Dynamic Edge Suppression for Touch Screen False Touches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing touch screen edge suppression methods in mobile devices are not flexible enough, leading to false touches and user experience issues, especially when operating large screens with a single hand or during cross-screen operations on double-screen devices.
Innovation Solution
A method and apparatus that dynamically adjust edge suppression based on the portrait or landscape state of the touch screen, allowing edge suppression on certain edges in portrait mode and disabling it in landscape mode to prevent false touches and improve usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If edge suppression is added to prevent false touches during single-handed operation, then false touch rate is reduced, but usability of bottom edge and cross-screen operations deteriorates
Solution Approach 1:
The patent applies dynamics by making the edge suppression function adjustable and changeable based on different usage scenarios. The system dynamically switches between enabling and disabling edge suppression depending on whether single-handed operation or cross-screen operation is detected, allowing the touch screen to adapt its behavior to different user needs rather than maintaining a fixed suppression state
Solution Approach 2:
The patent applies local quality by selectively applying edge suppression to specific edges based on the detected usage scenario. When single-handed operation is detected, suppression is applied to the right edge; when cross-screen operation is detected, suppression is applied to the left edge. This localized approach ensures that suppression is applied only where needed rather than uniformly across all edges
2Reliability
If rectangular edge suppression region is used at bottom of single landscape screen, then false edge touch is prevented, but bottom edge touching becomes difficult and normal operations are suppressed
Solution Approach 1:
The system dynamically adjusts the edge suppression configuration based on the detected usage scenario. When single-handed operation is detected, the system enables suppression on the right edge; when cross-screen operation is detected, it enables suppression on the left edge. This dynamic adjustment ensures that suppression is applied only to the appropriate edge rather than uniformly to all edges including the bottom edge
Solution Approach 2:
The patent implements local quality by applying edge suppression selectively to specific edges based on the usage scenario. The suppression function is localized to the right edge during single-handed operation and to the left edge during cross-screen operation, rather than applying a uniform rectangular suppression region that would affect the entire bottom edge and interfere with normal operations
3Reliability
If fixed edge suppression is applied to touch screen, then false touches are reduced, but flexibility and adaptability to different usage scenarios deteriorates
Solution Approach 1:
The patent applies dynamics by implementing a detection mechanism that automatically identifies the current usage scenario (single-handed operation or cross-screen operation) and dynamically adjusts the edge suppression configuration accordingly. The system transitions from a fixed suppression state to a dynamic one where suppression is enabled or disabled and applied to different edges based on real-time detection of user behavior patterns
Solution Approach 2:
The system changes the parameters of edge suppression based on the detected usage scenario. When single-handed operation is detected, the suppression parameter is enabled for the right edge; when cross-screen operation is detected, the suppression parameter is enabled for the left edge. This parameter change approach allows the system to maintain reliability by applying suppression where needed while preserving flexibility through scenario-based parameter adjustment

AI summary
A method includes: detecting a current portrait or landscape state of a touch screen of a mobile terminal; determining that edge suppression is performed or no edge suppression is performed on an edge of the touch screen according to the portrait or landscape state of the mobile terminal; setting an edge suppression function of the touch screen according to a determination result, thereby solving the problem in the related art that that screen edge suppression of a touch screen of a mobile terminal is not flexible enough, flexibly setting a screen edge suppression function of the touch screen of the mobile terminal, and improving use convenience and user experience.
