corresponding Latin letter keys. Finally, certain language letters which do not have corresponding Latin letters but look similar to another certain language letters that are generated are generated by double clicking the letters that are generated, using the extended code.
