Multilingual Input Correction via Machine Learning Gesture Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic correction methods for multilingual text processing are limited by their reliance on dictionaries and caching, which can be inaccurate and lack real-time performance, especially when handling keyboard layouts and language switches.
Innovation Solution
A method using a machine learning model to map sequences of user gestures to words across multiple languages, where each key on a multi-layout keyboard has a designated gesture as a delimiter, generating probabilities to determine the correct layout and apply corrections in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dictionary-based automatic correction methods are used, then language correction can be provided, but accuracy and real-time performance are limited
Solution Approach 1:
The patent replaces traditional dictionary-based mechanical lookup systems with a machine learning model that processes keyboard input sequences. The ML model predicts the intended language and layout dynamically, substituting the static dictionary approach with an adaptive intelligent system that achieves both high accuracy and real-time performance.
Solution Approach 2:
The system changes the parameter of language detection from static dictionary matching to dynamic probability-based prediction using machine learning. By computing probability distributions over possible languages and layouts based on input sequences, the system adapts to user behavior patterns while maintaining real-time correction capability.
2Reliability
If keyboard layout transformation methods are used, then incorrect key codes can be corrected, but language switching accuracy deteriorates
Solution Approach 1:
The system implements feedback by continuously monitoring keyboard input sequences and using the machine learning model to predict the user's intended language and layout. The correction is applied based on this predictive feedback, and the system adapts to user behavior patterns over time, improving both key code correction reliability and language switching accuracy.
Solution Approach 2:
The patent introduces dynamics by making the language and layout selection adaptive rather than static. The machine learning model dynamically adjusts language and layout predictions based on the current input sequence and learned user patterns, allowing the system to respond flexibly to changing typing contexts while maintaining accurate corrections.
3Measurement precision
If context cue methods are used, then language detection can be improved, but computational complexity increases
Solution Approach 1:
The system applies partial action by processing only the relevant portion of context information through the machine learning model. Instead of analyzing all possible context cues, the ML model focuses on the most discriminative features in the keyboard input sequence, achieving high language detection accuracy while keeping computational complexity manageable for real-time operation.

AI summary
A method and a device for automatically convert input typed using a multi layout physical or virtual keyboard to the correct layout. Some implementations also fix spelling mistakes and set the active layout to the desired layout. When a key such as the space bar is triggered, the implementation may feed the gestures into a machine learning model, the model then may output the estimated correct layout, and followingly cause replacing the characters, symbols or letters, corresponding to the typed keys in displayed words. Based on the estimated or detected language, the software of the implementation may check for spelling mistakes and will correct them.
