Smartphone Key Region Mis-Touch Avoidance via Dynamic Pressure Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intelligent terminals, such as smartphones, the key region is easily mis-touched during certain activities like gaming, leading to inconvenient pauses and disruptions in user experience due to accidental activation of keys like the menu button.
Innovation Solution
An information processing method and apparatus that determine whether the display output state satisfies specific conditions, triggering a mis-touch avoidance mode where the key region becomes unresponsive to certain types of operations, preventing accidental key presses by determining if an operation meets preset conditions such as gentle touch or small pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the key region is made responsive to all touch operations, then the ease of operation is improved, but the reliability deteriorates due to mis-touches
Solution Approach 1:
The patent changes the parameter of touch pressure threshold to distinguish between intentional key presses and accidental mis-touches. By setting a specific pressure threshold, the system maintains responsiveness for deliberate actions while filtering out spurious inputs during gaming activities.
Solution Approach 2:
The patent dynamically adjusts the key region's responsiveness based on the detected activity type. During gaming, the key region is set to ignore low-pressure touches, while during normal navigation, it remains fully responsive. This dynamic state change resolves the contradiction between constant responsiveness and mis-touch avoidance.
2Reliability
If the key region is made unresponsive to prevent mis-touches, then the reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The system dynamically switches between responsive and unresponsive states based on activity detection. When gaming is detected, the key region becomes unresponsive to prevent mis-touches. When gaming is not detected, it returns to responsive state for normal operation, thus maintaining ease of operation when needed.
Solution Approach 2:
The patent changes the operational parameter (responsiveness) based on the detected activity context. By adjusting the touch response parameter dynamically, the system achieves high reliability during gaming without permanently sacrificing ease of operation during normal use.
3Productivity
If the display screen uses larger size, then the productivity is improved, but the key region becomes smaller and more prone to mis-touches
Solution Approach 1:
The patent changes the pressure threshold parameter to compensate for the smaller effective key area on larger displays. By adjusting the pressure sensitivity parameter, the system maintains reliable key detection despite the reduced physical size of the key region on larger screen devices.

AI summary
An information processing method, an electronic device, and an information processing apparatus are provided. The information processing method comprises determining whether a display output state of a display screen satisfies a first preset condition; in response to the first preset condition being satisfied, controlling a key region to be in a mis-touch avoidance mode; in the mis-touch avoidance mode, in response to a first operation at the key region being detected, determining whether the first operation satisfies a second preset condition; and in response to the second preset condition being satisfied, controlling the key region to be unresponsive to the first operation.
