Touch Keyboard Pressure Thresholds for Accurate Content Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch keyboards lack tactile feedback, leading to inadvertent touches and reduced typing efficiency and user experience due to their sensitivity, making blind typing difficult and causing user fatigue.
Innovation Solution
A content input method for touch input devices that sets pressure thresholds to differentiate between intended and inadvertent touches, allowing for improved typing efficiency and user experience by ignoring inadvertent touches and providing feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If touch-type keyboard is used to replace mechanical key type, then device versatility is improved, but input accuracy deteriorates due to inadvertent touches
Solution Approach 1:
The patent changes the pressure threshold parameter to differentiate between intentional and accidental touches. By setting a specific pressure threshold, the system can distinguish between light inadvertent touches (which should be ignored) and deliberate typing actions (which should be recognized), thereby improving input accuracy while maintaining the versatility of touch-type keyboard.
2Ease of operation
If touch-sensitive display is made highly sensitive for responsive input, then ease of operation is improved, but reliability deteriorates due to false triggers
Solution Approach 1:
The patent adjusts the pressure threshold parameter to filter out false triggers. By setting an appropriate pressure threshold, the system maintains high sensitivity for user interaction while eliminating spurious inputs caused by palm contact or accidental touches, thus improving reliability without sacrificing ease of operation.
3Productivity
If pressure sensitivity is increased for better touch response, then productivity is improved, but loss of information increases due to inadvertent input
Solution Approach 1:
The patent optimizes the pressure threshold parameter to balance productivity and information accuracy. By setting the threshold at an optimal level, the system captures legitimate typing actions that boost productivity while filtering out inadvertent touches that would cause information loss, achieving both goals simultaneously.

AI summary
The disclosure relates to a content input method, touch input device, and storage medium. The content input method includes: obtaining pressure information applied to a first preset area of a display area; determining, according to a first pressure threshold, whether the pressure information applied to the first preset area is inadvertent touch information; if the pressure information applied to the first preset area is the inadvertent touch information, ignoring the pressure information.
