Pressure-Sensitive Touch Input Controller for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when attempting to execute applications on touch screens, as they may not achieve their intended purpose due to misinterpretation of touch inputs, leading to unnecessary manual navigation to find and select application icons.
Innovation Solution
An electronic device that determines the pressure state of a touch input to decide whether to display information or perform a function, using a controller to differentiate between first and second pressure conditions to automatically decide on the appropriate action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the electronic device displays information relating to touch input, then the user can see what was input, but the application cannot be executed
Solution Approach 1:
The patent changes the pressure parameter of the touch input to differentiate between information display mode and application execution mode. By detecting whether the pressure meets a preset threshold, the system determines whether to display the touch input information or directly execute the corresponding application, thus resolving the contradiction between showing input feedback and achieving quick execution.
2Productivity
If the electronic device executes application based on touch input, then the application runs quickly, but the user cannot see the touch input information
Solution Approach 1:
The system uses pressure threshold as a parameter change criterion to switch between two operational modes: when pressure exceeds the threshold, the system prioritizes execution efficiency and directly launches the application; when pressure is below the threshold, the system prioritizes information feedback and displays the touch input. This parameter-based differentiation resolves the contradiction between speed and information visibility.
3Reliability
If the user manually navigates to find application icon, then the user can locate the application, but it takes extra time and steps
Solution Approach 1:
The patent extracts the application execution function from the manual navigation process. By detecting the touch input on the application icon and automatically executing the corresponding application based on pressure detection, the system removes the unnecessary steps of manual search and selection, directly achieving application launch while maintaining accurate selection through the touch coordinate detection.
Solution Approach 2:
The system performs preliminary detection of the touch input characteristics (position and pressure) before execution. By pre-judging whether the touch is intended for information display or application execution based on pressure threshold, the system prepares the appropriate response in advance, eliminating the need for subsequent manual navigation and reducing the time to complete the application selection process.

AI summary
An electronic device operating based on a touch input includes a touch screen for receiving the touch input; and a controller for determining a pressure state corresponding to the touch input, when the pressure state satisfies a first pressure condition, controlling the touch screen to display information relating to the touch input, and, when the pressure state satisfies a second pressure condition, performing a function corresponding to the touch input. A method of controlling an electronic device based on a touch input includes determining a pressure state of a touch input; when it is determined that the pressure state satisfies a first pressure condition, displaying information relating to the touch input; and when it is determined that the pressure state satisfies a second pressure condition, performing a function corresponding to the touch input.
