Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual interfaces on user devices, such as keyboards, are not adaptable to individual user preferences, leading to inefficiencies and errors due to varying finger size, dexterity, and usage habits, as they maintain fixed sizes and dimensions for all users.
Innovation Solution
A dynamic virtual interface adjustment system that includes an input pattern facility, adjustment configuration facility, and storage facility to detect erroneous input patterns and adjust the interface by shifting virtual input objects to prevent unintentional inputs, using data from user input and context attributes like device orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-size virtual interface components are used for all users, then device complexity is reduced and ease of manufacture is improved, but adaptability to individual user preferences deteriorates and input accuracy decreases
Solution Approach 1:
The virtual interface transitions from a static, fixed-size design to a dynamic system that automatically adjusts component sizes and positions based on detected user input patterns. The system monitors typing behavior over time and modifies the virtual keyboard layout dynamically to optimize for each user's dexterity and preferences, resolving the contradiction between adaptability and complexity through automated adaptation.
Solution Approach 2:
The system employs machine learning algorithms that enable the virtual interface to self-adjust without user intervention. By analyzing input patterns autonomously and automatically reconfiguring the interface layout, the system eliminates the need for manual customization while achieving high adaptability, thus resolving the contradiction between personalization and complexity.
2Measurement precision
If standard virtual keyboard sizes are used, then ease of operation is maintained across devices, but input accuracy deteriorates due to varying finger sizes and dexterity
Solution Approach 1:
The system applies different sizing and positioning adjustments to different regions of the virtual keyboard based on local input patterns. Rather than uniformly scaling the entire keyboard, it selectively modifies specific keys or key regions where the user demonstrates difficulty, optimizing input accuracy for each user's unique finger size and dexterity while maintaining overall interface simplicity.
3Reliability
If uniform virtual interface dimensions are applied, then productivity is maintained through consistent operation, but reliability deteriorates due to increased errors from poor fit
Solution Approach 1:
The system continuously monitors user input accuracy and typing patterns, using this feedback to iteratively refine the virtual interface configuration. By detecting errors and adjusting the keyboard layout in response to performance data, the system improves input reliability over time while maintaining or enhancing typing efficiency through optimized key positioning that reduces mistakes and corrections.

AI summary
An exemplary method includes a virtual interface adjustment system detecting, based on user input data associated with user input received by way of a virtual interface of a user device, an erroneous input pattern that includes at least one unintentional input, determining, based on the erroneous input pattern, an adjustment procedure configured to adjust the virtual interface to avert future unintentional inputs that correspond to the at least one unintentional input of the erroneous input pattern, determining an adjustment procedure trigger for the adjustment procedure, activating the adjustment procedure trigger, detecting, after the activating, an occurrence of the adjustment procedure trigger, and executing, in response to the detecting of the occurrence of the adjustment procedure trigger, the adjustment procedure to avert the future unintentional inputs that correspond to the at least one unintentional input of the erroneous input pattern.
