Dynamic Boundary Adjustment for Touch Input Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch-sensitive displays on portable electronic devices face challenges in efficiently managing user input and providing feedback, especially when handling continuous touches with unintended movements, which can lead to inaccurate navigation and information manipulation due to limited space and size constraints.
Innovation Solution
The solution involves a method for updating boundaries on a touch-sensitive display based on continuous touch locations, providing visual, audible, and tactile feedback, and adjusting the distance between boundaries to minimize the impact of unintended movements, allowing for precise control and intuitive user interaction.

Engineering Contradiction Analysis
1Weight of moving object
If the touch-sensitive display size is decreased to improve portability, then device portability is improved, but the accuracy of touch input and navigation deteriorates due to limited space
Solution Approach 1:
The patent implements dynamic boundary adjustment where the distance between boundaries is automatically modified based on detected touch movement patterns. When unintended movements are detected, the system increases the distance between boundaries to reduce sensitivity, while maintaining normal distance for intentional touches. This dynamic adaptation allows the system to maintain high touch input accuracy on small displays without sacrificing portability.
2Stability of the object's composition
If the distance between boundaries is increased to reduce sensitivity to unintended movements, then touch input stability is improved, but the precision for intentional navigation deteriorates
Solution Approach 1:
The system dynamically adjusts boundary distances based on real-time analysis of touch movement characteristics. When a touch is detected as intentional (following a deliberate path), the boundary distance is maintained at a normal level for precise navigation. When unintended movements are detected (erratic or accidental touches), the boundary distance is automatically increased to reduce sensitivity and improve stability. This dynamic switching resolves the contradiction between stability and precision.
Solution Approach 2:
The patent employs feedback mechanisms where the system continuously monitors touch patterns and adjusts boundary distances accordingly. The feedback loop analyzes touch velocity, direction changes, and pressure patterns to distinguish between intentional and unintended movements, then provides appropriate feedback by adjusting boundary sensitivity in real-time, maintaining both stability and precision as needed.

AI summary
A method includes detecting a continuous touch on a touch-sensitive display. A position of one or more boundaries is updated when the continuous touch crosses a first boundary of the one or more boundaries. Feedback is provided when the continuous touch crosses the first boundary.
